960 DIADELPHIA DECANDRIA, Crotalaria. 
small. Racemes terminal, single. Bracées oval, one-flower- 
ed. Flowers numerous, papilionaceous, large, of a beautiful 
bright yellow. Calyz bilabiate ; the upper lip two-cleft; the 
under one three-parted in the middle, and there gaping; at 
the apex the segments are united. Banner obtuse, erect. 
Wings oblong, obtuse. Keel much pointed, slightly twisted 
at the apex and closely shut. Filaments, their lower half — 
united into one body, with a fissure down the upper side, 
which has a circular gape at the base ; extremities free, and 
alternately shorter. Anthers on the shorter filaments linear, 
on the longer ovate, and two-lobed.* Legumes sessile, club- 
shaped, downy, from one to two inches long. Seeds numer- — 
ous, kidney-formed, 
This plant yields the natives their best hemp, for they have 
no idea of the quality of the bark of the common hemp plant, 
Cannabis, which is indigenous in every part of India; the — 
leaves and flowers thereof being the only parts used by them. 
These they employ as an intoxicating, narcotic drug, and a 
most powerful one it is. 
* There is something very interesting in those two sorts of sta- 
mens. Ifa flower is opened sometime before the natural time of 
its expanding, which must be just before any of the anthers burst, 
the filaments of the subulate set will then be found considerably 
longer than those of the round set, and the stigma will then be 
3 about the same height ; these long anthers come to maturity long 
before the round ones, and about. the time the stigma is among 
them ; but the style continues to grow longer, by which means the 
bearded ‘stigma pushes on with it much of the pollen from the long 
anthers whose filaments do not now lengthen any more ; but those 
of the round ones now begin to lengthen, pushing their anthers 
considerably beyond the apices of the linear set, and even with 
the stigma, by this economy they come in contact with it before or 
about the time of their maturity. These changes r segue found 
most conspicuous in Crotalaria juncea and pent , whose 
flowers are very — at being nly son with thenake
