486 TRANS. OF THE ACAD. OP SCIENCE. 



of streamlets in Yosemite Valley, 4,000 feet high, JBolander, 

 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 \-\ 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- 

 er, and sometimes 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 Koe- 

 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, La Harpe, 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 Normale (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 lib. n. The largest
