“are distinctly salverform.” However, the corollas of our ma- 
terial collected by Lemmon are no more nearly rotate than those of 
many specimens of other species in this group. Otherwise O. Lem- 
mont seems to be one of many states of the v var. cinerea transitional

te printed label bears this statement, — ‘‘ Narrower-leaved 
form ”’ — A. Gray. It is, probably, only a sand-hill condition, but 
it may be considered as an ecological variety worthy designation on 
account of its very different aspect, caused not only by the long 
narrow leaves but also by the lax-flowered racemes.

This species is unique because of its glabrous stems and lower 
leaf-surfaces.

The description calls for muriculate nutlets but the muriculations 
are usually more or less confluent into transverse rugae. Payson 
writes me that in his judgment these plants are the same species, the 
“‘ yellow corolla-tube ” described for O. paradoxa being merely a 
condition of drying since both collections display the same colora- 
tion, although O. gypsophila was observed to be ‘‘ pure white in the 
field.” Material of O. paradora was not at hand at the time 
O. gypsophila was described.
