76 ILLUSTRATIONS OF INDIAN BOTANY. 
The determination of the species of the genus Preraspermum, is an undertaking of consi- 
derable difficulty, owing to the great variations in the form of the foliage in different specimens 
of the same species. In my recent excursions I have added a new species to this genus, and 
have reason to suspect that there are several, yet unknown to us, to be met with in our alpine 
jungles. I had not the good fortune to find fructification of some that I consider new, and can- 
not in consequence describe them, but their trailing arborious habit, leave little reason to doubt 
their being different from all those already described. 
ydia. a genus established by Dr. Roxburgh, and so called in honor of the late Colonel 
Kyd, the founder of the Calcutta Botanic Garden, consists of fine shrubs, bearing their nu- 
species in Ceylon, to which Dr. Arnott has given the name of K. angustifolia, a peculiarity by 
which it is well distinguished from the continental forms which have the leaves nearly round. 
ther two genera are characterized in our Prodromu; as belonging to the order, namely, 
Eriochlena and Microchlena. At the time of publication we expressed a doubt of the stability 
of both these genera, conceiving that the characters assigned by DeCandolle were insufficient. 
to. keep them distinct. Of the justice of these doubts further observation has not only satisfied 
me, but have even led me to doubt, whether two plants described in our Prodromus under these 
names form more than one species, indeed I feel almost certain that they do not, and ought 
to be united. ‘These genera are made to rest on the circumstance of one having a quinary the 
other a quaternary series of pee a difference of every day occurrence in different specimens 
of course more likely to occur when taken from different trees, 
though of the same species. The following are the new genera of Sterculiee proposed by
