Phytochemical and biological studies of Gomesa recurva R. Br. (Orchidaceae): Chemotaxonomic significance of the presence of phenanthrenoids

Biochemical Systematics and Ecology, 2018
Abstract The phytochemical study of Gomesa recurva R. Br. (Orchidaceae) allowed the identification of nine compounds, daucosterol (1); the phenanthrenes 3,4,9-trimethoxy-2,5-phenanthrenediol (2); 4-methoxy-2,3,5-phenanthrenetriol (3); 3,4-dimethoxy-2,5-phenanthrenediol (4); 2,4-dimethoxy-3,5-phenanthrenediol (5); the phenolic compounds 3-(4 ...

Psarocolius decumanus(Icteridae) acts as a seedling disperser ofGomesa recurva(Orchidaceae) in the Brazilian Atlantic Forest

Austral Ecology, 2022
AbstractPsarocolius decumanus(crested oropendola) (Icteridae) is a neotropical bird whose reproductive biology is well studied. Its nests consist of pendulous bags up to 2‐m long usually made ofTillandsia usneoides(Bromeliaceae) with dry leaves lining up the incubation chamber.

New additions to Gomesa from old known names (Orchidaceae)

Phytotaxa, 2020
Five new combinations are made for taxa formerly described or assigned to the genus Oncidium, but currently placed in Gomesa. These all predate formerly widely known and accepted names: Gomesa bicornuta, comb. nov. for Gomesa cruciata; Gomesa florida f. florida, comb. nov. for Gomesa longicornu; Gomesa maculosa f. maculosa, comb. nov.

Comparative reproductive biology and pollinator specificity among sympatricGomesa(Orchidaceae: Oncidiinae)

Plant Biology, 2016
AbstractThe incredible pollination mechanisms displayed by orchid flowers has inspired biologists over the centuries. Based on the intriguing flower structures, the relationship among orchid species and their pollinators has been frequently regarded as very specialised.Given that visits on flowers pollinated by oil‐collecting bees are regularly rare ...
