Cryptanthe ramosissima, while the island plants are named K. or C. 
maritima. They vary much in habit, apparently being able to 
adapt themselves to very diverse conditions. All the forms that 
I possess have one peculiarity that separates them sharply from 
all other species of Cryptanthe, even from C. Cedrosensis, namely, 
they have only two ovules! The numerous specimens examined 
range in habitat from Inyo county, the Mohave and Colorado 
deserts, to northern Lower California and Lagoon head, and the 
many islands off the coast of Upper and Lower California from 
Santa Catalina to Santa Margarita. 
Penstemon floridus, n. sp.—Glabrous and glandless, 3-4" 
high: leaves thin-coriaceous, 5—7™ long, ovate-lanceolate, sessile, 
acutely spinulose dentate or the smaller oblong and _short- 
petioled, none connate-perfoliate: thyrsus virgate, 3°" long; 
peduncles and pedicels 1-2 long or shorter: corolla rose- 
purple, 2-2.5™ long: sepals ovate-acuminate, 4"" long; the tube of 
the corolla two to three times as long, then dilated into a ventri- 
cose throat and slightly contracted at the mouth, lobes some- 
what spreading: sterile filament glabrous; anthers explanate: 
capsule three times as long as the sepals, broadly ovate: seeds 
black, irregular in form, obtusely angled, rugose and granular. 
Mt. Magruder, Nevada, Dr. C. A. Purpus, no. 5928. 
This plant is nearly related to P. spectabilis, a species given that name by 
Dr. Thurber, who collected it in southern California. Dr. Gray included 
with it plants from the Interior Basin, but the above described species seems 
to be quite distinct. Some of the differences between it and P. spectadzilis 
are the absence of connate-perfoliate leaves, the more virgate thyrsus, the 
corollas with somewhat constricted mouth and short lobes not widely spread- 
ing. VP. sfectabilis is a common species of western San Diego county, Cali- 
fornia. 
Pentstemon incertus, n. sp.—Suffrutescent, 3-4" high, much 
branched from the base, glabrous excepting the slightly glandular 
peduncles and pedicels: leaves narrowly linear-lanceolate, 24 
long, 2™" wide, the lowest shorter: sepals ovate, acuminate, ee 
long: corolla distinctly bilabiate, violet (?) fading to lavender, 
2.5™ long, with a broad tube twice the length of the sepals, then
