TURCZANINOW (loc. cit.) based his species Bidens consolidaefolia 
upon Jameson 693 from Quito. At Gray Herbarium is one sheet 
of specimens by JAMESON “from the vicinity of Quito and else- 
where,” and the specimens at the top of the sheet, while lacking a 
number, match precisely the description of B. consolidaefolia. 
It is seen from a study of many specimens of B. humilis collected 
in the last half century, that B. consolidaefolia is merely a slender- 
leaved form of B. humilis and is in no way specifically distinct.

FERNALD (Rhodora 10: 197. 1908) has given an excellent 
discussion of this species. Commonly it occurs with simple 
leaves and then is the var. petiolata (Nutt.) Farwell, but occasion- 
ally it possesses tripartite leaves, matching MUHLENBERG’s original © 
description of the species proper. In July 1913 it was my good 
fortune to be invited to accompany Dr. FERNALD from Cam- 
bridge, Mass., to Winchester, Mass., and there observe the tri- 
_ partite leaves of the typical form, which grows in ¢ | quantity 
' at that place. Tripartite leaves were prcscat on, young plants
