Thave not recognised here the tribe Lysionotew of DC as separate from that of the Aischynanthew. The distinction be- 
tween them is that in the Lysionotex the seed is attached by the lower hair, in Alschynanthee the seed is attached by its lower end and 
all the hairs are free. This distinction is founded by no less an authority than R. Brown ; but as far as I can make out, the seeds in 
Alschynanthus are attached by the lower hair. The distinction is atall events a minute one and troublesome to work with ¢ and IT 
have omitted it as the Indian Lysionotew are sufficiently separated from Alschynanthus by easier characters. 
T have altered also the definition of Dichrotrichum by omitting the very character on which its name is given, viz., the dif- 
ferent color of the two hairs at the two ends of the seeds. This can by itself hardly be thought of generic value and in the Bengal species 
gal s s 
the two hairs are concolorous. 
Mr. Kurz however considers that the species placed here by me (viz., the old Chirita Griffithii) is too remote by its habit to 
be placed in Dichrotrichum : but the alternative is between placing it here for the present or iny 
enting a new genus especially for it. 
Liebigia bracteosa Zollinger probably belongs to the same genus,
