The description here given is drawn mainly from the type sheet in Kew 
Herbarium, although certain dimensions, etc., are taken from Johnson 341 
(also at Kew), a sheet with a larger and more matured plant. It may be re- 
marked here that the punctate character noted above for the leaves is to be 
met with in Bidens Taylori and B. Baumii (see below), also a small number 
of other species.
