of streamlets in Yosemite Valley, 4,000 feet high, Bolander , 
Cal. St. Surv. 6033, Hb. n. 99; mountains near Carson City, 
Nevada,. C. L . Anderson . — Allied to the last, but readily 
distinguished by its pale flower heads, which look more like 
those of some cyperaceous plant, its broad and obtuse sepals, 
small ovary, very long style, shorter stigmata, and very short 
obtuse capsule.—The specimens before me are from 10 to 17 
inches high, pale green, with the auriculate sheaths often rose' 
purple; leaves £-1 line wide, like the stem compressed, but 
not ancipitous, shorter than the stem; 1-3 heads, 6-7 lines 
in. diameter; flowers 2£ lines long, pale or whitish-green, 
shining; sepals very obtuse, often mucronate or cuspidate, 
with broad membranaceous margins; stamens scarcely short- 
errand sometinfes even a little longer, than sepals; anthers 
twice to four times as long as filament, much exceeding the 
ovary; style often twice as long as the ovary; capsule, in the 
only fruiting specimen which I could examine, much shorter 
than the sepals; seeds (immature) very similar to those of 
the last species, 0.32 line long and more than half as wide, 
7-8 ribs visible on the side, reticulation distinct, but, as yet 
at least, no transverse lineolation visible. 
During the two years which have passed since the first 
part of this paper, pp. 424-458, was published, the attention 
of many botanical friends has been directed to our Junci , and 
their exertions have enabled me to add several new species 
to the foregoing list, complete the history of others, and make 
several additions and corrections. In the foregoing pages I 
have already acknowledged the liberality of Professors Roe- 
per and Decaisne, who have enabled me to study the Junci 
of Lamarck and of Michaux; I have now also seen fragments 
of those collected by Haenke on our western coast from the 
Herbarium of Prague sent by Professors Kosteletzky and 
Von Leonhardi, and those obtained on the north-west coast 
by the Russian explorers, communicated by Director Regel 
of St. Petersburg. Thus, I believe, I have had an opportu¬ 
nity of examining all the original specimens of the older au¬ 
thors; the single J.Pylcei, LaHarpe, from the “little island 
of Saint-Pierre-de-Miquelon, near Newfoundland,” remains 
unknown to me. 
The request for assistance in forming an Herbarium Jun- 
corum Boreali-Americanorum JSTormale (p. 424) has been 
generously responded to by twenty-three botanists, who have 
sent sets of 99 plants, to be distributed by me among the 
great standard herbaria of this country and" of Europe and 
among the contributing botanists themselves. They are quo¬ 
ted in these pages as Herb . norm . or Hb . n . The largest
