narrow herbaceous margin minutely and mostly bluntly toothed. — 

 Near Fish Ponds, Mohave Desert; S. B. & W. F. Parish, May, 

 1882. Resembling A. elegans, but the fruiting bracts much less 

 conspicuously toothed. 



Atriplex Paiiryi. Dioecious (?), perennial and woody, much 

 branched and with rigid spinosely tipped slender divaricate leafy 

 branchlets, white-scurfy throughout : leaves thick, sessile, cordate or 

 broadly ovate, acute, 2 to 4 lines long : pistillate flowers 1 to 4 in the 

 axils ; bracts sessile, united below into a compressed-campanulate sac, 

 becoming thick and rigid, bordered above by the broader rounded fi'ce 

 margins, the whole about 1| lines long in fruit and the margins some- 

 what more in breadth. — Near Colton, California ; Dr. C. C. Parry, 

 1881. Resembling A. confertiflora, but with much smaller fruiting 

 bracts, and their margins more broadly dilated in proportion. 



KociiiA Californica. Silky-pubescent and subtomentose through- 

 out, much branched and the branches divergent : leaves linear-oblong, 

 5 to 6 (on the branches 2 to 4) lines long, about a line broad : flowers 

 1 to 5 in the axils, the calyx developing a wing about 3 lines broad. 

 — Southern California; near Colton (C. C. Parry, 1881), and at 

 Rabbit Springs, San Bernardino County (S. B. & "W. F. Parish, 

 May, 1882). Readily distinguished from K. Americana by its more 

 diffusely branched habit and its proportionately broader leaves. 



Polygonum (Avicularia) intermedium, Nutt., in herb. Annual, 

 glabrous or somewhat rough-puberulent, much branched from the 

 base, the slender reddish quadrangular branches decumbent or pro- 

 cumbent, a foot long or less : leaves linear-lanceolate, acute, ^ to 1 

 inch long ; the acuminate triangular sheathing stipules entire or finally 

 lacerate : flowers axillary and in leafy-bracteate spikes, small (a line 

 long or less), rarely reflexed in fruit: stamens 8. — On bluffs of the 

 Columbia River, Oregon ; C. G. Pringle, October, 1881, and by 

 Nuttall, probably in the same region. Resembling P. coarctatiim, but 

 with much smaller flowers. 



Eriogonum (Ganysma) apiculatum. Annual, slender, some- 

 what branched from the base, a foot liigh, nearly glabrous, the branches 

 slightly glandular: leaves all radical, slightly hispid, spatulate, 1| 

 inches long : jjedicels slender, spreading, 2 or 3 lines long, or the alar 

 erect and longer: involucres turbinate-campanulate, nearly a line long: 

 flowers nearly glabrous, pinkish, a line long, the outer segments obcor- 

 date, the inner oblong-obovate and emarginate, all apiculate in the 

 sinus. — On the San Jacinto Mountains, at about 9,000 feet altitude ; 

 Parish Brothers, July, 1881. Of the E. tricJiopodum group.
