CEUCIFER^E. 7 



stellate pubescence, the stem and inflorescence greener, the 

 pubescence more sparse, mostly of forked or 3 -branched 

 hairs, but with some much longer and perfectly simple ones 

 interspersed: cauline leaves lanceolate, serrate-toothed, ses- 

 sile: fruiting raceme loose, with leafy bracts subtending the 

 lower pedicels : flowers small; sepals green, notably bristly- 

 hairy at apex; petals yellow, scarcely twice the length of 

 the sepals: pods erect, short-pedicellate, narrowly elliptical, 

 pubescent on the face with more or less forked and appressed 

 hairs, but the margins quite hirsutulous with mostly simple 

 ones: style short. 



Near the limit of trees, in the mountains near Carson, 

 n. 316. An ally of D. streptocarpa, the pods doubtless more 

 or less twisted when mature. ^ . r . , r 



DRABA NITIDA. Annual, very erect and strict^ simple. ctt; 

 with a few shorter racemes from near the base, the whole 

 plant often 10 to 14 inches high, racemose almost from the 

 base, and, except at base, glabrous, deep-green and shining: 

 leaves in a comparatively small radical tuft, the longest 

 barely an inch long, oblong-lanceolate, obtuse, entire, the 

 outer narrowed at base but hardly petiolate, sparsely sub- 

 stellate-pubescerit, the margins loosely bristly-ciliate; cauline 

 few, oblong-ovate, entire, sessile : pedicels 3 or 4 lines long, 

 ascending, the oblong-linear acutish often somewhat in- 

 curved glabrous pods about as long: flowers small, yellow, 

 the green sepals more or less pilose, as is also the base of 

 the stem: style none. 



Abundant on moist open ground at 10,000 feet above 

 Marshall Pass, 19 July, n. 492. A less luxuriant state of 

 the same was collected, also by Mr. Baker at Cameron Pass, 

 northern Colorado, at 9,800 feet, in July, 1896. The plant 

 is one which has been referred erroneously to D. stenoloba.
