orl^nnal collection, a fact needing no explanation to one familiar 

 with the topogra[)hy of Santa Fe canon. Tlicre is also an example 

 of this species in the herbarium of Columbia University, under 

 Fcndlcr's no. 43.

Draba patens sp. nov. 



i 



Annual or biennial : stems rather stout, 4 dm. high when ma- 

 ture, branched in the upper three fourths, the branches patent, 

 markedly hirsute with mostly simple hairs, leafy throughout, even 

 on the flowering branches : leaves rather thin, light green, the 

 lowest ones obovatc or spatulatc, about 2.5 cm. long, i cm. wide, 

 petioled, the petioles ciliate ; the others ovate-oblong or ovate- 

 lanceolate, acutisii or the upper ones acute, sessile at the broad 

 base, roughened on both sides with very short hairs, serrate with 

 prominent spreading teeth, these wanting near the ba.se, especially 

 on the leaves of the lower part of the stem ; those on the middle 

 portion of the stem the largest, 3-3,5 cm. long, 1.5 cm. wide; 

 loranches bearing flowers and fruit ha\ing a spread of 15 cm.: 

 calyx yellowish, the lobes oblong, obtuse, 2 mm. long, somewhat 

 pubescent : petals bright yellow, oblong, twice the length of the 

 calyx : fruiting pedicels slender, pubescent, 5 mm. long ; pod 

 twisted, pubescent with short hairs, about i cm. long, tipi)ed with 

 a prominent slender style. 



The type is Professor E. O. Wooton's no. 275, preserved in the 

 herbarium of the New York Botanical Garden. 



This number is cited by Professor Greene as part of his I). 

 TlcIIcnana, but the specimen here described is certainly different 

 from my no. 3669, and from P^Midler's original in the Gray Her- 

 barium. Professor Wooton's plant differs from mine in its system 

 of branching, not being branched directly from the base, as is mine, 

 but the branches commence some distance above the root, and 

 are widely spread, whereas in my plant the upper branches are 

 strict ; the leaf is thinner, broader, of a rather different shape, 

 prominently toothed ; the calyx is smoother, and the pods more 

 pubescent. 



Since writing the above description, I have seen Professor 



Wooto 



of the Mis- 



souri Botanical Garden. This specimen differs considerably in 

 general appearance from the one just described, as it has much 

 larger leaves, which are a little thinner, entire, or almost so. It is 

 a marked form, perhaps worthy of varietal rank.
