prominent midrib; stipules present, of two or three filiform setae: 
flowers small, yellow, crowded in corymbiform racemes terminating 
the branchlets; pedicels 2-3mm. long, subtended by simple, 
linear, foliar bracts; calyx segments greenish yellow, 1 mm. long, 
lanceolate, weakly bristle-tipped; petals elliptical, thickish, three 
times as long as sepals; stamens exserted; ovary slightly obovate, 
with two ovules in each cell: capsule ovate, 3 mm. long, 2-3 times 
as long as the slender stipe and 4~5 times as long as the persistent 
style; seeds 1 or 2, dark brown, broadly obovate, 2 mm. long. 
Probably most nearly related to C. oocarpa Gray, from which it is easily 
distinguished by the possession of a very short stipe. Collected on dry, loose, 
gypsiferous hillsides near Montrose, alt. 5800 ft., in fruit, October 1912. 
Flowers produced in May and June. No. 222. 
Lupinus crassus, n. sp.—Perennial, caudex branched, forming 
a dense mat from which arise many stems: stems rather stout, 
erect, unbranched, sparsely sericeous, 3-4 dm. high: leaves five 
or six on a stem, green; petioles silky-pubescent, those of lower 
leaves 8-10 cm. long, of upper ones generally longer than the leaflets; 
leaflets 5-10 (usually 7 or 8), thickish, somewhat folded, cuneately 
obovate to oblanceolate, obtuse, silky-pubescent below, upper 
surface glabrate, 3-4cm. long, 10-12 mm. wide: inflorescence 
erect, many-flowered; pedicels 4~5 mm. long, pubescent with short, 
spreading, white hairs; bracts purplish, lanceolate, 1o-12 mm. long, 
exceeding the buds at the apex of the inflorescence and falling by 
the time the flowers are fully expanded: calyx not spurred, densely 
pubescent, lower lip entire, 7-8 mm. long, slightly exceeding the 
bifid upper lip; corolla white, fading brownish, 12 mm. long, dis- 
tance from apices of banner and wings about 6 mm., keel included, 
triangular, acute, scarcely falcate, ciliate except at apex; ovary 
pubescent, ovules 7 or 8. 
This splendid lupine was collected near Naturita, April 21,1914. At this 
time it was not in full bloom. Its habit of growth is peculiar in that it forms 
a dense mat rather than a clump. It seems to prefer soils that are somewhat 
gypsiferous in character and is often found growing on a loose hillside.

Lupinus fulvomaculatus, n. sp.—Perennial: stems nearly gla- 
brous, several to many from a single root, branching upward and
