 leaves small, thin, an inch broail, tlie lowest subentire or usually more or less deejilv 3-])artcd 

 or divided ; segments or leaflets ovate, obtusely few-toothed : flowers but hidf inch in diam- 

 eter: achenes broadly and sharjjly margined, few in number, tipped with a strong flat

R. fascicularis, Muiil. A span or two high, tufted, soon spreading, but no sarmentose 

 stems: fascicled roots tuberou.s-thickened or fusiform: i)ubescence almost all cIo.>selv ai>- 

 pressed: earliest radical leaves ovate or oblong and- almo.st entire or rounded and 3-lob.-.l or 

 parted; later and principal ones of oblong outline, and di.spo.sed to be pinnatelv quinate, 

 some with divisions or leaflets again 3-7-partcd ; lobes from linear-spatulate to oblongi 

 obtuse : petals obovate-oblong, from quarter to lialf indi long : akencs lenticular, le.ss mar-

O O IVtals 7 to 16; no creeping nor procumbent basal stems: plants of Mexican tvpe. 



R, macranthus, Scheele. Hirsute: stems erect and a foot or two high, or 2 to 3 feet 

 long and declining, commonly robust : leaves nearly as of R. srpinitriomilis, but many qui- 

 nate : petals from a third to nearly full inch long, from obovate to oblong : akenes nnistlv 

 numerous in a large head, ovate or orbicular, conspicuously thin-margined, at length with a 

 rather short broadly flat-subulate beak, the slender upper ])ortion of the long straight stvle 

 falling away. — Linn asa, xxi. 585; Torr. Bot. Mex. Bound. 29; Rothrock in Wheeler, Hep.

R. orthorh:^nchus, Hook. From sparsely hirsute (with spreading hairs) to nearly gla- 

 brous : stems erect, a foot or so high from a fascicled root of thick fibres : leaves mostly of 

 oblong general outline and pinnate division into 5 to 7 leaflets or segments (lower commonly 

 short potiolulate, upper confluent), the.se again usually cleft or incised : petals a third to half 

 inch long, ol)Ovate (sometimes purjdo underneath), much surpassing the reflexed »<Mm 

 fleciduous calyx: akenes usually not numerous in the head, ovate, nearly two lines long, 

 strongly margined, bearing a slender subulate rigid and straight beak of nearly e4]ual 

 length which consists of the wholly per.^istent style. — Gray, Proc. Am. Aciul. xxi. 377. 

 Varies cxtemely in foliage: the typical form, stenophvi.ms, with :ill the leaves somewhat 

 bipinnately dissected into segments of a line or less in width (as in the figure), or some 

 radical ones simply divided into broad cuneate or ohov.ate 2-3-lol)ed or totithe<l segment.s or
