THE PERENNIAL SCAPOSE DRABAS OF NORTH AMERICA 265 
Tate Mine, Marysvale, Aug. 28, 1894, Jones, no. 5936 (type no. of 
D. sobolifera Rydb.); Delano Peak, July 26, 1905, Rydherg &' Carlton, 
no. 7231; near Beaver, June 7, 1913, H. Redeker, no. 50. Wyoming: 
High Peak between Snake River and Wind River Valleys, 1873, 
Parry (type no. of D. ventosa). 
20. Draba cruciata Payson n. sp. 
Cespitose perennial ; caudex-branches slender; leaves oblanceolate, 
usually toothed, thickish, midnerve obscure, 7-10 mm. long, 2-3 mm. 
broad, acute or acutish; pubescence stellate, each hair usually bearing 
four arms, ciliae wanting or inconspicuous; scapes slender, 5-7 cm. 
long: sepals yellow, glabrous or pubescent; petals yellow, about three 
times as long as sepals: fruiting raceme elongated: pods narrowly 
lanceolate, 7-9 mm. long, 2 mm. broad, glabrous or simply pubescent, 
flattened: style slender, i mm. long; seeds not winged. 
The relationship of this plant is not at all evident. Hall suggests 
that it is near D. Lemmoni and if it is, it should be placed with D. 
asterophora on account of the branched cruciform pubescence. The 
slightly toothed leaves are a most interesting development. Cali- 
fornia: Vicinity of Mineral King, Tulare Co., July 10, 1904, Hall & 
Bahcock, no. 5361 (type in Ry. Mt. Herbarium). 
21. D. UNCiNALis Rydb. Bull. Torrey Club 30: 251. 1903. 
I have seen no specimens of this species. 
Type Locality. — Tate Mine, Marysvale, Utah. 
22. Draba sphaeroides Payson n. sp. 
Loosely cespitose perennial; caudex much branched: leaves clus- 
tered on the apices of the caudex-branches, narrowly spatulate, obtuse, 
green, 3-5 mm. long; pubescence rather long, ciliate and branching, 
but few truly stellate hairs present: scapes naked, slender, sparingly 
pubescent with branched or stellate hairs, 1-1.5 cm. long: sepals 
glabrous or sparingly pubescent; petals yellow, twice as long as the 
sepals: fruiting inflorescence racemose, 1.5-2 cm. long: pods 6-12, 
glabrous, ovoid, scarcely flattened, 3-4 mm. long; style slender, about 
I mm. long. 
Plants with globose pods are more or less anomalous in this genus 
but in aspect and all other characters this plant is so obviously a 
Draba that no one would think of placing it elsewhere. Its affinities 
are doubtless with D. oligosperma. Collected above receding snow at 
an altitude of 10,800 ft. on Jarbidge Peak, Nevada, July 8, 1912, 
Nelson & Macbride, no. 1981 (type in Ry. Mt. Herbarium).
