2016 39(2) 71-100 Sin Yeng Wong, Hoe Yin Chen, Peter C. Boyce Studies on Schismatoglottideae (Araceae) of Borneo LIX – A preliminary conspectus of Schismatoglottis Calyptrata Complex Clade species for Sarawak (Buy)
ABSTRACT: A preliminary conspectus of species of the Schismatoglottis Calyptrata Complex Clade for Sarawak is presented. Six species are accepted, of which Schismatoglottis baangongensis S.Y. Wong, Y.C. Hoe & P.C. Boyce is newly described, and S. muluensis M. Hotta is resurrected from within S. calyptrata (Roxb.) Zoll. & Moritzi. Current evidence does not support the presence of Schismatoglottis calyptrata sens. strict. in Sarawak, while occurrence on Borneo as a whole is questionable. A modified description of S. calyptrata, excluding characteristics of Bornean taxa hitherto included in synonymy is provided. An identification key to the accepted species for Sarawak is provided, and most are illustrated from living plants.

2016 39(2) 101-120 Peter C. Boyce, A. Haigh Rhaphidophora bogneri (Araceae: Monsteroideae: Monstereae) a new species from West Africa, and notes on the Rhaphidophora africana Complex (Buy)
ABSTRACT: Rhaphidophora bogneri P. C. Boyce & Haigh is described as a new species from Gabon, equatorial West Africa, defined by inflorescences pendent during anthesis and fruiting. Rhaphidophora is additionally reviewed for Africa and three described species are accepted, of which R. africana N. E. Br. is considered undoubtedly polyphyletic, likely encompassing upwards of four species of which at least three are considered to be taxonomic novelties. Unfortunately, available preserved collections coupled with political circumstances prevailing throughout much of the species’ geographical range currently make a proper taxonomic treatment impossible. Rhaphidophora ovoidea A. Chev., described from fragmentary material from basalts, is treated as inadequately known. Rhaphidophora bogneri is illustrated from cultivated living plants, all described species are also illustrated from their nomenclatural types. The three accepted African Rhaphidophora species are delineated with a key.

2016 39(2) 121-125 Peter C. Boyce, Sin Yeng Wong Studies on Homalomeneae (Araceae) of Sumatera V – Homalomena squamis-draconis, a new species for the Chamaecladon Clade (Buy)
ABSTRACT: Homalomena squamis-draconis, a highly ornamental new dwarf species of Chamaecladon clade, is described and illustrated from Sumatera.

2016 39(2) 126 Thomas B. Croat, M. Marcela Mora Philodendron apiculatum Croat & M.M. Mora, nomen novum (Araceae)
This article available FREE to IAS Members with a PERSONAL login. LOGIN, REGISTER or JOIN
ABSTRACT: In a recent article (Croat et al., 2016) a new species from Ecuador was described as Philodendron ellipticum. Later, however, it was discovered by the second author that this name was already occupied by a different species described by Engler (1905). For this reason we are providing a substitute name for the homonym Philodendron ellipticum Croat.

2016 39(2) 127-133 Julio Andrés Sierra-Giraldo, A. Lorena Hernandez-G, Monica M. Carlsen New distribution record for Anthurium zuluagae Croat (Araceae) in Colombia (Buy)
ABSTRACT: Anthurium zuluagae is recorded in the municipality of Gachalá (Department of Cundinamarca), in the Colombian Eastern Cordillera. This new record expands its distribution area in Colombia. Anthurium zuluagae is an uncommon and poorly known species. Therefore, more research on its population status and ecological characteristics, such as type of pollinators and dispersers, is needed as well as to understand the distribution patterns of the Colombian aroids particularly in the Eastern Cordillera.

2016 39(2) 134-186 Thomas B. Croat, O.O. Ortiz A Reappraisal of the Anthurium cuspidatum Masters Complex, section Polyneurium (Araceae) (Buy Back Issue)
ABSTRACT: A realignment is made in the circumscription of Anthurium cuspidatum Mast. which has for many years been interpreted as being plants with reddish brown, moderately elongated blades with usually well-developed posterior lobes in contrast to typically green-drying blades which are more broadly ovate and have the basal veins more nearly free to the base. A study of the type specimen of Anthurium cuspidatum shows it to be a plant with broadly ovate green-drying blades with the basal veins nearly free to the base whereas the more narrowly ovate reddish browndrying plants long considered A. cuspidatum have proven to represent four different species: A. talamancae Engl. with leaves more than two times longer than wide and with up to five pairs of basal veins, A. intactum Croat & O. Ortiz sp. nov. with leaf blades less than two times longer than broad with six or more pairs of basal veins, A. christeliae Croat & O. Ortiz sp. nov. with leaf blades attenuated at base and A. palosecense Croat & O. Ortiz sp. nov. with leaf blades rounded to subcordate at base with few basal veins (1–2 pairs). Anthurium propinquum Sodiro var. albispadix Croat & J. Rodr., long considered to be a member of the A. cuspidatum complex and initially considered to be a variety of A. propinquum Sodiro (now a synonym of A. cuspidatum as treated here) is now considered to be distinct at the species level and is here elevated to the species level as Anthurium albispadix (Croat & J. Rodr.) Croat & O. Ortiz. Another close relative to Anthurium talamancae is A. monticola Engl. which is reported for the first time from Panama and included in the key.

2016 39(3) 4-22 Marc Gibernau Pollinators and Visitors of Aroid Inflorescences III - Phylogenetic & Chemical insights. (Buy)
ABSTRACT: This update on aroid pollinators or inflorescence-visitors adds information on 32 genera (and 60 species). Of these, 10 aroid genera and about 36 species are newly documented or revisited under new generic names. In summary, currently available data on the subject now sums up to approximately 200 aroid species across 67 genera. An ever increasing number of studies now aim at establishing the identity of effective pollinating insects among all the visitors, but also at understanding how other florivorous or phytophagous insects can affect the plant reproductive success. In recent years, many studies have integrated molecular and/or chemical data to the study of aroid pollination. Such multidisciplinary approaches further increase our knowledge of the functional and evolutionary processes involved. Aroid-insect interactions are far more complex than just plant-pollinator relationships, they include in many cases non-mutualistic partners taking advantage of the interaction to carry on with their biological cycles. Hence interactions between these plants and their inflorescence visitors are subjected to multiple selective pressures, which ultimately drive the evolution of the component parts and the whole.

2016 39(3) 27 William Rotolante My Adventures in Anthurium Breeding
This article available FREE to IAS Members with a PERSONAL login. LOGIN, REGISTER or JOIN
ABSTRACT: Anthurium is the largest genus of Araceae. They vary from the beautiful colored spathes of Calomystrium group noted for their large colorful spathes to the giant bird’s nest Pachyneurium group with their huge elliptical leaves and the Cardiolonchium group with their large velvety, colorful heart-shaped leaves (there are more groups but these are some of the interesting ones with which I have worked). The genus is so far-ranging in looks that it is hard to tell some anthuriums are even related to others in the genus. Anthuriums range from Argentina all the way up to Mexico and Caribbean islands. Because of the different ranges and ecosystems in which they evolved, they have adapted to a lot of different growing conditions. Some like lots of water and some like dryer conditions. Some like lots of light and some like to be in the shade. Some like cooler weather and some like it hot.
