AUTHENTIC CYPERAVEE OF LINN EUS. 315 
ERtoPHORUM POLYSTACHION, Sp. Pl. ed. 1, p. 52, n. 2. 
One sheet, marked “ polystachyon ” in Linneeus’s hand, is 
ER1OPHORUM ANGUSTIFOLIUM, Roth. 
The species of Linneus, EF. polystachion, has been divided into 
three very closely allied European species, of which E. angusti- 
folium, Roth, is the most plentiful. It is very difficult to 
maintain the distinction between the three on North-American 
material. Under these data, the proper plan would appear to 
be to retain the Linnean name £. polystachion for the mass of 
the species (Z. angustifolium, Roth), and to call the two sub- 
species E. gracile, Koch, and £. latifolium, Hoppe. Unfortu- 
nately a considerable number of botanists prefer to apply the name 
E. polystachion, Linn., to the subspecies EZ. latifolium, Hoppe. 
This being so, botanists appear agreed, by a very large majority, 
to drop the Linnean name; it cannot be applied to the prevalent 
form without the explanatory addition of E. angustifolium, Koch. 
ERIOPHORUM ViRGTNIcUM, Sp. Pl. ed. 1, p. 52, n. 3. 
One sheet, marked “ virginicum ” in Linneus’s hand, is 
ErtIoPHorvuM VIRGINICUM, Linn. 
The plates cited. Pluk. Alm. t. 299. fig. 4, and Morison, Hist. 
sect. 8, t. 9. fig. 2, are both right. 
Eriophorum virginicum, Linn., is (altogether) Goon. 
ERIOPHORUM ALPInum, Sp. Pl. ed. 1, p. 53, n. 4. 
One sheet, marked “ 4. alpinum ” in Linneus’s hand, is 
ERIOPHORUM ALPINUM, Linn. 
The plate cited, Scheuchz. Agrost. t. 7. fig. 4, may be right, 
but avails nothing. 
Eriophorum alpinum, Linvn., is (altogether) Goon. 
[In the discussion which followed the reading of this paper, I 
was convinced by Mr. Carruthers and Mr. Daydon Jackson that 
the common plan of citing ‘““Scnanvs, Linn. partim (or emend.)” 
must be retained; though the meaning cannot be understood 
without the addition ‘‘ Benth. Fl. Austral. vii. p. 352.” Also, 
Mr. Carruthers has since showed me the plant in the British 
Museum whence Sloane, Jamaica, t. 74. fig. 1, is taken; this 
plant is Cyperus ferax, L. C. Rich. (a species which, J fear, we 
are bound to eall Moriscus Pohlianus, Nees, if we place it in the 
genus Mariscus). Sloane’s plate is so badly engraved (from the 
drawing prepared for it) that T am not at all surprised that I was 
confident that it was not taken from Mariscus Pohlianus.— 
C. B. C., 17th Sept., 1894.] ,
