1978 1(3) 63-73 Josef Bogner A critical list of the aroid genera (Buy)
ABSTRACT: Engler's system of the aroids, over one hundred years old, is based not only on floral structures, but also uses vegetative and anatomical characters. His system is still viable and no large changes are necessary today. His arrangement shows a natural phylogenetic system and it has been accepted by all serious students of the family (M. R. Birdsey, G. S. Bunting, T. Croat, M. Madison, D. H. Nicolson, M. Hotta (with a few modifications).

1979 2(1) 26-27 Josef Bogner Professor Dr. Kurt Krause: 1883-1963
This article available FREE to IAS Members with a PERSONAL login. LOGIN, REGISTER or JOIN
ABSTRACT: The name K. Krause is well known to aroid lovers; it appears often as author, alone or together with A. Engler, in which case as Engl. et Krause. K. Krause was for a long time an expert on Araceae.

1979 2(4) 110-121 Josef Bogner Two new Aridarum species and one new variety from Sarawak (Buy)
ABSTRACT: Aridarum nicolsonii Bogner sp. nov., Aridarum burtii Bogner et Nicolson sp. nov. and Aridarum caulescens M. Hotta var. angustifolium Bogner et Nicolson var. nov. are described and a key presented.

1980 3(1) 4-12 Josef Bogner The genus Scaphispatha Brong. ex Schott (Buy)
ABSTRACT: The genus Scaphispatha was published by H. W. Schott in the year 1860 using this name given by A. Brongniart in the herbarium of the Museum National d'Histoire N aturelle in Paris on the sheet of d'Orbigny's type collection from Bolivia. Scaphispatha is monotypic and the single species, Scaphispatha gracilis Brongn. ex Schott, has been collected only four times in the last 150 years. Besides the Bolivian type collection by d 'Orbigny , the three others all came from Brazil; one from Para, and the other two from the same locality in Ceara. Since the inflorescence appears before the leaves, the leaves were unknown until 1977, when living tubers collected by myself in the Serra do Araripe, Ceara, produced leaves in cultivation in the Botanischer Garten Mlinchen. Now it is possible to give a full description of this rare aroid.

1980 3(2) 60-61 Josef Bogner Samuel Buchet 1875-1956

ABSTRACT: Samuel Buchet was a French botanist, born on May 23, 1875 in Roanne (Loire) and died on February 21, 1956 in Le Noyer (Cher), where he lived his last years.

1980 3(3) 75-85 Josef Bogner On two Nephthytis species from Gabon and Ghana (Buy)
ABSTRACT: Nephthytis hallaei (Bogner) Bogner comb. nov. Callopsis hallaei Bogner, Adansonia, ser. 2, 9: 285-291, pI. 1 (1969). and Nephthytis swainei Bogner sp. nov. are described.

1980 3(4) 134-143 Josef Bogner The genus Bucephalandra Schott (Buy)
ABSTRACT: The genus Bucephalandra Schott has been for a long time misinterpreted, because of an inaccurate description and an erroneous drawing by Schott (1858, 1860) showing a parietal placentation and the absence of flat staminodes between the female and male flowers. It seems that nobody since Schott has examined the holotype of Bucephalandra motleyana Schott, the type species. The holotype, Motley 404 (K), clearly shows a basal placentation and flat staminodes between the female and male flowers.

1981 4(1) 31-37 Josef Bogner Pseudohydrosme gabunensis Engl. (Buy)
ABSTRACT: The genus Pseudohydrosme was described by Engler (1892) from incomplete material with two species native in Gabon: P. gabunensis Engl. and P. buettneri Engl. During my collecting trip to Gabon in the year 1973, I especially looked for these species and I scheduled my visit to coincide with the flowering time of the two aroids, but they are so rare that I only found two specimens of P. gabunensis.

1981 4(2) 43-53 Josef Bogner Amorphophallus titanum (Becc.) Becc. ex Arcangeli (Buy)
ABSTRACT: The biggest flower in the plant kingdom is produced by the parasitic Rafflesia (Rafflesiaceae), which Â· can reach up to nearly 1 m in diameter; this genus is distributed in Southeast Asia. The biggest inflorescences (consisting of many single flowers) are probably in the palms and, depending on how one looks at it, the bamboos. But the genus Amorphophallus of the aroids has the biggest unbranched inflorescences in the plant kingdom.

1981 4(2) 57-63 Josef Bogner A new Aridarum species from Borneo (Buy)
ABSTRACT: Aridarum annae Bogner, sp. nov. is described.

1981 4(4) 109-113 Prof. Dr. W. Barthlott, Josef Bogner Rediscovery of Amorphophallus staudtii (Engl.) N. E. Br. in the Tai National Park (Buy)
ABSTRACT: The genus Amorphophallus Bl. ex Decne. is distributed in the palaeotropics with nearly one hundred species. One very rare taxon, Amorphophallus staudtii (Engl.) N.E.Br. wasrediscovered by the first author (W .B.) in the Ivory Coast 81 years after the first and only collection in the Cameroons. A detailed description and illustrations of the species and its natural habitat are given.

1984 7(2) 36-41 Mark D. Moffler, Josef Bogner A new Homalomena species (Araceae) from Columbia (Buy)
ABSTRACT: Homalomena speariae Bogner et Moffler from Colombia, South America, differs from the closely related H. wallisii Regel by the longer unconstricted spathe, curved spadix slightly obovoid ovary, prominent style and discoid stigma.

1985 8(1) 14-25 Josef Bogner, S. J. Mayo, C. Sathish Kumar New species and changing concepts in Amorphophallus (Buy)
ABSTRACT: The reduction of Thomsonia Wallich (1830) to the synonymy of Amorphophallus Blume ex Decaisne (1834), nom. cons. is discussed, along with the resultant renaming of Amorphophallus napalensis and Amorphophallus sumawongii. Amorphophallus pendulus is described. Pseudodracontium and Plesmonium are also discussed.

This article available FREE to IAS Members with a PERSONAL login. LOGIN, REGISTER or JOIN
ABSTRACT: After the publication of the new species, Homa/omena speariae Bogner et Moffler (Moffler and Bogner, 1984), I (J.B.) pollinated it by hand obtaining fruits with viable seeds. Seeds were sent to Mr. John Banta of the River Haven Nursery, Rt. 2, Box 144, Alva, Florida 33920, in order to introduce this handsome aroid into the trade. Since our publication, plants were planted into a ground bed at the Munich Botanical Garden where they grew much larger than the original container grown specimens.

1985 8(2) 48-54 Josef Bogner A new Chlorospatha species from Columbia (Buy)
ABSTRACT: Chlorospatha corrugata Bogner et Madison sp. nov. is described.

1985 8(2) 55-63 Josef Bogner Jasarum steyermarkii Bunting (Buy)
ABSTRACT: Jasarum steyermarkii was first discovered by S. and C. Tillett in the Mazaruni River Basin in Guyana on September 24, 1960, but their specimens, although very striking, long remained unidentified. In February 1972, Julian A. Steyermark found the same species in the Estado Bolivar in Venezuela; this collection became the type of the new genus and species, which George S. Bunting published in 1977. The aquatic nature of this aroid is very remarkable because no true aquatic were previously known for the subfamily Colocasioideae. It was certainly one of the most interesting discoveries in Araceae in recent decades.

1987 10(1) 20-22 Thomas B. Croat, Josef Bogner Aroid profile no. 11: Syngonium steyermarkii Croat
This article available FREE to IAS Members with a PERSONAL login. LOGIN, REGISTER or JOIN
ABSTRACT: Syngonium steyermarkii Croat is endemic to the Pacific slope of Guatemala and Southern Mexico at elevations above 1100 m. It was first collected by Dr. Julian Steyermark (Missouri Botanical Garden), who made three sterile collections of the species in three different Departments of Guatemala (Quezaltenango, San Marcos, and Suchitepequez) while collecting for the Field Museum in 1941 and 1942.

1987 10(2) 4-16 Josef Bogner Morphological variation in aroids (Buy)
ABSTRACT: The Araceae or aroid., are a large family of about 2400 species, grouped in 107 genera and these again in nine subfamilies. The aroids are mainly a tropical family and are distributed world-wide. They show great variation in their morphological characters, which will be described in this paper along with some other data.

1987 10(2) 27-30 Josef Bogner A new Typhonium species from Thailand (Buy)
ABSTRACT: Typhonium albispathum Bogner, spec. nov. is described.

1997 20 6-10 Josef Bogner The pollen of Chlorospatha longipoda (K. Krause) Madison (Buy)
ABSTRACT: During routine studies of pollen grains, we came across a peculiarity of pollen formation in Chlorospatha longipoda. Most aroids shed the pollen grains in monads; only two genera, Xanthosoma and Chlorospatha, shed their pollen grains in tetrads. Usually the four pollen grains in a tetrad are arranged tetrahedrally, but Chlorospatha longipoda also has linear tetrads in which the four pollen grains are arranged in a serial sequence.

1999 22 20-29 Josef Bogner, Eduardo G. Gonçalves The genus Gearum N. E. Br. (Araceae: Tribe Spathicarpeae) (Buy)
ABSTRACT: Gearum brasiliense N. E. Br. was first collected in October 1828 by W. J. Burchell. N. E.Brown(1882) gave a very accurate description of the inflorescence and flower structure, although Burchell's specimen was heavily damaged by insect feeding, but until recently this monotypic genus remained incompletely known, due to lack of leaf material definitely attributable to Gearum. Although a second collection of Gearum was made by Burchell (Burchell 8598-leaves only), around the time ofthe holotype gathering, it was not until 150 years later that a third collection was made by Alfeu de Araujo Dias (Vias 41), a Brazilian botanist working for the Projeto RADAMBRASIL.

2000 23 4-7 Josef Bogner Friedrich Hegelmaier (1833-1906) and the Lemnaceae (Buy)
ABSTRACT: The first comprehensive monograph of Lemnaceae, the duckweeds, was written by Christof Friedrich Hegelmaier in 1868. The Lemnaceae were considered by most authors as closely related to the Araceae. Engler (1876) himself included the duckweeds as a subfamily, Lemnoideae, with two tribes in the Araceae, but later as a separate family (Engler, 1889).

2000 23 8-18 Josef Bogner, E. Marchesi Mangonia tweediana Schott (Araceae) (Buy)
ABSTRACT: The genus Mangonia Schott was described in 1857 with one species (M. tweedieana Schott) and later illustrated in his Genera Aroidearum (Schott, 1858). Hicken (1917) described a new genus, Fe/ipponia Hicken, with a single species, Fe/ipponia uruguaya Hicken. Later Hicken (1928) changed the generic name to Felipponiella because his earlier name was a later homonym of a moss genus described by Brotherus in 1912. When one of the authors (Bogner, 1973) studied Felippone's material (Felippone S/-297 and Fe/ippone 5772) it was clearly a second species of Mangonia and thus a separate genus is unnecessary. As circumscribed here the genus Mangonia contains two species. In this paper a comprehensive description of Mangonia tweedieana is presented based on observations made during a visit to Uruguay in 1999. Unfortunately we were unable to recollect M. uruguaya (Hicken) Bogner during the trip in 1999, although it has been very recently recollected at Cerro Largo in the Sierra de Rios. Bogner (1973) published an account of M. uruguaya.

2001 24 3-5 Josef Bogner, J. D. Bastmeijer In Memoriam--H. C .D. de Wit (1909-1999)
This article available FREE to IAS Members with a PERSONAL login. LOGIN, REGISTER or JOIN
ABSTRACT: On 16 March 1999 Professor Dr. Hendrik Cornelius Dirk de Wit died at the age of 89 years. For people interested in aroids he is well known for his revisions of the genera Lagel1Ctnclra and Cryptocoryne.

2001 24 80-93 Josef Bogner, Peter C. Boyce, C.M. Sakuragui A revision of Alloschemone Schott (Araceae: Monstereae) (Buy)
ABSTRACT: The genus Alloschemone Schott is revised. One new species, A. inopinata Bogner & P. C. Boyce, is recognized, and an expanded description of A. occidentalis (Poepp.) Engl. & K. Krause is presented. The distinguishing characters of the genus are discussed, especially with regard to the genus Scindapsus Schott, from which Alloschemone has been considered inseparable. Both genera have unilocular ovaries with basal placentation with one ovule; Alloschemone differs from Scindapsus by a pinnatifid leaf lamina (entire in Scindapsus), shoot architecture, anatomical differences, and Neotropical distribution (Scindapsus Paleotropical). Our new species has fused filaments, a unique character in Monstereae, and further differs from A. occidentalis by the narrower leaf pinnate separated by an oblong sinus. Seeds, often diagnostically very useful in Monstereae, are still unknown in Alloschemone and are highly desirable.

ABSTRACT: Extinct Aroid Acorus brachystachys Heer is synonymized with Nordenskioeldia borealis Heer.

2005 28 3-20 Josef Bogner, M. Hesse Zamioculcadoideae (Buy)
ABSTRACT: Remarkable and distinctive pollen characters support the separation of the tribe Zamioculcadeae as a group distinct from the aperigoniate Aroideae: Recently reported molecular data point in the same direction, and morphological and anatomical data likewise indicate a clear separation. Taken together, the evidence justifies the placement of at least the Zamioculcadeae in a new subfamily, Zamiocu1cadoideae. Zamioculcas and Gonatopus show greater pollen differences from the aperigoniate Aroideae than Stylochaeton, ,which seems to, represent an intermediate transition state. Nevertheless, Stylochaeton is closer palynologically and morphologically to the aperigoniate Aroideae.

2006 29 37-43 Josef Bogner Protarum sechellarum Engl. (Araceae) (Buy)
ABSTRACT: The monotypic genus Protarum is restricted to a few sites in the Seychelles in the Indian Ocean. The history of the single species, Protarum sechellarum Eng!., and its characteristics are described, together with its ecology and future in the wild and in cultivation.

2007 30 49-52 Josef Bogner An additional note on Alloschemone occidentalis (Poepp.) Engl. & Krause (Buy)
ABSTRACT: Images intended to accompany an earlier publication of this species (Bogner, Boyce & Sakuragui, 2001) were lost. Additional material has now been received and images are published here.

2007 30 82-90 Josef Bogner, G. Petersen The chromosome numbers of the aroid genera (Buy)
ABSTRACT: A complete list of the chromosome numbers of the genera of Araceae is given, except for Croatiella E. G. Gonc, a genus recently described. The different chromosome numbers are discussed.

2008 31 3-14 Josef Bogner The genus Bognera Mayo and Nicolson (Araceae) (Buy)
ABSTRACT: The genus Bognera Mayo & Nicolson with its single species Bognera recondita (Madison) Mayo & Nicolson, is described and illustrated and its relationships are discussed in detail. Discussions of its history, discovery, distribution, ecology, pollination, etymology and cultivation are given. The genus Bognera is characterized by its creeping rhizome shoot architecture with two cataphylls preceding each foliage leaf, the last one partly enveloping the petiole (a character unique in the family), the essentially parallel-pinnate venation type (philodendroid) but with third order veins in a clearly reticulate pattern, the unconstricted spathe, the stamens of each male flower connate into a synandrium, the female flowers lacking staminodes, the unilocular ovary with a single anatropous ovule on a basal placenta and the inaperturate pollen grains with smooth (psilate) exine.

2008 31 15-24 Josef Bogner, E. Marchesi Mangonia uruguaya (Hicken) Bogner (Araceae) recollected (Buy)
ABSTRACT: Mangonia uruguaya (Hicken) Bogner has been recollected in Uruguay, where it is endemic. A fuU description and illustrations are given, as well as notes on its history, distribution, etymology and relationship.

2008 31 90-97 Z. Kvacek, Josef Bogner Twenty-million-year-old fruits and seeds of Pistia (Araceae) from central Europe (Buy)
ABSTRACT: First fossil fruits of Pistia (Araceae, Aroideae) are reported from the Early Miocene lignite in North Bohemia. They co-occur with dispersed seeds identified as Pistia sibirica Dorofeev, a morpho-species spread in the Late Oligocene and Early to Middle Miocene deposits of western Eurasia. These fruits remain different only in smaller size from those produced by Pistia stratiotes L., a pantropic floating aquatic aroid and the only extant species of the genus.

2008 31 113 Josef Bogner The chromosome numbers of the aroid genera: An additional note
This article available FREE to IAS Members with a PERSONAL login. LOGIN, REGISTER or JOIN
ABSTRACT: Last year we (Bogner & Petersen, 2007) published a list of the chromosome numbers of the aroid genera, but one genus, Croatiella E. G. Gons,:.(Gons,:alves, 2005), was lacking, because earlier living plants disappeared from cultivation. As expected, Croatiella integrifolia has also a chromosome number of 2n = 34, x = 17

2014 37(1) 44-46 P.M. Resslar, Josef Bogner Using Gibberellic Acid (GA3) to Induce Flowering in Caladium sororium Schott (Araceae)
This article available FREE to IAS Members with a PERSONAL login. LOGIN, REGISTER or JOIN
ABSTRACT: Dormant tubers of an unidentified collection of Caladium Vent. that would not flower in the greenhouse were soaked in a solution of gibberellic acid (GA3) with a concentration of 600 ppm for four hours to induce the formation of inflorescences. Several plants formed inflorescences, and the collection was identified as Caladium sororium Schott.

2014 37(1) 80-88 Walter Lämmler, Josef Bogner Elias Landolt and the Duckweeds (Buy)
ABSTRACT: Elias Landolt was born on July 24, 1926 in Zurich, Switzerland. He read biology at the Swiss Federal Institute of Technology Zurich (ETH: Eidgeno¨ssische Technische Hochschule) where in 1950 he completed his undergraduate work on: ‘‘Synergismen im Bereich von Mikroorganismen’’, and in 1953 graduated with the Ph. D. thesis ‘‘Untersuchungen u¨ber die Artengruppe Ranunculus montanus Willd. in den Alpen und im Jura’’. From 1953 to 1955 he was carrying out postgraduate studies at the Department of Plant Biology of the Carnegie Institution, Stanford University, California (USA), and also at the Earhard Laboratory of the California Institute of Technology (CALTECH) in Pasadena. This was the beginning of his research on duckweeds which resulted in the first publication about the group (Landolt, 1955). His habilitation thesis dealt with physiological and ecological aspects of duckweeds, and the resulting paper was published in 1957. From 1964 to his retirement in 1993 he was tenured professor at Swiss Federal Institute of Technology Zurich (ETH) and from 1966 to 1993 he was also director of the Geobotanical Institute of the same institution. He passed away aged over 86 years on April 1, 2013. (Figs. 1 and 2)
