The description here given is drawn mainly from the type sheet in Kew 

 Herbarium, although certain dimensions, etc., are taken from Johnson 541 

 (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. Bourn ii (see below), also a small number 

 of other species.
