| Abstract: | Herbarium leaf fragments of the two known species of Orphanodendron (Leguminosae), O. bernalii and O. grandiflorum, were found to contain the quinolizidine alkaloids camoensine (1), camoensidine (2) and guianodendrine (3), supporting the recent phylogenetic placement of the genus in the genistoid clade of subfamily Papilionoideae rather than its traditional placement in subfamily Caesalpinioideae. |
