Holm, Theo., S tu dies in the Cyperaceae. XXI New or 



little known speeies of Carex. (American Journal of 



Science. XVII. p. 301—317. iig. 1 — 13. April 1904.. 



The following are described as new : Vigneae: Neuroc/ilaenae: C. neuro- 

 chlaena (Yukon), Acanthophorae : C. vagans (Oregon), C. phaeolepis 

 (Oregon), C. chrysoleaca (C a 1 i f o r n i a\ C. vitrea (California). Can'ces 

 genuin ae : Melananthae : C. venustula ( A 1 a s k a and British Columbia), 

 C. microchaeta (Yukon"), Microrhynchae : C. vulgaris Fr. var. limno- 

 phila (St. Paul Island, Columbia Glacier) var. hydrophila 

 (Yukon), var. lipocarpa (Alaska, Vancouver Island, British 

 Columbia), C. sphacelata (Yukon), C. chionophila (Yukon), C. con- 

 similis (Yukon), C. cyclocarpa (Yukon), C. limnocharis (Yukon), 

 C. millegrana (S. Dakota), C. dives (Oregon, British Columbia), 

 Aeorastachyae: C. macrochaeta Mey. var. emarginata (Alaska) var. 

 macrochlaena (St. Paul Island). C. nesophila (St. Paul Island), 

 C. lacunarum (C a 1 i f o r n i a), Physocarpae : C. physochlaena (Y u k o n). 

 The paper contains, also, a discussion of several critical speeies for in- 

 stance of C. cryptocarpa Mey, which is not to be confounded with C. 

 Lyngbyei Hörnern, and probably not with C. filipendula Drej. either. The 

 so-called C. deeidua Boatt of North America has proved very difie- 

 rent from this speeies, and has been refered to C. vulgaris Fr. as the 

 variety lipocarpa. C. magnifica Dew. is the plant generally named as 

 C. Sitchensis Presc, while real C. Sitchensis has been described as C. 

 Hornellii by Professor Bailey. Theo. Holm. 



HOLM, THEO., Studies in the Cvperaceae. XXII. The Cype- 

 raceae of the Chilliwack Valley, British Columbia 

 (between lat. 4Q n and lat. 49 ü 10'; and long. 12P25' 

 and long. 12 2°). (American Journal of Science. XVIII. 

 p. 12 — 22." fig. 1—9. a— d. July 1904.) 



Scirpus Macounii is described as new; furthermore two varieties of 

 Carex scirpoidea Michx. stenochlaena and gigas. 



Among the speeies enumerated the following oeeur, also, in the 

 aretie region viz. : Carex nardina, festiva, scirpoidea, Eriophorum gracile 

 and Scirpus caespitosus, while Carex canescens and Eriophorum angusti- 

 folinm are even circumpolar, most of the others are confined to this 

 continent. In regard to the Carices it seems stränge that there are so 

 many Vigneae in proportion to Carices genuinae when we remember 

 that the latter usually predominate in this part of the continent. Scirpus 

 Macounii is an ally of 5". sylvaticus. Theo. Holm.
