108 Muhlenbergia, Volume 6 



long, caducous: pedicels 7 mm. long, densely pubescent: calyx 

 pubescent with spreading hairs, 10 mm. long, the lobes nearly 

 equal, the upper cleft nearly to the base, the divisions lanceo- 

 late, acute, standing well apart; lower lobe lanceolate, minutely 

 3-toothed, 2 mm. wide at base; a subulate bractlet 2 mm. long 

 at the base of the calyx on either side: flowers violet-purple, 

 12 mm. long, 7 mm. deep, distance between apices of banner and 

 wings 5 mm.; banner with the edges slightly turned back but 

 not parallel, forming a broad scoop-shaped body viewed from 

 the rear, the upper part of the face short and broad, whitish, 

 with a narrow purple dotted groove, the lower two-thirds con- 

 cealed by the wings, the groove here broad (2.5 mm. wide), with 

 a rounded process or callosity on either side at the elbow, glab- 

 rous dorsally; wings apparently a little shorter than the banner, 

 4 mm. broad and as deep, the lower edges open only under the 

 calyx, the upper edges covered for two-thirds of their length by 

 the face of the banner, which fits into a broad and rather deep 

 depression: keel glabrous, strongly curved, 3 mm. deep at the 

 middle, the attenuate apex purple. 



The type, in the herbarium of the Nevada Agricultural 

 Experiment Station, is my no. 9588, collected May 1, 1909, at 

 Truckee Pass, Washoe county, Nevada, elevation about 4400 

 feet, growing among sage bru.sh in the narrow valley along the 

 Truckee river. Il is rather common in the vicinity of Reno, 

 for I have since found it on Peavine at about 6000 feet, on the 

 ridges above Verdi, and on the hills along the Truckee three or 

 four miles above Reno. At the higher elevations it does not 

 grow so tall as at the type station. It is a handsome species 

 when fresh, but the flowers, especially the banner, are inclined 

 to fade if neglected in drying. 



Specimens were sent to the Gray Herbarium last winter 

 and reported upon by Miss Eastwood, who informed me that she 

 could not identify them with any specie- there. The only plant 

 known to me tli.it Wears a general resemblance to this species is 

 an undetermined one collected at the Dalles and near Biggs, 

 I Oregon, on the Columbia river, but that has different floral char- 

 acters It is perhaps related to /.. sericeus Pnrsh.
