T. Holm — Studies in the Gyperacece. 267 



G. cryptantha Holm nov. sp. (fig. E). 



Roots very slender ; rhizome short, cespitose ; culms numer- 

 ous until 45 cm in length, triangular, scabrous above ; leaves 

 shorter than the culm, about 25 cm in length, narrow, flat, 

 scabrous along the margins and on the lower surface, their 

 sheaths short, pale brown, thin in texture, not fibrillose ; inflo- 

 rescence very short, from 1J to 2 cm in length, consisting of 2 

 or 3 contiguous, sessile, reddish-brown spikes, mostly andro- 

 gynous with a few female flowers at base ; bracts scale-like, 

 obovate, brown, membranaceous, the midrib sometimes excur- 

 rent as a bristle-like awn ; scales of staminate and pistillate 

 flowers (fig. F) broadly elliptic, acute, shining reddish brown, 

 pointed, the margins hyaline ; utriculus (fig. Gr) rather broadly 

 elliptic, attenuated at both ends, pale brown, glabrous, coria- 

 ceous, with several, distinct nerves, the beak short, entire ; 

 caryopsis dull and brown, roundish in outline, almost tiat ; 

 stigmas 2. 



In dense mats along small streams between Kussiloff and 

 Kenai. Its nearest ally is G. heleonastes Ehrh., from which it 

 differs in its narrow inflorescence and shining reddish brown 

 scales, which are larger and much broader, almost entirely con- 

 cealing the utricle. 



G. Iceviculmis Meinsh. 



This species has been known for many years, but has not 

 been well understood ; it was referred to C. elongata by 

 BoDgard ; to G remota by Treviranus, and as " potius G. 

 glareosa" by Ruprecht, while L. H. Bailey described it as a 

 variety spai^siflora of G. Dewey ana Schw. It was not until 

 1893 that Meinshausen segregated it as a species, and his 

 diagnosis reads as follows: " Radix csespitosa, fibrosa; culmis 

 tenuissimis acute triquetris, 1—1^ ped., flaccidis lsevissimis 

 inferne foliatis ; foliis linearibus plains, infimis brevissimis, 

 summis dimidio culmi subsequantibus ; spica elongata, spiculis 

 4-8 subglobosis remotius interrupts, infima ssepe valde remota, 

 ferrugineo — viridibus, basi masculis ; bracteis squamseformibus, 

 ima setacea longe aristata rarius foliacea spiculae 2-3 — plo. 

 excedente ; perigyniis ovatis rostro acuminato, ore minimo 

 integro, piano convexis marginibus acutis scabris, utrinque 

 rubro nervatis patulis, apice paulo incurvatis demum fer- 

 rugineis, squama ovata acuta v. acuminata ferruginea acute 

 carinata paulo breviora." 



The specimens examined by Meinshausen were from Sitka 

 and Kamtschatka (legit Mertens). Dr. Evans collected it on 

 edges of bogs on cleared lands, Wrangell ; along the beach 

 above high tide, Howkan ; in woods, common, Kussiloff.
