^ Draba saxosa n. sp. Anstruther Davidson, M.D. 



Many branched perennial 12 cm. high, leaves crowded at the base, 

 leaves oblanceolate, entire, stellately pubescent, narrowing to a peti- 

 ole-like base, 20 mm. long, 4 mm. wide; stems loosely pubescent and 

 without leaves; petals yellow, lanceolate, rounded at the apex, slight- 

 ly exceeding the sepals; stamens exserted; pedicels curved or re- 

 curved one half the length of the pod; pods twisted, 10 mm. long, 

 2.5 mm. wide, awn 2 mm. long, pods broadest near the base. 



California: Summit of St. San Jacinto; July 11, 1896. Type in 

 author's herbarium. 



This plant has passed as D. corrugata Wats, and has been so iden- 

 tified by Dr. Hall in his "Botanical Survey of San Jacinto Moun- 

 tains," but it differs from D. corrugata the type specimens of which 

 came from Mt. Greyback. In the latter the flowering stems are very 

 much branched and leafy. In D. saxosa the stems are simple and 

 quite devoid of leaves, the pods are more twisted and the pedicels 

 curve so as to form a unilateral appearing spike. The pedicels in 

 D. corrugata are straight and upright and the whole plant is more 

 densely pubescent. 

 K Hutchinsia Californica n. sp. 



Slender many branched annual 15 cm. high; basal leaves orbicular 

 or oblanceolate, short petioled; cauline leaves oblanceolate, entire or 

 with 1 or 2 acute lobes; pods elliptic, 3-4 mm. long; whole plant glab- 

 rous. 



CaHfornia: Del Sur, Mohave Desert, May 12, 1893. Not un- 

 common in subalkaline spots in the Mohave Desert and north to 

 Inyo County. 



This is the desert representative of H. procumbens (L.) Desv. and 

 differs from the maritime species in being wholly glabrous with mostly 

 entire leaves and a slightly longer and more elliptical pod. 

 ■^ The Nodose Hairs on Lupines. 



In a note appended to the description of L. subhirsutus in the last 

 Bulletin attention was drawn to the nodose hairs on one species. 

 These nodose hairs are limited to a few species and have in conse- 

 quence a distinct diagnostic value. 



Examination of the material in my herbarium shows that while a 

 few of the following species show slightly nodose hairs on the calyx 

 the only species showing this nodose character on the foliage are: — 

 L. sparsijlorus ; L. concinnus ; L. alpinus. In the latter the nodes are 

 more minute. The following show no nodose hairs on stem or foliage: 

 L. af finis; truncatus; hirsutissmus ; Chamissonis ; formosus ; Bridg- 

 esii; densiflorus ; odoratus ; superba; Inyoensis ; micanthus ; Stiveri; 

 Grayii; Breweri. 



L conjertus and L. elatius show some minute nodes. The latter is 

 probably the same species as L. Inyoensis Heller, the leaves are more 

 silky but in other respects they are alike. 



Specimens of L. Inyoensis gathered at Bishop Creek, alt. 9000 ft., 

 are somewhat silky but this becomes less and less apparent as the alti-
