WEST AMERICAN ASPERIFOLLE. 115 
20. C. ECHINELLA. A span high, with a few ascending and 
stoutish branches from the base : moderately pilose-hispid : 
spikes terminating the branches and branchlets, rather short, 
biserial: calyx 2 lines long, the segments attenuate above, 
erect: nutlets a line long, broadly ovate, acute, light gray, 
their whole surface densely covered with minute but well 
elevated and very sharp-pointed murieulations ; groove ap- 
parently either open or elosed, the basal forks of which, not 
divarieate but only moderately divergent, are abways closed. 
Mt. Stanford, above Donner Lake, 1886, Mr. Sonne. Ex- 
tremely well marked in the murieation of the nutlets. In 
habit like some Oregon plants which I refer to C. ambigua, 
but whieh are likely to prove the type of another unnamed 
species.

Cal. Acad. i. 208. —Apparently of this genus, although suffru- 
tescent while all the rest are annual The conspicuously 
pedicellate calyx is deciduous when ripe, by a joint at its 
very base, the pedicel remaining on the rachis. The species 
is surely a connecting link between Cryptanthe and Oreocar ja, 
and many draw the latter genus into this, if in Oreocarya, 
calyces in maturity are in any cases deciduous (as I have 
now reason to suspect), unless it may stand on habit alone. 
+ + Nutlets smooth and shining, light grey, or mottled with 
dark brown, 
++ solitary, or rarely two, the others abortive.
