7H PICRSONIA. 



Hal). Pacific Ules, J'orsler. — I liave seen no s)ieciinciis of lliis from 

 tlio " Pacific Isles,'' save Forstei's orifj;inal ones in the Bantsian herharinin ; 

 and as far as can he jii(lf>ed from lliem, and indeed from the description 

 and (ifrnrcs above quotetl, it may safely be referred to D. cirularia, which 

 \\e V\u>\\ throws at Cocos Island. Swartz describes a donble indusium, 

 which, if cornet, wonld induce us to refer the species to the Balantium di- 

 vision : but Berniiardi's figure represents it as an entire cup. 



35. I). Molticcavn, V>\ ; " frond Iripinnatifid coriaceous 

 .somewhat downy beneath, ])inntc op])osite oblongo-lanceo- 

 hite acuminate, ]>innule.s lanceolate rather obtuse deeply 

 pinnatifid, segments dimidiato-ovate obtusely toothed on the 

 ii])])er margin, rachis and scandent stipes aculeate." Bl. Fil. 

 Jar. p. 239. 



Ilab. Mountains of the Moluccas, Blame. — " Distinguished from D.flnc. 

 cida, 8w., by the aculeate rachis." 



3(). D. .'icdnde />.<!, Bl. ; frond tri))innatifid or supradecom- 

 pound membranaceous glabrous, pinna) opposite oblongo- 

 lancoolate acuminate, pinnules lanceolate rath(n- obtuse deeply 

 ])innatiftd, segments dimidiato-ovate obtuse bluntly inciso- 

 dentate, rachis and scandent stipes aculeate." Bl. Fil. Jav. 

 p. 240. 



Ilab. Lofty mountains of Java. On the volcanic mountain, Gede, Pal- 

 lasarie, &c. Bknne. — " Differs from the preceding (/>. Moluccnna) in the 

 flaccid frond and in the larger teeth of the segments." 



37. D. Javanica, Bl. ; " frond decompound coriaceous, at 

 the costa beneath and on the rachis hairy, pinna; alternate and 

 the pinnules (which are nearly opposite) ovato-oblong very 

 acuminate, secondary subrhombeo-lanccolate acute deeply 

 ])iiniatifid, the segments cuneato-linear rather obtuse une- 

 qually and obtusely dentate bearing sori in the sinuses." BL 

 Fil. Jav. p. 240. 



Hab. Mountain woods of Java, Blume. — " Dicksoniajlaccida, Sw., dif- 

 fers in the segments of the frond being broader and more obtuse." 



38. D. distenia, Kze. ; " frond ample remotely tripinnato- 

 ])innatifid slightly hairy at the veins on each side, primary 

 piniue ovate and secondary sessile subopposite patent oblong 

 aciuninate, pinnules luiequally ovato-oblong obtuse dee])ly 

 pinnatifid, segments oblong subfalcate sinuato-dentate bear- 

 ing sori in the sinuses, sori transverse, sti])es and rachis a little 

 hairy furrowed above." Kze. Anal. Plcrid. p. 39. Limuca, 

 r. iii. p. 145. 



Hab. Xalapa, Mexico, Sihiedc. — From the " transverse " sori and the 

 " indusium proprium semilunatun), marginale, brevissivium," I should 

 have been disposed to refer this to the Balantium-gnmp ; but the author 

 compares it with J), rubiginnsn, D. anthrisvifidia and D. cornnta, among 

 which, the plant being wlndly unknown to nie, I have thought it best to 

 pliicc it.
