NEW SPECIES OF CERASTIUM. 303 
Common on stony hills about San Francisco and else- 
where in middle California near the sea, being the C. arvense 
of my Bay-Region Manual, etc., but a most distinct species. 
C. Sonnet. Of twice the height of the last, and more 
slender, the cyme ampler, often 5-flowered: leaves oblong- 
lanceolate, # inch long, glandular-puberulent, along margin 
and on the midvein beneath glandular-hirtellous; those of 
the sterile shoots narrower, otherwise similar: bracts of the 
cyme broad, almost ovate, acute: pubescence of stem very 
short, spreading, glandular: sepals 2 lines long, elliptic- 
oblong, acute, lightly 1-nerved, with or without traces of 
lateral nerves, glandular-puberulent, more so marginally 
than superficially: petals deeply obcordate, twice as long as 
the sepals. 
Subalpine in*the Californian Sierras, my specimens from 
an altitude of 8,000 feet on Mt. Rose, 22 July, 1888, C. F. 
Sonne. 
C. apsuRGENs. Apparently biennial, with many decum- 
bent or assurgent branches forming a tuft on the crown of 
the slender root, these a foot long more or less, simple up to 
the long and narrow cyme, herbage altogether light-green, 
scarcely glandular or viscid, minutely rough-pubescent 
(under a lens appearing hispidulous): leaves 3 to 1} inches 
long, oblong-linear, obtuse: calyx scarcely 2 lines long, the 
sepals oblong, acute, hirtellous with scattered bristly hairs, 
not viscid, marked at base with a prominent but short rudi- 
ment of a midvein: petals not quite equalling the sepals, 
their segments very acute: capsule of nearly thrice the 
length of the calyx, gradually curved. 
Collected by the writer on wooded slopes of the San Fran- 
cisco Mountains, northern Arizona, 10 July, 1889.
