of: Ferns, with observations on the affinities of each genus.” The lat 
ter is continued in the numbers for July, August, and September; com- 
prising five of the seven tribes into which the Ferns of the first divis- 
ion, or Polypodiacee, (those with a vertical elastic ring to the spo- 
rangia,) are divided. The work exhibits infinitely more care and 
consideration than Presl’s Tentamen Pteridographia ; although some 
genera appear to be founded upon very slight technical distinctions. 
The first tribe, Polypodiee, is represented in the United States by 
Polypodium, Struthiopteris, Allosorus, (A. gracilis, J. Sm. = Pteris 
gracilis, Michx.) Notholena, (N. vestita, J. Sm. = Cheilanthes vestita, 
&c.) Teniopsis, (T. lineata = Vittaria lineata, Swartz,) ; 2d. Acrosti- 
chee, by a single Acrostichum ; 3d. Pteridee, by Pteris, Doodia, 
(Woodwardia Virginica, Swartz,) and Woodwardia, (W. onocleioides 
and W. thelypterioides, Pursh; but is the latter different from Doodia 
eee): ; the 4th. Aspleniee, by Scolopendrium, Asplenium, (of 
ium is considered a section,) and Antigramma, om nea 
um otenr penn Linn.,) but why was not the prior name of 
sorus retained for the genus? ‘The 5th tribe, Aspidiea, inobudial Ono- 
clea, [for the confirmation of Mr. Smith’s conjecture respecting the 
Rhagiopteris of Presl’s Tent. Pterid. see notice of the latter work in 
a former@mumber of this Journal,] Woodsia, Cystopteris, (C. fragilis 
and C. bulbifera,) Lastrea (= Nephrodium marginale, Michx., N»Gol- 
dianum, Hook. § Grev., N. Noveboracense, dilatatum, &c.,) and Polys- 
tichum, (Aspidium (Nephrodium, Michx.,) acrostichoides and A. aew- 
leatum.) It is but just that the name of Nephrodium, established by 
Michaux, should be employed, if employed at all, for some of the 
species originally comprised in that genus ; this name should therefore 
have been retained for either Polystichum or Lastrea, if the two last 
are really distinct genera. The October number is nearly filled with | |
