long, 6™™ wide, sessile, the upper surface somewhat dotted, lower 
surface arachnoid (under a lens): peduncles with pubescence like 
the stem but also somewhat viscid, bracts few, narrowly linear: 
involucral scales in about 5 ranks, the outer narrowly linear- atten- 
uate, the others lanceolate, acute, tipped with a green and glandular 
spot, below yellowish, chartaceous, keeled, the innermost some- 
times tinged with purple and considerably surpassing the others; 
heads with about 15 flowers, rayless: corolla straw color, about 
as long as the pappus, trumpet-shaped, gradually narrowed to the 
base, border with acute teeth, 1™™ long; style branches filiform, 
exserted, twining around each other at base; pappus thick, with 
an outer shorter row, barbellulate; akenes flat, villous, white. 
Collected on Mount Eddy at an elevation of 2225" by Dr. Edwin Bingham 
Copeland, August 17, 1903. 
This comes very near C. Breweri Gray, of which it may prove to be only 
a variety. It differs however, in the simple instead of much branched stems, 
more finely arachnoid pubescence, and leaves of different outline. The invol- 
ucral scales are the most distinctive; in C. Breweri they are attenuate and not 
keeled; in C. gracilis they are broader, acute, keeled, conspicuously green- 
tipped and glandular; the corollas are paler and the pappus not so rough. 
- Psilocarphus tenuis, n. sp.—Sparingly clothed with long loose 
white woolly hairs; stems filiform, erect or ascending, 3-5°™ high, 
with few slender divaricate branches: leaves oblong to elliptical, 
5-10™™ long, 3™™ wide, veiny and submembranous, mucronate 
at apex, the base of the opposite leaves connate-clasping: heads 
in the forks and at the ends of the branches, the involucral leaves 
4, ovate-oblong, folding over and almost concealing the flowers 
within, texture similar to the other leaves: fertile flowers few or 
many, completely enclosed by the obliquely-cuneate bracts, these 
gibbous, veiny, membranous, slightly woolly, 2.5™™ long, the apex 
orbicularly truncate or concave, the exserted membranous tips brown- 
ish, conspicuous, generally curved upwards: akenes shortly stipitate, 
narrowly obovate, 1™™ long: sterile flowers few, the corolla attenuate 
to the base, divisions reddish-brown. 
Type collected at Monterey, California, by Mrs. Joseph Clemens, July 1905. 
What seems to be the same, but too young for certainty, was collected by the 
author at Bakersfield, Kern County, California, April 4, 1893, and at Kaweah, 
Tulare County, California, April 27, 1895.
