1978 1(1) 4-10 Simon J. Mayo Aroid-hunting in Bahai (Buy)
ABSTRACT: Despite having been the first area of Brazil to be colonized by the Portuguese, the north-eastern state of Bahia is still poorly-known botanically, particularly in its dry interior region. All the indications are, however, that the flora is very rich, and this applies to the aroids as well as to many other families of plants. Consequently, when in the first three months of 1977 I took part in a Kew expedition to Bahia led by Dr. Raymond Harley, I was particularly keen to refind the many poorly-known Araceae recorded from this region.

1982 5(3) 67-88 Dan H. Nicholson Translation of Engler's classification of Araceae with updating (Buy)
ABSTRACT: When Hooker (1883) was preparing the treatment of Araceae (Aroideae) for the monumental 'Genera Plantarum,' he basically followed the Schottian system, incorporating Engler's (1879) reduction in the number of genera. The first system was "popularized" by Hutchinson (1959) who, with a reversal of the sequence (bisexual genera first), published essentially an English translation of Hooker's latin. Engler (1905-1920), in his monumental 'Das Pflanzenreich', produced his final treatment of the family, including all then known species in nine volumes. This work remains the standard reference for the family as a whole.

1988 11(3) 4-55 Thomas B. Croat Ecology and life forms of Araceae (Buy Back Issue)
ABSTRACT: The most interesting aspect of the family's ecology is the diversity of adaptive life forms. These range from submerged to free-floating, and emergent aquatics to terrestrial plants and to epilithic or epiphytic forms which may be true epiphytes or hemiepiphytic (growing on trees but rooted in soil). Hemiepiphytism is diverse itself, with some species beginning their lives as terrestrial seedlings, then growing skototropically (toward darkness) until they arrive at the nearest suitable tree ( usually a relatively large one which casts a darker shadow) where a physiological change takes place allowing them to grow toward light (Strong & Ray, 1975). They grow as appressed epiphytes on trees or as vines in the canopy. Others begin their lives as true epiphytes, some reconverting to hemiepiphytes by producing long, dangling roots contacting the forest floor below.

ABSTRACT: An overview of the chromosome numbers of the genera of Araceae is given.

1997 20 13-26 Julius O. Boos Observations on New World Araceae--Lasieae (Buy)
ABSTRACT: Three neotropical Lasioids were cultivated and studied over a period of years. Observations were made which add to our knowledge of these poorly studied plants, some previously known only from a few herbarium specimens. Further research is urgently needed both in the lab and field as continuing deforestation seriously threatens the survival of several species in the wild. In addition, the culture of these semi-aquatic plants has proven difficult, and their survival in most collections is normally very short term. Methods for their successful cultivation have been outlined (Boos, 1993) and research continues to improve their long term survival. The genus Urospatba is in urgent need of revision. Two of the three described species of Anapbyllopsis are known only from a Single herbarium sheet.

2005 28 21-31 Eduardo G. Gonçalves A revision of genus Dracontioides Engl. (Araceae) (Buy)
ABSTRACT: The genus Dracontioides was formerly considered monotypic with the only known species (D. desciscens (Schott) Eng!.) restricted to extreme eastern Brazil, growing as a helophytic herb. A second species for the genus (D. salvianii E.G. Gon~.) is here described, also from eastern Brazil (Bahia state). It is a psammophytic herb and a neotenic origin for this species is suggested. Since the last complete description of D. desciscens is the one included in the description of the genus, both species were described, illustrated and compared. Relationship of Dracontioides with genera considered closely related as Dracontium and Anapbyllopsis is discussed, as well as biogeographic and evolutionary trends within the genus Dracontioides and closely related genera.
