25. B, nitidus; glabriusculus, foliis radicalibus longissime petiolatis ternatls, foliolis 

 petiolatis profunde trifidis tripartitisve, segmentis latolanceolatis trifidis incisis, caulinis 

 supremis sublinearibus integris trifidisve, calyce patente denium reflexo subhirsuto, capi- 

 tulo subrotundo, carpellis orbicularibus compressis marginatis breviter mucronatis, —

Hab. Abundant on the lower fertile plains of the Columbia, where it attains the height of from 1 J to 2 J 

 feet, extending to the mountain vallies, where it is of humbler growth. Ifouglas. Canada, Mrs. PercivaL — 

 Allied to R. hispidus and R. Pennsylvanicus : but almost quite glabrous in all its parts, and the leaves are of 

 a remarkably thin and membranaceous texture. 1 have compared it with the R. nitidus of Mr. Elliott, whose 

 specimens are from Georgia, and I find it to be in every particular the same. Mr. C. S. Parker finds it on 

 the Ohio ; so that, in all probability, it is a general plant in North America,

Hab. Labrador. Herb. Banks. Mouth of the Columbia, Douglas^ Scouler; near the source of that 

 river, and on the eastern decUvity of the Rocky Mountains, lat. 52° to 55°, in woods and shady places. 

 Drummond. /S. Unalaschka. Nelson, y. Mountain woods, north of the Smoking River. Drummond, 

 Canada. Todd. — Flowers, generally, as figured by De Lessert, with abortive petals. Mr. Douglas's speci- 

 mens from the North-West coast have the petals thrice as long as the calyx. The style varies in length, 

 but is always recurved. The carpels compressed, margined, minutely dotted. The leaves, stems, and petioles 

 very variable in hairiness. Peduncles, too, sometimes very short, so that the flowers are hid among the 

 foliage; at other times much elongated. 



27. M. fascicularis ; appresso-pilosus, caule subramoso brevi, foliis longe petiolatis ter- 

 natis quiuato-pinnatisve, segmentis oblongo-obovatis cuneatisve pinnatifido-lobatis, calyce 

 patente villoso petalis duplo breviore, capitulis rotundatis, carpellis subrotundis compressis, 

 stylo subaeque longo recurvato. (Tab. VIII. B.) — Muhl in Bigel. Ft. Bast, ed, 2. p. 226.

Hab. Canada, to the south end of Lake Winipeg. Cleghom. Dr. Richardson. Drummond. — A very 

 distinct species, in habit most allied to R. bulbosns, especially in the leaves being much more compound 

 than is usual in this genus. Root densely fasciculated, throwing up from its crown many leaves and stems, 

 the latter scarcely exceeding the former in length, and both pubescent or pilose, with appressed hairs. In 

 some of Dr. Torrey's specimens from New York, the outermost leaves are simply 3-lobed; in Dr. Boott's 

 plants, from near Boston, the very outermost of the radical leaves are ternate, with obovate and somewhat 

 incised leaflets : but in most instances these leaflets are again deeply divided, the middle always much 

 petiolate, and itself often temately divided, so that the whole leaf is pinnated, with four lateral and one ter- 

 minal (always petiolated) leaflets, and these variously cut, and divided; those of the stem are generally 

 situated on long petioles. The petals are as variable as the leaves, obovate, oval, and oblongo-elllptical.
