mention, however, the beak, the very short beak given by 

 Willd. which is a very good character in this species. The 

 whole plant is rather glaucous green before the fruit is en- 

 tirely mature, and is thus coloured in Schk. The upper 

 spikes are sometimes more clustered than in the fig. of 

 Schk- or ttan the descriptions would imply. Its peculiar 

 roundish-ovate approximate fruit, entire at the mouth, ex- 

 tremely short beaked and re-curved, becoming of a dull yel- 

 low in full maturity, and its glaucous green readily distin- 

 guishes it from the other species in the same sub-division in 

 Ph. and Eaton. 



Pursh gives C. lenticularis, Mx. as the same plant. The 

 specific name of Mx. is entirely opposed, however, to their 

 identity. The fruit of C. granulans can scarcely be said 

 to approach towards the lenticular form. The description 

 of the leaves and culm does not correspond to those of C 

 granularis. The remark of Mx. that his C. lenticularis. is 

 related to C. panicea, will not justify the conclusion of Ph. 

 Persoon was more cautious, and merely asks whether the 

 two plants are the same. 



At the elevated marsh in Storkbridge, Dr. E. Emmons 

 found a Carex, growing in abundance, which seems to be 

 the C lenticularis, Mx. The locality is similar to that at 

 which Mx. found the plant, "especially about Swan Lake.''' 

 For comparison. I will give the description of Mx. C len- 

 ticularis. "Foliis angusto-longis. culmo gracili triquetro 

 subsequalibus : spiculis fem. pluribus, pednnculatis, oblon- 

 gis ; masculae unica : capsulis lenticularibus, brevi-ovatis, 

 muti<is." Flor. Bor. Am. 2. p. 172. 



Our plant has narrow leaves, long and about equal to the 

 slender three-sided culm : staminaie spike solitari^^ lanceo- 

 late, with brown oklong obovate scales ; pistillate spikes two 

 or three, peduncled, pendulous ; bracts long as the cidm with 

 very short sheaths ; fruit ovate, compressed, lenticrdar, five- 

 nerved, scarcely rostrate, shorter than the large brown carin- 

 ate ovate-oblong scale. 



It is related to C. panicea L., but more nearly resembles 

 C- liniosu L. From the former it dilFers in many respects; 

 from the latter, it differs in the form of the stammate scale, 

 and in the form and length of the pistillate scsIp and in the 

 shape of the fruit. It approaches more nf:grly to C, limosa 

 /3 irrigua, Wahi. Buf it differs in so many respects, that 

 it is probably a different species. It must be closely rela-
