and foliage of a small B. hispidus yet in no degree hispid, hirsute, or 

 even villous, but finely appressed-pubescent throughout, thinly so on the 

 older parts, but the half-developed later leaves appearing silky canescent: 

 lowest leaves a half-inch long, truncate at base, 3-cleft to the middle 

 and the segments crenately 3-lobed, the later ones twice or thrice as 

 large, deeply cut into 3 crenate and trifid segments: peduncles 1 or 2, 

 in flower little exceeding the leaves; sepals ovate-lanceolate, acute, 

 strigose-hairy corolla nearly one inch broad, the 5 petals narrowly ob- 

 cordate: fruit not seen. 



Ontario: At the Whirlpool Rapids, Niagara, 21 May, 1901, John 

 Macoun (no. 33581). As to habit, this plant lies between B. hispidus 

 and B. fascicularis; being like the latter in size, and like the former as 

 to its few and slender roots. Its pubescence is not that of either of 

 those; while the remarkably narrow sepals, along with broad distinctly 

 obcordate petals must compel its recognition as a good species. 



259. Ranunculus octopetalus Greene, 1. c. p. 33. 



Perennial, of the size and the upright habit of B. acris, but lower 

 part of stem and the long stout petioles densely and coarsely hirsute: 

 leaves ample, pinnately ternate, the subsessile lateral leaflets cleft into 2, 

 the long-stalked terminal one into 3 slightly cuneiform or sometimes 

 almost quadrate segments, these incisely toothed above the middle; the 

 rather loose panicle glabrous; flowers small, the expanded corolla about 

 */ 2 inch broad; petals commonly 8, sometimes 7 or 6, almost linear- 

 oblong, obtuse: achenes small for the group, moderately compressed, 

 sharply margined, tipped with a slender almost straight but distinctly 

 inflexed style, not numerous, forming a small globose head. 



Tennessee: In marshes of Knox Co., 10 June, 1893, T. H. Kearney; 

 the specimens labelled B. hispidus, but surely very erroneously. 



260. Ranunculus rudis Greene, 1. c, p. 33. 



Perennial, the several very thick stems (often 7 2 inch in diameter) 

 hollow, therefore weak and reclining, often 2 feet long, rather coarsely 

 and loosely hirsute: leaves ternate. the radical on long petioles, the 3 

 primary leaflets on nearly equal stout petioles of an inch or less, each 

 deeply cleft or parted into 3 broadly cuneate incisely lobed or toothed 

 segments, glabrous above, villous-hirsute beneath along the veins; cau- 

 line leaves similar but short-petioled, the uppermost simple and sessile, 

 incised like the segments of the lower: flowers small, numerous and 

 somewhat panicled near the ends of the branches; sepals oblong-lanceo- 

 late, obtuse, hairy, persistent even under the head of full grown fruit: 

 petals small, not even equalling the sepals, round-obovate : achenes little 

 compressed, turgid, smooth, the ensiform beak about as long as the 

 body, the whole forming a large subglobose or almost ovate head. 



Northern California: Discovered in a wet meadow in „Devil's 

 Garden" (Plumas or Lassen County) June, 1895, by Mrs. R. M. Austin.
