Carex owyheensis, n. sp.—Plants wholly glabrous, single or in 
small tufts from cormlike rootstocks with an abundance of fibrous 
roots: culm rather slender, inconspicuously striate, 3-5 dm. high: 
leaves bright green, few to several, mostly basal with one near the 
middle of the culm and one or two foliar bracts above, rather short 
and broad (5-15 cm. long and 6-12 mm. broad), flat, often with 
acute involute apex: spikes 3-5, in a capitate terminal cluster, 
and with one or two more or less remote spikes in the axils of foliar 
bracts, 12-22 mm. long; the bracts of the terminal cluster from 
lance-acuminate to broadly ovate and obtuse; terminal spike stami- 
nate above only: stigmas 3; perigynium membranous, not strongly 
nerved, narrowly ovate, tapering gradually into the beak which is 
shorter than the body, pale green with small reddish brown dots 
below and with the two short, rather soft teeth of the beak dark 
reddish brown, about 5mm. long; scale ovate-oblong, obtuse, 
thin, the pale green center one-nerved, the margins dark reddish 
brown, much shorter than the perigynium: achene trigonous-ovoid. 
This is probably nearest to C. Raynoldsii Dew. as regards the technical 
characters, but in the color and in the grouping of the terminal spikes it is 
suggestive of C. viridis Dew. and C. multinoda Bailey. It was secured by 
Macsrive at Silver City, in the Owyhee Mountains, in marshy ground, July 
20, IQIO, nO. 442. 
Calochortus cyaneus, n. sp.—Glabrous and somewhat glaucous, 
rather slender, 3-4 dm. high: bulb small, ovate to oblong, more or 
less covered with dead flaky scales as is also the base of the nearly 
straight stem: leaves 3-5, including the 1 or 2 floral ones, narrowly 
linear, involute, somewhat expanded at the sheathing base, 6-10 cm. 
* The first paper dealing with the collections of Mr. J. Francis MACBRIDE In 
Idaho appeared in Bor. Gaz. 52: 261-274. 1911, where there is also a brief outline of 
the field work and the field covered.
