i. 19, The specific name is generally appropriate, but on the Pacific 

 coast there is a smoothish or smooth form, viz. : — 



Var. Oreganus. Lucidulous, and with only scattered hairs, or 

 sometimes hardly any. — R. nitidus, in part, Hook. Fl. i. 20. — Shady 

 and wet grounds, Oregon, on the Columbia, to Fraser River. I use 

 the name which Messrs. Howell and Henderson have proposed for 

 this as a species. 



GOOD Ascending, also creeping by procumbent rooting branches or 

 stolons : short-subulate styles stigmatose for the whole length, and 

 all or nearly all persistent in the beak : principal leaves of ovate 

 or roundish outline, not rarely white-variegated or spotted above, 

 some only 3-parted, some divided, and with the middle lobe petiol- 

 ulate ; lateral ones either petiolulate or sessile. 



R. REPENS, L., and partly so of American authors. — Low grounds, 

 Nova Scotia and Canada to Virginia, New Mexico, &c., generally only 

 in waste grounds near the coast, where it is naturalized from Europe, 

 but also indigenous in some places. Here belongs H. Clintonii, Beck, 

 Bot. 9, doubtless an introduced plant. 



3. Long-styled and mostly long-beaked, i. e. styles more or less elon- 

 gated and attenuate iipwai-d, stigmatose only at or near the tip, 

 sometimes all persistent, more commonly with the slender upper 

 part deciduous or at lengili breaking away from the basal, which 

 remains as a beak : perennials. 

 o Petals 5 : primary radical leaves or some of them (at least in dry 

 soil) commonly undivided and only 3-parted, but succeeding ones 

 3-o-foliolate. 



R. SEPTENTRiONALis, Poir. This I take to include the greater 

 pait of the assemblage of forms which have passed for R. repens in 

 this country. It includes R. septentrionalis, Marilandicus, tomentosus 

 (hairy form), lucidus (glabrous form), and repens, var. of Poir, Diet. vi. 

 112-127: also R. hispidm, Michx., as to the Southern plant upon 

 which was founded R. Carolinianus, DC. ; R. nitidus, Muhl., not 

 Walt. ; R. Be/visit, DC. ; R. pnlmatus, Ell. ; R. fascicidaris, Schlecht. 

 Animad. Ranunc. ii. 30, t. 2, (not truly of Muhl.,) therefore the 

 R. Schlechtendalii, Hook, as to type ; and R. intei^medius, Eaton. 

 R. Philonotis and R. lanuginosus of Pursh are probably of this spe- 

 cies, mistakenly named. The species ranges from New Brunswick 

 to Manitoba and south to Texas. In wet ground some summer stems 

 are procumbent or sarmentose, and these occasionally strike root at 

 the nodes.
