 sletjia group, though the luihit of the pluut is that of EmluvalUa. In the 

 var. ^. the texture is much more coriaceous, and there is an appearance, 

 though obscure, of the striae or pseudo-veins which arc so remarkable in 

 D. elegans. 



45. D. bullata, Wall.; small, caudex creeping clothed with 



copious subsqtiarrosc ferruginous subulate crinite scales, 

 frond deltoideo-ovatc submenibranaceous tripinnalc, fertile 

 specimens copiously bullate on the u])))er side, lower primary 

 pinnie subopposite ovate acuminate, ])innules lanceolate deep- 

 ly pinnatifid, segments entire or again inciso-pinnatifid, seg- 

 ments falcato-incurved linear acute, involucres oblong-ctip- 

 shapcd trimcate from the inside of the falcate segment arising 

 from the sinus of a small inner tooth. (Tab. L. B.) D. bul-

Hab. Nepal, Dr. Wallich, 18'21. Assam, Mrs. Mack. — A small plant 

 with a very long creeping caudex, densely clothed with dark brown scales. 

 Frond about a span long ; seen on the upper surface it presents a great num- 

 ber of oval swehings, which correspond with the sori on the opposite side, 

 so that if these fructifications were terminal on a narrow segment, they 

 would resemble those of Loxsoma. It is these nimierous swellings, no 

 doubt, that suggested the specific name to Dr. Wallich. 



46. D. Canaricnsis, Sm.; caudex long stout creeping 

 densely clothed with lanceolato-subulatc ciliated often cob- 

 webby scales, fronds deltoid decomjioundly pinnate subcori- 

 aceous (frequently pale green when dry) bullate on the u])per 

 side, primary piimie very broad, ultimate ])innulcs lanceolate 

 deej)ly pinnatifid, the segments oval or oblong subcimeate 

 acute soriferous simple or bearing a horn-like segment or 

 tooth on the outside, ultimate rachis of the pinna) winged, 

 involucres cuneato-cup-shaped truncate terminal on the mar- 

 gin. (Tab. LVI. A.) Sm. Tent. Fil. Gen. Dorsif. p. 14. Sw.

 Massou, Lout, Capt. Finlaj/, Dr. Lcinann. Tangier, Sallzmann. — A well 

 known Fern, having been long cultivated in our gardens under the appro- 

 priate name of Hares Foot Fern ; yet I am not aware that any figure has 

 been given of it, save the very indifferent ones of Magnol and Plnkenet. 

 Distinct as the species is to the eye, it is, like many other of the Ferns, ex- 

 tremely difficult to define the characters in words. It is, however, remark- 

 able for the broad deltoid form of the frond and its very compound ramifi- 

 cation : in the ultimate divisions and the penuliimate ones the raehises 

 becoming winged, and then the frond should be described as pinnatifid 

 rather than pimiatc.
