deal tlie api)earance of Dick.ionia vicutaria, S\v. and is, I fear, often coii- 

 ioiinded with it. Bliinie mentions a var. " pinnulis sccuudaiiis sursum 

 subiuciso.ereuatis deoisuni integeniniis." 



71. \">. pro.vimii, Bl. ; " Irond (ample) trii)innate glabrous 

 soincwluit downy on tlu; cost;u beneath, pinuie alteniate re- 

 mote, pinnules laneeolate very mueli aeinninated, seeondary 

 ones sessile traj)ezoideo-ol)long obttise ineised, superior ones 

 entire confluent, lower ones slightly pinnatifid, sori puncti- 

 form placed near the margin semiorbieular, raehis and stipes 

 a little rough." 131. En. Fil. Jav. p. '238. 



Hal). Java, Jiluiiic. — "Closely allied to D./hiccidu, Br. {D. poli/podinidt's 

 nob.) : but distinct in the siibcoriaeeous frond and the longer caudate ])in- 

 nules.'' In the province of Bantam the same author finds a var. " B ;" 

 with the secondary pinnules rather remote, obhmg-obtuse, doubly inciso- 

 serrate, — (an species ?) 



72. D. Jamaiceiisis, Hook. ; frond am])le tripinnate flaccid 

 glabrous or with a few scattered hairs beneath on the veins 

 and costa and raehis, primary and secondary pinn;e oblong 

 moderately acuminate, ultimate pinnae subdimidiato-oblong 

 obtuse deeply ])innatifid the segments longer on the upper 

 margin all of them ovate slightly falcate obtuse dimidiate 

 entire at the lower margin 2 — 3 lobed at the superior one, 

 sori at a little distance from the margin on a lobule near the 

 sinus, involucres suborbiculari-renifbrm (!) flat. — Davallia 

 flaccida, Hook, ct Am. in Bot. of Beech. Voy. p. 101 in 

 part. 



Hab. Jamaica, iVi/es, Dr. J Bancroft, UlcFadi/eu. Oahu ? Jiceclui/.— A 

 species so much resembling Z>. poli/podioidcs, that I ean point out no mark 

 of distinction save the difl'erent form of the involucre, aud that, instead of 

 being- half-cup-shaped as in the Microlepia group, is broad and flat and 

 between orbicular and reniform, quite free at the apex and sides and attached 

 only by a rather broad base. This is invariably the ease in three speci- 

 mens received from three dilTerent collectors in Jamaica ; and on carefully 

 inspecting one of my specimens of supposed Dar. jmli/podioidvx from 

 Oahu I find a similar involucre; but being young the form is not so clearly 

 and satisfactorily defined as in the West India plant. 



73. D. iric/iosiicha, Hook. ; frond ample submembrana- 

 ceous bi-tri ?-pinnate, primary pinna) a foot long the raehis 

 winged above, ultimate pinnnc or pinnules sessile obliciuely 

 cinicate at the base oblong-lunceolate acuminate pinnatifid 

 deeply so toward the base, upper inferior lobe the largest, all 

 of them ovate obtuse nearly entire or crenato-lobatc sliglitly 

 hairy above densely and minutely ])ubescent almost conceal- 

 ing the veins beneath, sori small rather distant from the mar- 

 gin, involucres small half-cu])-sha])ed very downy. — Microle-
