Louis Acad. 2. 438. J acutus, var. spherocarpus, Engelm. in 
Wheeler’s Rep. 6. 376. Southern California, frequent in marshes in 
the Coast Ranges from San Francisco to San Diego. J. acutus of the 
Old World has a shorter and more spreading panicle, shorter spathes 
and bracts,a more triangular and more acute capsule, and usually 
more distinctly caudate seeds: the sheaths at the base are also more 
abruptly contracted. The tough scapes of the present species are split 
by the Indians and used in binding together the material of their baskets. 
Juncus (ArticuLAT1) NEVADENSIS. Scape very slender from a 
slender horizontal rootstock, somewhat compressed, } to 2 feet high: 
leaves very narrow (rarely a line wide), subterete; ligules present : 
spathe short and very narrow: heads small, few to rather many in a 
short open panicle, frequently solitary: perianth-segments brownish, 
lanceolate, acuminate, 2 lines long: stamens 6; anthers longer than 
the filaments: stigmas long-exserted: capsule oblong, abruptly con- 
tracted into the stout style, which nearly equals the perianth: seeds 
minute, oblong, apiculate at each end. — J. pheocephalus, var. gracilis, 
Engelm. Proc. St. Louis Acad. 2. 473. Frequent in the Sierra 
Nevada, from Kern County (Rothrock) to Oregon. Resembling 
J. articulatus in habit, but much more slender; distinguished from 
J. pheocephulus by its slender habit, subterete scape and leaves, 
ligules, smaller heads, more abruptly acute capsule, and much smaller 
and narrower seeds. 
PuHyLLospapIxX Torreyi. Stem and leaves much elongated, 
scarcely a line wide, the latter flat, faintly 1-nerved, with sheaths 
2 to 10 inches long: spathes 2 to 6, near the summit of an elongated 
peduncle, the dilated portion 14 or 2 inches long, foliaceous above: 
spadix enclosed, 14 lines wide, with 15 to 20 ovate-oblong acute 
appendages within the margin and above the attachment of the corre- 
sponding ovaries, 2} to 3 lines long: ovaries cordate-sagittate, some- 
what flattened dorsally and carinate, 2} lines long; stigmas half as 
long: fruit unknown. — Collected by Dr. Torrey at Santa Barbara, 
in flower. It is apparently the same that is described and figured by 
Ruprecht under the name of P. Scoulerd (Mém. Acad. Petersb. 7. 58, 
t. 1 and 2, f. 5-16), from the mouth of Russian River, though repre- 
sented with short peduncles, a single spathe and broader leaves. 
P. Scouleri, Hook. Fl. Bor.-Am. 2. 171, t. 186, may be distinguished 
by its ovate-oblong ovaries, rounded at base; its mature fruit is also 
unknown.
