*** Fninda siiblcrnatc and pinnatifid, or bi-tripinnatifid. 



6. D. pedatn, S\v. ; caudex creeping paleaceous, fronds 

 sti})itate very coriaceous small deltoideo-cordale somewhat 

 5-angled tripartito-pinnatifid, the segments patent but inclin- 

 ing upwards oblong obtuse, fertile ones crenato-dentate, the 

 two lower primary divisions obliquely ovato-acumVliate, invo- 

 lucres small semiorbicular or nearly orbicular alternating with 

 the teeth of the serratures placed close to the margin and 

 pointing to it, stipes elongated chaffy below^ (Tau. XLV. A.)

Hab. Mauritius, and Marianne Isles (Swartz), and Bourbon, Wallich, 

 Dojer, Carmichael. Singapore and Sylliet, Wallich. Ceylon, abundant, 

 Mrs, Genl. Walker. Java, Blume. — This varies in size from 2 — 6 inches, 

 l)ut scarcely in form, which appears to me very constant, the fertile spe- 

 cimens however being always the largest and the most divided. 



7. D. intermarginalis, Bl. ; " frond on a long stipes ovate 

 deeply pinnatifid coriaceous glabrous, the segments linear- 

 oblong obtuse crenated in the middle and at the apex, the 

 lowest ones auricled below, involucres reniform intermargi- 

 nal, stipes compressed glabrous, caudex creeping paleaceo- 

 squamulose." Bl. En. Fil. Jav. p. 230. 



Hab. Trees in the interior of Java, Blumc. " Distinguished from the 

 D. pedata, Sm., D. subimbricata, Bl. — see D.pedata, supra, — and D. scs- 

 silifolia, by the sori being within the margin (interraarginal), and not nt 

 the margin." 



8. D. sessilifolia, Bl. ; "frond subsessile cordato-oblong 

 pinnatifid subcoriaceous glabrous, the segments oblong-linear 

 obtuse crenulate soriferous at the apex all of them approxi- 

 mate, the lowest ones wider (not longer) subpinnatifid, sori 

 reniform, caudex creeping ferrugineo-crinite." Bl. En. Fit. 

 Jav. p. 231. 



Hab. On trees, mountains of Salak, Java, Blume. " From the preceding- 

 species (Z). pcdata, &c.) this is distinguished by the frond being on a short 

 stipes, by the ovato-oblong circumscription, almost membranaceous texture, 

 and by the lowest segments being rather shorter than the rest, auriculato- 

 pinnatifid at the lower margin." 



9. D. serrata, Willd. ; "fronds ternate, lobes pinnatifid, 

 the segments of the sterile frond linear-oblong obtuse serrat- 

 ed, those of the fertile frond linear-lanceolate acute deeply 

 serrated, caudex creeping." Willd. Sp. PL v. p. 4(57. — Hu- 

 mata trilbliata, Cav. Prwl. 1801, n. 680.
