MUNZ AND JOHNSTON: PLANTS OF SOUTHERN CALIFOPNIA 301 
That species differs, however, in having usually a larger corolla 
with different proportions and a lighter shade of blue and has 
3 small blue spots along the faucal edge of the lower lip, in ad- 
dition to having more developed, straight, strongly divergent 
upper corolla-lobes, a less developed corolla-tube, an evidently 
exserted stamineal tube, divergent aie and a distinct north- 
ern range. . 
The only material of true D. pulchella studied from Southern 
California is the specimen in the Gray Herbarium collected by 
J. G. Cooper in “wet ground” on the ‘‘ Upper Mojave River ?.” 
From this station and others in San Luis Obispo County, it 
ranges northward through the state. It is not improbable that 
D. immaculata is the same as D. pulchella var. arcana Jepson 
(Madrofia 1: 100. 1922), a variety based upon material col- 
lected at La Mesa, San Diego County. Since both D. immacu- 
lata and D. concolor occur in that vicinity and are equally well 
covered by Jepson’s brief description, we are basing our D. im- 
maculata upon material which we know to be characteristic of 
the concept we have in mind, rather than forming a binomial 
based upon Jepson’s trinomial.
