188 DAVALLIA. 



Hab. West Indian Islands, Martinique, Plumier ; Cuba, Poeppig ; 

 Bahamas, Swainson. Jamaica, Wiles, Mc Fadjjen, Purdie (White-Hall, 

 St. Thomas' in the East). — Quite distinct from D. tenuifolia, and appa- 

 rently peculiar to the new world (and confined to the trojiical inlands) as 

 the latter is to the old world. It is usually smaller than D. tenuifolia, far 

 more .slender, and delicate, of a much paler colour, with very elongated 

 narrow- cuneate or rather clavate segments. The ordinary height is a foot 

 (of Avhich the stipes is about half) ; but Mr. Purdie's specimens are two feet 

 long and exceedingly graceful. Schkuhr's figure, above quoted, is very 

 good, and it is strange that it should ever have been quoted as D. te- 

 nuifolia. Plumier's figure is characteristic, though coarse and the segments 

 too broad. 



85. D. retusa, Cav. ; erect, frond ample decompoundly 

 pinnate, pinnaj much acuminate, pinnules rhomboideo-lan- 

 ceolate tapering into a short petiole sometimes again pinnate 

 below, ultimate pinnules or segments broadly cuneate entire 

 or bi-trifid many-nerved, sori at the truncated apex generally 

 confluent so as to form a transverse linear involucre (resem- 

 bling that of Llndsaa). (Tab. LII. A..)— Cav. Prcel. n. 692.

Hab. Philippine Islands, {Camnilles) ; Luzon, Cuming, n. 411. — A tall 

 growing species, but not scandent, much branched, at least four times pin- 

 nate. Pinnules large, from the confluence of several lobes. The fructifi- 

 cations, if viewed from beneath, exactly resemble those of Lindsaa : but on 

 the back of the segment, the substance of the frond itself will be seen 

 to extend to tlie apex. The rachis is glossy chestnut brown : the I'rond 

 deeper brown, opaque and rather paler beneath. 



86. D. bifida, Hook, and Grev. ; rather small, roots tufted, 

 caudex obsolete, stipes erect, frond ovate or deltoid mem- 

 branous tender bright green tripinnate, ultimate pinnules 

 bifid or bipartite all of them linear cuneate glabrous trun- 

 cate and erose at the apex, sori terminal or nearly so, invo- 

 lucres transversely oblong entire. — Kaulf. Enum. Fil. p. 222.

Hab. Brazil, Cltamisso ; Minas Geraes, Langadorff (in Herb, nostr.) 

 Organ mountains, Gardner, n. 155 ; St. Catherine's, Macrae. — An elegant 

 and very graceful species, with the delicate appearance and rich green of 

 some Trichomaties , which also the narrow divisions of the fronds resem- 

 ble. Sprengel refers to this species " Lindscea virescens, Sw. ;" I know 

 not upon what authority, nor where that name is published. 



87. D. Goudoiiana, Kze. ; small, caudex slender creeping, 

 frond oblong-lanceolate acuminate membi'anaceous pinnate, 

 pinna; nearly sessile dee])ly bi-subtripinnatifid, the segments 

 narrow cuneate simple or bifid obtuse with a simple or 

 Ibrked vein, sori terminal often with a tooth of the frond 

 projecting on the outside, involucre subreniform, stijies short
