inflorescence shortened with a tendency to become corymbose; pods 
6- 10, broadly lanceolate, 6-8 mm. long, 4 mm. broad, flattened, 
glabrous; style short (about .5 mm. long) but evident: seeds flattened, 
broadly winged. 
D. asterophora is evidently allied to D. Lemmoni and D. cyclomorpha 
as shown by the similar leaves and fruiting racemes. The ranges of 
these three species also are rather close. The stellate hairs and winged 
seed make D. asterophora easily separable. But one specimen has been 
seen and that is from an altitude of 9,000 ft. on Mt. Rose, Washoe 
County, Nevada, Aug. 17, 1905, P. B. Kennedy, no. 11 54 (type 
in Ry. Mt. Herbarium). 
18. Draba Mulfordae Payson n. sp. 
Cespitose perennial: leaves linear or slightly spatulate, obtuse, 
7- 10 mm. long, 1-2 mm. broad, not rigid, midvein obscure often rising 
above the ground on leafy shoots or sobols; pubescence of strong 
marginal cilia and long stalked stellate or branching hairs; scapes 
slender, pubescent, 3-4 cm. long; sepals pubescent, petals white (?), 
about three times as long as the sepals; fruiting inflorescence elongated; 
pods 8-12, lanceolate, 6-8 mm. long, flattened, pubescent; style slender, 
over I mm. long; seeds not winged. 
This plant is rather intermediate between the oligosperma and the 
ventosa group. The linear leaves, strong cilia and elongated raceme 
ally it to the former and the tendency to produce leafy shoots to the 
latter. But one specimen has been seen; it is from Soda Springs, 
Idaho, June 21, 1892, and was collected by A. Isabel Mulford (type 
in Missouri Botanical Garden Herbarium). 
19. D. VENTOSA Gray, Amer. Nat. 8: 212. 1874. 
D. Howellii Watson, Proc. Amer. Acad. 20: 354. 1885. 
D. sobolifera Rydb. Bull. Torrey Club, 30: 251. 1903. 
This seems to be the most variable species of the group. A number 
of varieties might be made separating plants of different localities but 
it seems to be impossible to draw specific lines within the group of 
specimens cited. It should be noted here that the style in D. sobolifera 
is .5 mm. long instead of 5 mm. as the description reads.
