Hab. Mountains of Java, IHume. — A very handsome plant, accordinfi; to 

 Kunze's fij^iire; with pinnules resembling' those of D. Boryana, but tlie 

 plant is bipinnate. According; to my views of the genera of Ferns, this 

 cannot be referred to Lindsaa, for the involucre is not only much smaller 

 than the lobe which bears it (which the author above quoted considers the 

 outer indusium), but the colour and texture are quite different, as repre- 

 sented in Kunze's plate. The fructification, indeed, and the habit of the 

 species are in perfect accordance with the Odontoloma-gioup of DavalUa, 

 and the plant sliould not be separated from it. The veins in the magnified 

 figure not only meet at the sorus, as is common to others of this subgenus, 

 but they anastomose once below the sorus towards the apex of the pinna, 

 exhibiting an approach to reticulated venation. Blume observes of this 

 plant (ancl I am unacquainted with it myself, save from figure and descrip- 

 tion) " a Lindscca composita, Willd., facillirae distinguitur pinnulis raar- 

 gine sujieriori incisis, tenninalibus decrescentibus.'' 



*** Bipinnate, pinnules deeply pinnntifid. 

 65. D. Blumeatia, Hook. ; caudex creeping, stipes very 

 long triquetrous firm, frond ovate bipinnate, pinnae alternate 

 lanceolate attenuate, pinnules membranaceous sessile half- 

 oblong, from the npper edge cut down to the base in a ])in- 

 natifid manner into extremely narrow linear distant simple 

 or generally forked segments much dilated at the apex and 

 soriferous mostly toothed, vein solitary in each segment, in- 

 volucres minute transversely oblong smaller than the apex of 

 the segment subreniform. (Tab. LIV. A.) — Lindsaja tenui-

Hab. Parasitic on trunks of trees in the forests of Java, Bhime. Isle of 

 Leyte, Cumiw/, n. .309. — A most distinct, well marked and elegant species, 

 possessing the dimidiate pinnules so common to the present subgenus; 

 though at first sight appearing very diflcrent, on account of the long, narrow,' 

 deep segments; so narrow that the vein seems only to have a wing on 

 each side and running parallel with it. It is one of' those species which 

 exhibit a strong affinity with Lindscea as well as Davalliu ; but the circum- 

 stance of the involucre being nnicli .smaller than the terminal lobe, and
