THE PERENNIAL SCAPOSE DRABAS OF NORTH AMERICA 263 
of leaves: scapes slender, glabrous, about 5 cm. long, naked or with 
one or two small bracts : flowers unknown : fruiting inflorescence race- 
mose, comparatively short (about 2 cm.) : pods 4-7, narrowly lanceo- 
late, flattened, 7-9 mm. long, 2-3 mm. wide: style scarcely i mm. 
long: seeds not winged. 
Dr. Gilg apparently confused D. laevicapsula with D. incerta but 
it seems rather to be associated with D. oligosperma. 
Specimens Examined. — Canada: Rocky Mts., Aug. 1885, Macoun; 
Idaho: summit of Steven's Peak, Coeur D'Alene Mts., Aug. 5, 1895, 
Leiberg, no. 1477 (type in Ry. Mt. Herbarium). Montana: Upper 
Marias Pass, Aug. 3, 1883, Canby, no. 29. 
15. Draba cyclomorpha Payson n. sp. 
Cespitose perennial: leaves clustered on the apices of the many 
branches of the caudex, rounded obovate, fleshy, midnerve indistinct, 
5-6 mm. long, 3-4 mm. broad; pubescence simple, largely confined to 
the leaf margins: scapes leafless, sparingly pilose, 1-2 cm. long: flowers 
unknown: fruiting raceme short and corymbose: pods 3-10, glabrous, 
flattened, typically nearly circular but at times oblong, 4-5 mm. 
broad: style scarcely i mm. long: seeds not winged. 
This species has been confused with D. Lemmoni to which it is in 
fact most nearly related. It differs from that species principally in 
the glabrous, broader pod.

17. Draba asterophora Payson n. sp. 
Loosely cespitose perennial with rather long trailing caudex- 
branches: leaves about i cm. long. 4-5 rnm. wide, obovate to oblanceo- 
late, obtuse, thickish, mid vein obscure; pubescence rather sparse, 
consisting mostly of long stalked, cruciform hairs, simple cilia almost 
entirely wanting; scapes slender, glabrous, 3-4 cm. long; fruiting
