et (ut basis culmorum) rudimentis foliorum purpureis striatis 
tectum, radicibus capillaceis copiosissimis implexis. Culmi 
3-11-pollicares, graciles, triquetri, scabriusculi, basi foliati. 
Folia plana vel involuta, graminea, ^-f lin. lata, culmo bre- 
viora, apice setaceo-attenuata, scabra. Spica 3-9 lin. longa, 
2-3 lin. lata, basi flosculis femineis 4-12 instructa, apice ssepe 
plus quam dimidiatim mascula. Squama; ssepe demum deco¬ 
lores ; femineae deciduse, inferiores 1-2 cuspidatse; masculae 
angustiores, omnes margine albo-hyalinse. Perigynium 1 i- 
2-," 0 lin. latum, demum corneum. Achenium Ao _ l-ro bn.

neum, basi styli apiculatum. Racheola subulata, lsevis, acuta 
vel biloba, achenium ssepe superans, antice adest. Stylus basi 
bulbosus. Stigmata 3. 
Drejer justly notices the resemblance of this species to G. supina. 
He associates it with G. rupestris, but the almost horny texture 
of the perigynium is unlike that plant.

rigyniis pallidis squama mutica longioribus, pube paulo lon- 
giore. 
The specimen figured is from Germany.
