pubescent and sometimes rather few and sparse. — Hook. Fl. i. 229 ; Turr. But. 

 Mex. Bound, t. 23, cusp of anther omitted. R. ferox, Smith. R. Californicum & 

 R. occidentale, Hook. & Arn. Bot. Beechey, 346; very small-leaved forms, glabrous, 

 but sometimes pubescent. A*, subvestitum, Hook. & Arn. 1. c. (not of Bot. Mag.)- 

 a form with densely glandular ovary, the glands in fruit developing mostly i'lito 

 very numerous and gland-tipped short prickles. R. Calif or nicuvi, Gray in Pacif. B. 

 Eep. iv. 88, combining the three last named. 



Hillsides, from San Diego to Humboldt counties, and also along the Sierra Nevada to Plumas 

 Co. Also Oregon, coll. E. Hall. A variable species, but well marked by its sagittate (ovate- 

 oblong or oblong-lanceolate) and mucronate-pointed anthers ; these about a line and a quarter in 

 length. 



-(- +- Anthers oval or didymoiis, very obtuse and 2Mintless. 

 ++ Flowers comparativeli/ large, dark pzirple-red. 



3. R. Lobbii, Gray. Minutely pubescent or glandular : stems with stout triple 

 thorns, but apparently destitute of scattered prickles or bristles : leaves small (less 

 than an inch), round-cordate, 3-5-cleft, and the roundish lobes obtuvdy toothed: 

 peduncles mostly 1-tiowered: flower pendulous, three fourths of an inch long, similar 

 to those of R. Menziesii, but the anthers oval and very obtuse, the back beset with 

 scattered warty glands : ovary densely clothed with sessile glands. — R. subvestitum, 

 Hook. Bot. Mag. t. 4931, but not Hook. & Arn. 



The living plant figured was "sent by Mr. Lohb to Messrs. Veitch and Son," from California, 

 probably from the northern part near the coast. It exactly accords with an indigenous specimen, 

 named at Kew, '' R. subvestitum, Hook. & Arn., Vancouver Island, Wood.'' It is not the plant 

 of Douglas on which R. subvestitum was founded. 



-f-f- Floiuers yelloiv or yelloivish, small : leaves very small, seldom half an inch in diam- 

 eter : anthers oval-oblong. 



4. R. leptanthum, Gray. Much branched and rigid, 1 to 4 feet higli, desti- 

 tute of scattered prickles, but with comparatively large single or triple thorns : leaves 

 roundish (often only a quarter of an inch wide and shorter than the thorns), 3-5- 

 cloft, and the lobes crenately incised or toothed : peduncles very short, 1-2- 

 flowered : calyx pubescent, commonly 4 lines long, cylindrical, and with the oblong 

 lobes more or less shorter than the slender tube : style undivided, glabrous : berry 

 glabrous. — PI. Fendl. 53. 



Var. brachyanthum, Gray. Calyx shorter, only 2 or 3 lines long, campan- 

 ulate or barely cylindraceous ; the lobes even longer than the tube, which is about 

 as broad as long : ovary densely glandular. — R. leptanthum, "Watson, Bot. King 

 Exp. 98, as to Calif, plant. 



Rocky Mountains of Colorado (where it was first collected by Br. James in Long's Expedition) 

 to New Mexico, Sierra Nevada on Mount Raymond at 8,000 to 9,000 feet, and above Sunnnit 

 (Bolandcr) to near Foit Tejon (Davidson) ; between the original form ami the variety whii-h 

 comes from foot-hills near Carson City, Anderson, Watson. This short-tlowered variety is remark- 

 able ; mature fruit of it unknown. 



-f- -{- Floivers greenish, white or dull purplish : leaves mostly an inch or two in diam- 

 eter : anthers shorter, mostly didymous : ovary and berry nnarmed and glabrous. 

 {Stems commonly xvithout, but vigorous shoots occasionally with scattered bristly 

 pricUes in all the species.) 



5. R. divaricatum, Dougl. Nearly glabrous or soft-pubescent : stems from 5 

 to 12 feet high, with Avidely spreading branches ; the thorns single or triple : leaves 

 roundish, 3-5-lubed; the lobes incisely toothed : 2-4-rtowered peduncle and pedi- 

 cels slender, drooping : flower one third of an inch long : calyx livi<l-purplish or 

 greenish-white ; its oblong or linear-oblong lobes about twice the length of the cam- 

 panulate tube and the cuneate-dilated or fan-shaped (white) petals : these only one 

 third the length of the tiliform lilaments and villous 2-cleft style : berry dark
