Notes

Miquel () described Besleria surinamensis from Suriname. Pulle () renamed the species as Besleria verrucosa (Splitg. ex de Vriese) Pulle based on Clerodendrum verrucosum Splitg. ex de Vriese (). This species has been identified as Trichanthera gigantea (Humb. & Bonpl.) Nees, a member of the ACANTHACEAE.
A single collection of Besleria lutea L. is labeled "French Guiana". The specimen at P was collected by L.C. Richard, but the locality is doubtful. The specimen was probably collected in the French Antilles where the species is well known.
Leeuwenberg (1958: 369) reported a collection of Besleria lanceolata Urb. in P-LA labeled "French Guiana". Leeuwenberg believed it to have been collected in Martinique where it is endemic.
