ENUMERATIO SPECIERUM. 
Subgen. 1. EUTRACHELOSPERMUM K. Schumann in Engler & Prantl, 
Natürl. Pflanzenfam. IV. Abt. 2, 173 (pro sectione) (1895). : 
The principal differences of the four subgenera are briefly stated in the key. 
ey are found in the structure of the flowers and of the fruits, while in the inflo- 
Tescences there are only slight differences. The seeds of Eutrachelospermum are 
more or less angular-cylindrie with a furrow, while they are broader and flatter in 
the two other subgenera. The angle in which the follicles diverge seems to be 
rather variable in the first subgenus, and the fruits and seeds of species No. 1-7 need 
further investigation.
