(3069.) C. Lyallii, Wat, Proc. Am. Acad., XIV., 466.

C. cordifolia, Wat., Bot. King. Exp., 19, in part; Gray, Proc. Amer. Acad., VIII., 376; Torr. Bot. Wilkes, 299.

"Glabrous; stem erect from a running root-stock, simple or branched, a foot or two high; leaves few (4 to 8), petiolate, undivided, reniform to cordate, the margin sinuate, 1 to 3 inches broad; raceme pedunculate; flowers white; pods one inch long or less, on spreading pedicels, rather shortly alternate to a very short style, radicle cleft to the middle." On the southern borders of British Columbia. (Lyall.)

(125) C. Douglasii, (Torr.) Britton, Trans. New York, Acad. Sci., IX., 7. (1889.)

C. rotundifolia, var. purpurea, Macoun, Cat., I., 40.

I entirely agree with Dr. Britton in raising this plant to the rank of a species. It now takes the place of G. rotundifolia and its variety in Part I., 40 of this catalogue, references under G. rotundifolia going under G. rhomboidea, while those under G. rotundifolia var. purpurea, go here.

(129.) C. pratensis, Linn., var. occidentalis, Watson.

In springs in deep shade above the railway bridge at Nanaimo, Vancouver Island, June 3rd, 1887. (Macoun.)

Var. angustifolia, Hook.

Finlayson River, Lat. 61°, N.W.T., July 18th, 1887. (Dawson.) Cape Chudleigh, Ashe's Bay, Upper Savage Islands and Digge's Island,

Hudson Strait. (R. Bell.) The specimens collected by Dr. Bell were referred to C. pratensis in Part III., page 480. Since then, specimens received from Greenland, have shown that these are the variety with bright purple flowers.

(130.) C. hirsuta, Linn., var. montana.

This is a very distinct form and seems to be closely related to C. sylvatica, but differs from that species in growing on mountains and in wet places. It approaches C. oligosperma in having its leaflets almost petioled. The specimens hitherto referred to 0. hirsuta var. sylvatica, and collected in the Rocky and Selkirk mountains, belong here. Common on the wet slopes of Mount Queest and other high mountains in the Gold Range, near Griffin Lake, B.C., altitude 6000-7000 feet. (Macoun.) Another form near the coast at Burrard Inlet has also been referred to C. hirsuta, var. sylvatica, but it cannot be that species as it differs in many minor points besides growing in wet ditches.

(3070.) C. flexuosa, With.; Britton, Trans. N.Y. Acad., IX., 8. (1889.)

C hirsuta, Linn., var. sylvatica, Gray, Man., ed. V., 67 (1867); Macoun, Cat., I., 41.

Dr. Britton says of this species: - "So far as I have observed, its habitat is on rocky banks in more or less shaded woodlands; that of G. hirsuta being either actually in the water or in very moist situations. It appears to he a smaller plant than C. hirsuta, with a decidedly flexuous stem, the leaves smaller and with narrower divisions." Our knowledge of this species agrees exactly with that of Dr. Britton, and we have no hesitation in changing the names as above. Our specimens are from "dry rocks," close to Shannonville Station on the G.T.R, Hastings Co., Ont., 1864; and Island Portage, Dawson Route west of Lake Superior, 1872. (Macoun.)
