CVSTOI'TEUIS. 199 



Such, in our view of the sulijcct, is lY.v range and such the synonyms of 

 this plant, and if it were worth the hibour of investigation, the hitter might 

 be increased two-fold. Desvaux adds live names of Poiret to the list of sy- 

 nonyms, and among the sixteen species of Ci/sinpUris, given as such, by 

 that author, probably several might with propriety be referred to the present.

Hab. Alps, chiefly in the South of Europe. England ; on a wall (since 

 destroyed) at Low Layton, Essex, T. F. Forster, Esq. — An elegant bright 

 green species, very difl'ercnt from the preceding, although nearest to some 

 small states of vac. a, and diflicult to be defined in words. 



3. C. Tast?ianica, Hook. ; small delicate, stipes short and 

 rachis capillary, fronds oblong pinnated, pinnae laroadly ovate 

 inciso-lobate upper ones decurrent lower ones ])etiolate and 

 pinnalifid the segments ovate obtuse entire or slightly tooth- 

 ed, sori few very minute, involucre ovate acuminate, rachis 

 winged above. 



Hab. Van Diemen's Land, R. Gunn, Esq. — I was at one time disposed 

 to refer this to one of the states of the var. dentata of Cfraijilis, but the 

 fact of Mr. J. Smith having received from the same country, though from 

 a different source, an exactly similar plant, together with the delicate habit, 

 large (comparatively) and broad, little divided pinnae, and minute fructifi- 

 cations, induce meto keep it distinct. Caudex slightly creeping. Whole 

 plant, including the stipes, 4 — 5 inches high. 



4. C. hnlhifera, Bernh. ; frond broad-lanceolate or ovato- 

 lanceolate and elongated bipinnate, primary pinna; horizon- 

 tal oblong-lanceolate from a broad base acuminated, pinnules 

 oblong obtuse spreading pinnatifid toothed or pinnalifid, the 

 segments entire or of the base of the lowermost j)inn;c almost 

 again pinnatifid, rachis not winged, that of the pinna' often 

 bulbiferous beneath, involucre subglobose. — Aspidium bulbi- 

 ferura, Sw. Syn. Fil. p. 29. ^c//A7/. FiL p. 55, /. 57, [e.vcel-

Hab. N. America, chiefly in the middle United States and Canada. — I 

 have not seen this from a locality further south than Kentucky, except in 

 one instance, from Virginia {Mr. Greene), nor further north than about
