(3086.) C. parviflora, Dougl.; Hook. Fl. I., 225.
Distinguished from C. perfoliata by its spatulate to filiform-linear radical leaves, and its flowers scattered in a loose raceme on slender pedicels. Abundant at Goldstream, Vancouver Island, amongst gravel, May 18th, 1887. (Macoun.)
On river banks, probably sand-washes, British Columbia to Oregon. (Gray.) Vicinity of Victoria, Vancouver Island, 1885. (Fletcher.') Abundant on gravel banks at Cedar Hill, Coldstream, Cowichan River, Nanaimo and Qualicum, Vancouver Island, 1887. (Macoun.)
(3087.) C. arctica, M. F. Adams.
Extends from the Alaskan shores and islands to adjacent Asia. (Dr, Gray, in Proced. Amer. Acad. Sci., XIV., 279.)
(3088.) C. tuberosa, Pall.
Mainly Asiatic, but has been found at Plover Bay by Rothrock; and Mair collected it somewhere in Arctic Alaska. (Dr. Gray l.c.)
(3089.) C. asarlfolia, Bongard, Veg., Sitch, 137.
Dr. Cray says this species ranges from the Rocky Mountains in Montana and Idaho to Sitka. Cold water River, B.C., June 14th, 1877. (Dawson.) Cedar Hill, Goldstream, and Nanaimo, Vancouver Island, 1887. (Macoun.)
(334.) C. spathutata, Dough; Hook. Fl. I., 226.
C. perfoliate,, var. spathutata, Torr.; Macoun, Cat., I., 83. C. gypsophiloides, Fisch. & Meyer.
Small, but comparatively large-flowered, an inch to a span high; cauline leaves from lanceolate-ovate to narrowly lanceolate, rarely connate into a round peltate or cupulate disk. Vicinity of Victoria, Vancouver Island, 1876. (Dawson.) Cedar Hill, and Mount Tolmic, Victoria, Vancouver Island, 1887. (Macoun.)
Var. tenuifolia, Cray, Proced. Amer. Acad., XIV., 282.
C. exigua, Torr. & Gray; Macoun, Cat., I., 83.
This has the cauline leaves narrowly linear, and is easily separated from the species by this character alone. Cedar Hill, and Mount Tolmie, near Victoria, Vancouver Island, 1875. (Macoun.)
(337.) C. sarmentosa, Bongard, Veg. Sitch., 137.
Dr. Gray says of this species: - "+It would seem to be a species intermediate in certain respects between C. parvifolia and G. Chamissonis with the alternate leaves of the former, and these broadly ovate, obo-vate or the radical rotund, the larger of the latter with a blade half an inch long." Specimens collected in the valley of Eagle River at Griffin Lake in the Gold Range, were exactly the same as those found on the coast 35Q miles to the west, and identical with all our other specimens of C. parvifolia; but those gathered in the bed of the same stream, at an altitude of 6500 feet, were altogether different and undoubted C. sar-mentosa, as the species is defined by Dr. Gray. In addition to his characters, I may remark that all the stems are more or less curved and produce bulblots in the axils.
