Art. II. — Studies in the Cyperacew ; by Theo. Holm. 

 XXII. The Cyperacese of the Chilliwack Valley, British 

 Columbia (between lat. 49° and lat. 49° 10'; and long. 121° 

 25' and long. 1 22°). (With figures in the text drawn from 

 nature by the author.) 



Through the courtesy of Mr. James M. Macoun, the writer 

 has had an opportunity of examining a collection of Cyperacece 

 which was made by him in the Chilliwack Valley during the 

 summer of 1901, and upon which we take pleasure in present- 

 ing the following report. With the exception of Seirpus 

 Maeounii most of the others are old and well known species, 

 but nevertheless of some interest from a geographical point of 

 view, besides that, several of these represent types that have not 

 hitherto been clearly accounted for, viz : Car ex seirpoidea, C. 

 vulgaris var. lipoearpa, C. speetabilis, etc.
