64 ERYTHEA. 
toward the base: flowers rose-red: stamens long-exserted: 
calyx-lobes deltoid-ovate, erect in fruit: follicles glabrous 
and shining. 
At subalpine elevations of the Sierra Nevada, Calif., and 
northward; often forming thickets or natural hedgerows two 
or three feet high. 
Eryngium alismefolium. Perennial, with a fascicle 
of very few coarse roots: radical leaves a foot long or 
more, jointed and rush-like, with no blade; the lowest cauline 
similar though with a small entire or spinose-toothed blade, 
and usually one or more spines at the joints of the long 
petiole: stem solitary, parted almost at base into 3 or more 
slender repeatedly dichotomous branches, but the whole not 
equalling the radical and lower cauline leaves: heads barely 
inch high, short-peduncled or sessile: bracts not numerous, 
subulate-lanceolate, mostly spinose-toothed; bractlets oblong- 
ovate, the scarious margin with a few teeth or entire, apex 
spinose-cuspidate, little exceeding the flowers: calyx-lobes 
oblong-ovate, spinose-tipped, not equalling the styles. 
Collected at Egg Lake, Modoc Co., Calif., 25 Aug., 1894, by 
Baker & Nutting. 
Sanicula divaricata. Perennial root long and deep- 
seated, simple, slender and cylindrical: stem solitary, stout- 
ish, erect, flexuous, a foot high or less: radical leaves few, 
biternately or triternately divided, the primary divisions 
petiolulate or subsessile, parted into obovate cleft or coarsely 
toothed segments; cauline leaves small and subsessile, each 
with a long spreading peduncle in its axil, this with an invo- 
lucrate 3-to 5-rayed umbel: flowers greenish: fruits with 
long uncinate-tipped prickles from an abruptly pustulate- 
swollen base. 
Collected by the author, near Castle Peak, above Donner 
Lake in the Californian Sierra, 20 July, 1893. Specimens of 
this excellent species may be found in herbaria under the 
wrong name of S. Nevadensis; the type of that being a very 
different stout, low, diffuse, acaulescent, plant.
