This well known southern plant, reaching its northern limit at 

 Plymouth, has a superficial resemblance to R. corniculafa, but in its 

 bristle characters it is identical with R. macrostachya, which is frequent 

 in the Cape Cod region, and according to Oakes was abundant at the 

 same locality as jiis original material of var, immdata. R. corniculafa 

 with short stout bristles is unknown, on the other hand, north of 

 Delaware.

Carey, Boott and some other distinguished students of Carex con- 

 temporary with Dewey, recognized his C. tenera as identical with the 

 plant we now understand as C. strarninea Willd. (not Schkuhr). 

 Recent authors have, however, considered it as identical with the 

 larger primarily coastal plant with the perigynia about 10 nerved on 

 either face, — the plant described and illustrated by Boott as C. 

 strarninea, var. aperta. The recent accession by the Gray Herbarium 

 of the Carices of the late Chester Dewey has made it possible to gain 

 a clearing though somewhat surprising light upon this subject. Dewey 

 ordinarily indicated his type specimen by "(Mihi)" after the specific 

 name and later, very shortly before his death apparently, he added 

 to the labels the word "original" in a very dark ink. In the cover of 

 Carex tenera most of the material is clearly of one species. Two of 

 the plants are indicated by Dewey as the basis of his species. One 

 bears the label "C. tenera (Mihi). Sill. Journ. Vol. viii" and the later
