2006 29 148-151 Eduardo G. Gonçalves, A. C. D. Maia New evidence of pollination in Gearum brasiliense (Araceae -- Spathicarpeae) (Buy)
ABSTRACT: New evidence is presented to suggest that the monotypic genus Gearum (Araceae) may be truly cantharophilous, not myophilous as suggested before. The credible pollinators in Gearnm brasiliense are large scarab beetles of the species Cyclocepbala celata, which were collected inside floral chambers of inflorescences between the female and the male phases. Along with the direct observations of insects within inflorescences, general floral morphology and construction are used as indirect evidences of a cantharophily pollination syndrome in this aroid genus.

ABSTRACT: The Horto Botaˆnico of Universidade Cato´ lica de Brası´lia (HBUCB) has been a centre for studies on aroids ever since it was established in 2004. In little over eight years it has amassed a comprehensive living aroid collection that now holds 53 genera and 317 species, many of which are only rarely cultivated (e.g. Scaphispatha, Philonotion, Lorenzia, Bognera). The collection also includes an important assemblage of at least 30 accessions that are clones of type material. The access to live specimens in a controlled environment facilitated research on molecular biology, chemical ecology, horticulture and conservation. This article aims to briefly present the Horto Botaˆnico of Universidade Cato´- lica de Brası´lia as a successful case of an active living plant collection in a developing country.
