PLATYSTEMON AND ITS ALLIES. 189 
almost hyaline, not broader at summit than the anther, but 
often with a pair of short erect subulate teeth standing almost 
parallel to the base of the anther: fruit erect, oblong, # inch 
long including the styles and slender-subulate stigmas; car- 
pels 18 or 20, glabrous or with here and there a bristly hair, 
moderately constricted, 7 to 9-jointed, the joints not nerved 
or lineolate, but obscurely somewhat tuberculately uneven. 
A beautiful species, manifestly allied to P. verecundus by 
habit and lance-linear foliage, and its fruits are rather simi- 
lar, though not nodding; but the stamens are very peculiar 
and characteristic. Nor do I know any other species with 
white corollas. The only specimen, a fine one, is in my own 
herbarium, forming part of a purchase made from Mr. 8. B. 
Parish ten years since. It is from the foothills of the San 
Bernardino Mountains. 
43. P. microtosus. Slender, sparingly pilose, 10 inches 
high, the peduncles rather longer than the leafy branches: 
leaves linear, pale, thin, 3-nerved, 2 or 3 inches long, usu- 
ally abruptly acutish and indistinctly or else not at all cal- 
lous-tipped: corolla an inch broad, saucer-shaped, cream- 
color tinged with red, deciduous: stamens not very unequal, 
none of the filaments broader than linear-spatulate : fruit 
short-cylindric, less than } inch long including the short 
linear stigmas; carpels 12 to 16, small and short-jointed, 
glaucous and almost white in maturity, thin-walled, the 7 to 
9 joints with a delicate line on the back, the sides with a few 
thin wrinkles or none. 
Arroyo Grande, San Luis Obispo Co., March, 1895, col- 
lected by my former pupil Miss Alice King ; also apparently 
the same from Ojai, Ventura Co., 18 March, 1895, in Herb. 
Calif. Acad., by F. W. Hubby; yet this last has narrower 
and somewhat spatulate-linear foliage, the like of which I 
have not otherwise observed in the genus. It may eventually 
be proven distinct.
