22 Description of three New Carices. 



* 



and memoranda may be trusted, with the " C. gracilis, Ehrh., 

 Upsal," in Schknhr's herbarium. 



Mr. Tuckerman, in his Enumeratio Caricum, (1843,) p. 19, 

 rightly remarks, that the C. loliacea of Schkuhr is scarcely that 

 of Wahlenberg and Fries ; and he inclines to the opinion, that 

 the specimen from which Schkuhr figured his C. tenella, out of 

 Hedwig's herbarium, was received by Hedwig from Muhlen- 

 berg, and therefore may directly represent the American plant. 

 This is not unlikely ; but Mr. Tuckerman does not appear to 

 have been aware that this species is also a native of the north of 

 Europe, and had been gathered at least as early as the year 

 1780. He justly remarks, also, that it is scarcely credible that 

 Schkuhr's figures 24 and 104, can belong to the same species. 

 I have already given what I believe to be the explanation of this 

 incongruity* 



It would therefore appear that the synonymy of the two species 

 in question should stemd as follows : 



1. C. loliacea, Linn.; Wahl ; FL Dan., t. 1403; Kunth, 

 (excl. syn. C. tenella and C. gracilis, Schk.,) not of Schk. Car. 

 No. 14, f. 91, nor Suppl. No. 47, p. 18. 



2. C. gracilis, Ehrh. ; not of Schk. Car., f. 24, nor of R. Br. 

 C. tenella, Schk. Car., f. 104 C. loliacea, Schk. Car. Supply 

 p. 18; not of Linn., etc. C. disperma, Dewey ; not of Kunze, 

 Car., t. 33.* •

 taller than the culm, 4-5 lines broad, rough on the margin. Sterile 

 spike l£-2 inches long : fertile spikes globular, occasionally sin-

* The figure which Prof. Kunze has given as C. disperma, from specimens gath- 

 ered on the Black Mountain of North Carolina by Rugel, is an entirely different 

 species; namely, the C. rosea, var. radiata, Dewey, (C.'neglecta, Tuckerm-) <> r 

 very near it— a plant which 1 have myself gathered on the mountains of Carolina, 

 very far south of the known range of the species for which this excellent Caricoio- 

 gist has unaccountably mistaken it.
