p. 286; Roseny., Nye Bidrag p. 70; Meinshausen, Cyperac. Fl. Russl. p.257;

Culms densely tufted, striate; no stolons; upper sheath with 
short leaf, lower ones leaf-less; one terminal spike; lowest scale 
sterile, as long as or longer than the ovate spike, mucronate with 
a long rigid green point; achene smooth; stigmas 2. 
The specimens from Greenland agree not well with any of the two 
species (austriacum and germanicum) in which Palla (Ber. d. Deutsch. 
bot. Gesellsch., 1897, p. 468) has divided Scirpus caespitosus (Tricho- 
phorum caespitosum (L.) Hartm.), and we prefer to retain the old 
collective species.

70° (), East Greenl. 60°—63° (). Eur.: Samoyede Land.
