MEMOIRS OF THE NEW YORK BOTANICAL GARDEN. l8^ 



villous simple hairs; basal leaf broadly oblanceolate or spatulate, 

 2-4 cm. long, rather thick, generally entire, seldom slightly sin- 

 uate-toothed, sparingly ciliate ; stem-leaves similar but shorter ; 

 pedicels at first short, in fruit about i cm. long, more or less 

 spreading; sepals oblong, fully 2 mm. long, obtuse; petals yel- 

 low, 3-5 mm. long; pod ovate-oblong, 8-10 mm. long and aboiit 4 

 mm. wide, tipped with a style 1.5 mm. long, often somewhat crisped, 

 slightly twisted or curved sideu ays. 



' Draba chrysantha Wats, was based on three specimens, two col- 

 lected in Colorado by Greene and Brandegee and one from Arizona 

 collected by Lemmon. It is evident that it includes more than one 

 species. As Greene's specimens are the ones first cited, they may 

 be taken as the type of the species. These are about 5 cm. high, 

 with erect stems, smaller flowers, and pods which are scarcel}^ 2 mm. 

 wide; the leaves are almost linear and rather thin. Lemmon's 

 specimens are very similar, but much larger, about i dm. high, with 

 narrowly linear-lanceolate leaves 5-6 cm. long; the flowers and 

 the pods are like those of Greene's specimens. Brandegee's speci- 

 mens, on the contrary, have the broad short rather flesh}^ leaves and 

 broad pods described above. Draba crassa grows among rocks on 

 the tops of the higher mountains, at an altitude of 3000-5000 m.
