PAYSON—MONOGRAPH OF THE GENUS LESQUERELLA 205 
rosulate tuft; radical leaves obovate or somewhat spatulate, 
entire or few-toothed, tapering to a petiole; cauline leaves ob- 
lanceolate, entire; inflorescence short and dense, hardly more 
than corymbose even in fruit; pods ovate, somewhat compressed, 
tipped with a style of half their own length; ovules about 6 in 
each cell. 
Distribution: Gray, New Mexico. | 
The type of L. valida has not been seen nor have any speci- 
mens that could be referred to it. The ovate, compressed pod, 
as well as the short, dense inflorescence, seems to ally it to L. 
intermedia, with which, indeed, Wooton and Standley associate 
it. The plant is evidently a perennial although the original 
description leaves this in doubt. The root is described as a 
“single tap root." The type was collected at Gray, New Mex- 
ico, by Miss Josephine Skehan in 1898.
