Notes: Carex quasivaginata C.B. Clarke was described from "Trondhjem" in the boreonemoral to middle boreal lowlands of central Norway. The holotype (K!) belongs to low-grown coastal subsp. vaginata, even if Clarke probably had the arctic-alpine race in mind. The names C. quasivaginata and C. vaginata subsp. quasivaginata are thereby not available for the arctic-alpine plant. Another option for a subspecific name is to base it on Wahlenberg's C. panicea var. sparsiflora, described from northern Fennoscandia. Syntypes for this name (UPS!) more resembles subsp. vaginata. The arctic-alpine race is therefore without an acceptable name as a subspecies. We suggest that a combination can be based on C. algida Turcz. ex V.I. Krecz. but type material for that name must be studied before a decision can be made.
The name C. sparsiflora was previously applied generally for the species, both in the Nordic area and in central Europe (following Steudel 1840). This means that geographical records and chromosome reports made under that name, even as late as the 1970's, refer to C. vaginata s. lat.
