I am indebted to Dr. Gray for the larger specimen figured from 
the Paris Herbarium. The separate spike is from Herb. Nuttall. 
Its affinity is with O. Bongardi, B., differing from it in its gemi¬ 
nate spiculse, which are at times compound at base. 
410. C. Jamesii (Torrey); spica subelongata viridi 
purpurea, e spiculis 5-8 cylindricis erectis, masculis 1-4

pallidius, glabrum, sessile, demum deciduum. Achenium r 7 0 lin. 
longum, T 6 -g. lin. latum, fuscum, basi styli sequali apiculatum. 
The specimens I have seen of this species generally accord, 
with the exception of that found by Bigelow, on the Mexican 
Boundary Expedition, which has five spiculse, all male at top. 
Those of Wilkes are the larger, with occasionally more numerous 
spiculse.
