Hah. Novtlicrn India, Slieopore and Nepal, Wallich. Assam, Mrs. 

 Mack, Griffith, HfaJor Jnihius. Khi\s\y a, Griffith, Mr. Edtjcirnrlh. — A 

 very remarkahlo plant, apparently common in Northern India. Tlic invo- 

 lucres are larpe and lie singnhirly close to the patjina of the segment, and 

 on that side which is pale and slightly convex (from the curvature of the 

 margin), peculiarities which characterize the anterior or up))crside in most 

 fronds : so that, as Prcsl well observes, unless you look carefully at the ra- 

 chis and stipes, you would say that the Irnctification was on the superior 

 side instead of the inferior. Stipes 4 — 6 or 7 inches high, sometimes a foot 

 high. Frond about the same length. 



16. D. ? itodosa, Hook.; "frond tripinnate inembranacc- 

 ous furfuraceous on both sides of the veins, pinnules sessile 

 (chaffy beneath at their insertions) oblong-lanceolate, secon-

 obtuse, lowest ones inciso-serratc or at the base again subau- 

 riculate, sori solitary submarginal, rachis nodose above at the 

 insertion of the pinna; and ferrugineo-tomcntose, stipes slight- 

 ly rough or glabrous paleaceous below." BL — Aspidium no-

 — Of this plant, I regret to say, I know notliiiig, but from the remarks of 

 Blum'~ and Presl, and the figure of the latter author. Blume arranges it in 

 Axpidiwn, and expresses no doubt of the propriety of so doing. Presl makes 

 a distinct genus of it, and places it between Ci/xtoptcris and Lmcostegia. 

 Judging from his figure, I do not see how it differs from Davallia, but he 

 says " iioccc genus Ci/ntoplcridi valde affine est, differt sons in venulis api- 

 CJilibus;" — and under Lcucnstei/ia he says, " Acrophoro aflinissimum est." 

 Mr. J. Smith docs not appear to notice the genus. Link (in Fil. Spec. 

 Hort. Keg. Berol. cult. p. 41) unites it with Ci/stopteris.
