10 SYNOPSIS OF THE FLORA OF COLORADO. 



ly elongated, 4'-5' long; pedicels divaricate, 6" long; petals scarcely 

 exceeding the calyx; siliques slender, 2' long, widely spreading; on 

 very short stipes ; seeds oblong, emarginate. Canon City, Brandegee. 

 Webster Canon, Eedfield. 



CAMELINA SATIVA, Crantz. Greene. On the road from Denver to 

 Idaho Springs, Porter. Introduced. 



LEPIDIUM INTERMEDIUM, Gr. Porter. Weston's Pass, July 18, 

 Coulter. Denver, Eedfield. This species shows considerable variation. 

 Apetalous states are not uncommon; one form from the neighborhood of 

 Denver has such slender, delicate racemes and small pods, that if the 

 pods were oval and not orbicular, it could be safely referred to L. rude- 

 rale, L. Denver, Dr Smith. Canon City, Brandegee. 



LEPIDIUM ALYSSOIDES, Gr. PL Fendl., p. 10. Annual, glabrous, 6' to 

 12' high; stems diffuse, corymbose-racemose; branches minutely puber- 

 ulent; leaves narrowly linear, mucronulate, attenuate at base, very eu- 

 tire, lJ 7 -2 7 [long, l"-2" wide, lowest often piimately 3-5 lobed ; ra- 

 cemes dense, corymbose; petals round-spatulate, thrice longer than 

 the calyx; stamens 6; silicles ovate, wingless, scarcely emargiuate, 

 glabrous; style very short, but thrice the length of the minute emar- 

 gination. South Park, July, Porter. Near Pueblo, Greene; Eedfield. 



LEPIDIUM MONTANUM, Nutt. Nearly glabrous, decumbent ; branches 

 many from a long, somewhat woody root, 8' to 12', spreading in a cir- 

 cular manner; radical leaves usually more or less bi-pinnatitid, seg- 

 ments short, acute, upper leaves trifid or entire ; flowers rather con- 

 spicuous, sepals oval-oblong ; petals nearly twice as long as the sepals; 

 style conspicuous; silicles 2" long, indistinctly reticulated, elliptical, 

 slightly emarginate, wingless; pedicels 3" -4" long; cotyledons incum- 

 bent. South Park, Canby ; Porter. 



LEPIDIUM SATIVUM, L. Near Denver, Dr. Smith. Introduced. Dis- 

 tinguished by its larger, ovate, winged pods, slightly notched at the top. 



THLASPI ALPESTRE, L. (?) Perennial, glabrous; stems ascending, 3'- 

 12' high, simple ; radical leaves petioled, ovate or obovate, entire or 

 denticulate, cauline ovate-oblong, cordate, clasping ; racemes crowded, 

 or usually elongated and loose, %'-& long; flowers rather large, petals 

 l/'-S" long; pods 2 /A -4" long, acutely margined but not winged, short- 

 oblong, cuueate at base, emarginate, truncate or rounded at the apex, 

 4-8 seeded; style J"-!" long. We have followed Watson (in King's 

 Rep., vol. 5, p. 31) in naming this plant, which is usually referred to 

 T. cochleariforme, DC. Alpine and subalpine ; frequent. Hall & Har- 

 bour, 46; Meelian ; Brandegee; Coulter. Gray's Peak at 11,500 feet, 

 Eedfield. 



CAPP ARID ACE 2E. 



CLEOME 1 INTEGRIFOLIA, T. & G. Annual, somewhat glaucous, 2-3 

 high, widely branching; leaves 3-foliolate ; leaflets lanceolate (the lower- 

 most oblong) entire, submucrouate ; racemes sometimes nearly 1 long ; 

 flowers large, showy, reddish purple, rarely white ; sepals united to 

 the middle, persistent ; segments triangular-acuminate; petals with 

 very short claws; stamens equal; pods oblong-linear, compressed, 

 much longer than the stipe. Ou water-courses along the foot-hills -and 



1 CLEOME, L. Sepals distinct or somewhat united. Stamens 6 or rarely 4. Torus 

 minute. Pod linear or oblong, subsessile or stipilate. Annual herbs or shrubs, with 

 digitate or simple leaves 'and racemed or solitary flowers. Bcntli. $ Hook.
