(2505.) C. capitata, Linn.; Macoun, Cat. IV., 109.

Damp, grassy places, Methy River, Lat. 57°, N.W.T. 1888. (J. M. Macoun.)

(2507.) C. dioica, Linn.

Professor Bailey informs me that the specimens placed under this species in Part IV., 109, belong to G. gynocrates. This species is therefore cancelled, and references under it go to G. gynocrates.

(2524.) C. Jamesil, Schweinitz; Bailey, Mem.Torr. Bot. Club., I, 48. References under G. Steudelii, Kunth, Part IV., 113, belong here.

(2528.) C. Sartwellii, Dew. Sill. Journ. XLIII, 90. (1842.)

References under G. disticha. Huds, Part IV., 114, belong here.

Prof. Bailey in Mem. Torr. Bot. Club, I., 8, says that "the American plant is abundantly distinct from the European G. disticha, Huds." Prof. Dewey and Dr. Boott thought otherwise, but we fully agree with Prof. Bailey in keeping them apart.

The perigynia arc considerably like those of the C. canescens group. This species stands midway between C. festiva and C. heleonastes."

Professor Bailey writes me that this species is of Very doubtful occurrence in Canada, so we cancel it.

(3193.) C. Eleocharis, Bailey. Mem. Torr. Bot. Club, I., 6.

"One of the Vignea, perhaps allied to C. tenella, Schk.; very slender but stiff, half a loot high, both leaves and culm filiform and smooth; spikes two or three, each bearing from one to three flowers, closely aggregated into a very small and apparently monostachyous head, evidently staminate above; perigynium short-ovate, turgid, flat on the inner face, marginless and nerveless, dull brown, beak entire or nearly so, as long as or longer than the thin hyaline scale." Collected on the Saskatchewan Plains, near Fort Carleton, in August, 1872. Col. Olney named it C. glareosa, and under this name it was distributed. It has never been seen since, but often looked for.
