Miss E. Vachell is responsible for the section of the flora included 

 in the following genus — Carex. She has worked at the local sedges 

 for five years, and made several interesting additions to the list of 

 species, as well as to the lists of habitats of the rarer forms. The 

 "critical" types have been submitted to Mr. A. Bennett, and the 

 sign ! ! in this genus will indicate that Miss Vachell or the Editor 

 has collected the plant in the locality to which it is attached, and 

 that the authenticity of the specimen is confirmed by Mr. Bennett. 

 The Editor's contributions will be denoted by Ed.
