 Animad. Hanunc. ii. 28, under R. recurvatus. R. occidentalls (exd. var. cohi/s) &, R. Nel- 

 sunii, Gray, Proc. Am. Acad. viii. 374. R. Schlechtendalii, Hook. Fl. Bor.-Am. i. 21, as to 

 plant there described, but not tlic plant of SclUecht. {R, fascicularis) to which he referred 

 it, and which was the type. A'. Eiseni, Kellogg, Proc. Calif. Acad. Sci. vii. 115, and R. occi- 

 dentalis, var. Eiseni, Gray, L c. (in its principal part), is only a short-styled form of this 

 species. — Open woods and low ground, northern Kocky Mountains to the Alaskan coast 

 and islands, and southward to the borders of California, first coll. by Nelsori, then by 

 Chamisao. Kuttall's original is low, rather slender and naked-stemmed, small-leaved, but 

 pretty large-flowered, the oblong or narrowly obovate petals 4 lines long : carpels glabrous 

 with often a few bristly hairs toward the back. 



Var. Rattani, Gray, l. c. Like the typical form; but akenes papillose-roughened as 

 well as densely liispidulous. — On the Klamath, N. California,' Rattan, with short and stout 

 strongly hooked beak ; Josephine Co., S. W. Oregon. Ilowelt, with more slender beak and 

 sparser hairs on the akene. 



Var.* roblistus, Gr^vy. a span to a foot or more high, with stout stems, ample leaves 

 (2 to 4 inches in diameter), and large flowers : petals broadly obovate, 4 to 6 lines long: 

 akenes even 2 lines in diameter and numerous in the head. — Proc. Am. Acad. xxi. 373.

 Gray, Proc. Am. Acad. viii. 374. — Alaskan Islands, especially Uualaska, Attar, Kyska^ 

 &c., Harrington, Dall, &c. 



R.* Turneri, Greene. Habit and foliage much as in the taller and stouter forms of the pre- 

 ceding, but flowers larger, 9 to 15 lines in breadth, long-peduncled : carpels more numer- 

 ous, 50 to 60 in a head and tipped with very strongly circinate-revolute styles. — Pittonia, ii. 

 296, & Erythea, iii. 54, excl. syn. R. recurvatus, var. robustus. — Northern Alaska, on the 

 Porcupine River, Turner. This species may perhaps belong to the next subdivision, but the 

 mature akenes necessary to decide this point are not at hand. 



2. Broad-hooJc-styled ; with recurved-hooked stj'les shorter than the ovary, broad and flat, 



stigmatic for much of their length, wholly persistent in a very strong and flat triangular 



or gladiate hooked beak, which is much shorter than the flat akene and confluent with its 



sharp margin : radical leaves divided or nearly so, petals only 5. 



R. acriformis, Gr.^^y. Strict and slender, a foot high, hirsute with short mostly appressed 



pubescence : leaves all palmately or pedately 3-5-parted or divided into narrow 2-3-cleft 



segments and lobes, the latter lanceolate or linear and mostly entire; petals orbicular- 



obovate, a quarter inch long, hardly double the length of the spreading calyx : akenes over 



a line long, with curved beak of half its length.—- Proc. Am. Acad. xxi. 374. R. acrix 



Hook. Fl. Bor.-Am. i. 18 (partly), & Lond. Journ. Bot. vi. 66. — Eastern part of Rocky 



Mountains in Brit. Am., lat. 58°, Drummond ; Wyoming, Parry (distrib. as A', ajffinis). Wind 



River, Forwood, and near Cheyenne,'- Greene, the latter coll. July, 1872. 



R. canus, Benth. Erect or ascending, robust, a foot or two high, soft villous with white 



hairs when young, at length commonly green and sparsely villous or glabrate : leaves mostly 



3-divided and the middle or all the leaflets petiolulate, all more or less cuneate and 2-3-cleft 



with the lobes incised : petals obovate, half inch or less in length, fully twice the length of 



the reflexed soft-villous calyx: akenes fully 2 i lines long, the broad and hooked beak less 



than a line long. — PI. Hartw. 294; Gray, 1. c. R. daliforninis, var. canns, Brew. & Wats. 



Bot. Calif, i. 8. 7^ occidentalis, var. canus, Graj', 1. c. viii. 374. — Low grounds, valley of 



the Sacramento, California, Hartweg (in flower), probably near Chico, where now coll. in 



flower and fruit by Mrs. Bidwell.^ 



1 Mendocino County, Calif., Blankinship, and reported from Mt. Hauiilton, Central Calif., by 

 Greene, Erythea, i. 88. 



2 And on the Laramie River, Crandall. 



3 The type of this species is .silky-lanate. throughout and appears to be an unusual form not .since 

 rediscovered. Prof. Greene (Erythea, ii. 189) believe.s the greener sub-glabrate form a distiuct 

 species, whicli he has called R. hesperoxgs. He adduces, however, no satisfactory difl"erences other 

 than the more deciduous indumentxun.
