Carex magnifica is distributed from Alaska, following 

 the coast, south to California. 



Carex ScJiottii Dew. 



Dewey's original diagnosis has been cited in our paper 

 dealing with the structure and affinities of some of 

 Dewey's Carices^^ and the species was accepted by C. B. 

 Clarke as identical with C. ohnupta Bailey, but distinct 

 from C. BarbarcB Dew. Nevertheless Kiikenthal (1. c. p. 

 305) refers the species, as a mere synonym, to C, 

 Barbarce. Mr. S. B. Parish.^^ however, holds the opinion 

 that they are distinct. 



Carex ScJiottii resembles C. magnifica in many re- 

 spects, but the spikes are longer and more slender, 

 drooping on long peduncles and remote. 



Carex lacunarum nob.^^ 



As may be seen from the diagnosis (1. c.) and the 

 figures (1. c. p. 303) the species is very distinct from the 

 others of this section, especially on account of the lighter 

 color and structure of the perigynium and squama; as a 

 matter of fact the squamae of the basal pistillate flowers 

 are very prominently aristate; moreover the perigynia 

 are appressed, not spreading. 



In these sections : Crinitce, Apertce and Magnificce the 

 distribution of the sexes thus shows a variation well 

 marked. In C. crinita the terminal spike is some- 

 times gynsecandrous, or it consists of a pistillate portion 

 above and below the staminate ; or there may be a single 

 pistillate flower subtended by a bract below the terminal, 

 staminate spike ; the pistillate are often androgynous. 

 In C. maritima the terminal spike may be androgynous, 

 and in some cases two pistillate spikes may be developed 

 in the axil of the same bract. In C. aperta there may be 

 from one to three pistillate flowers at the base of the 

 terminal, staminate spike. Androgynous staminate 

 spikes ©ccur in C. magnifica ] the pistillate are mostly 

 androgynous ; furthermore the terminal may also be
