Hooker fl. bor. t. 47. Th. oregonensis Dec — ; 
leaves petiolate rhomboida! silky beneath, sti- 
pules rounded foliaceous, raceme subsessile in- 
terrupted — Missouri and Origon, my specimens 
are from Bradburry, roots creeping, stems pe- 
dal angular. 
This will conclude our Leguminose plants of 
Sophora tribe, the Virgilia is a tree and my 
N, G. Cladrastis, the Soph, sericea is subdia- 
delphous forming my N. G. Vexibia. I shall 
now give another interesting monograph of our 
Crotalarias 
244. CROTALARXA. Linneus had only 23 
sp. we have now about 150 ! but many hetero- 
genous sp. are blended even by Decandole, see 
my flora telluriana for N. G. meantime most of 
our N. American sp. form a very natural group; 
our Authors have only 5 mostly deemed var. of 
C. sagittalis by Mx. some ascertained by Pursh 
and Elliott, but misnamed, since sagittalis , le- 
vigata and parvijlora are exotic plants. I 
shall revise them and increase to 10 sp. having 
all simple leaves and long peduncles opposite to 
leaves, bracteate commonly multiflore, stem 
often winged by decurrent stipules, like a re- 
versed arrow, mostly annuals, flowers bi brac- 
teate yellow estival. They must form a sub- 
genus locaulon (arrow stem) with the similar 
kinds of South America &c.

deeply 5fid subequal subbilabiate, equal to pe- 
tals papil. Vexillum obcordate reflexed, keel 
acuminate longer than wings, stamens 10 mo- 
nadelphous at base, split behind, filaments al- 
ternate longer bearing 5 round anthers com-
