156 DAVALLIA. 



13. D. vestita, Bl. ; caiidcx creeping paleaceous, stipes 

 elongated paleaceous with lanceolate chaffy scales, fronds co- 

 riaceous (a span or more high) bipinnate, pinna; lanceolate 

 subpetiolate pinnatifid the lowermost ones at the base again 

 pinnate inferior segments the largest, all of them serrato-den- 

 tate, rachis and costa beneath beset with broadly ovate obtuse 

 chaffy appressed subpeltate scales, fructifications small in the 

 axils of the teeth, involucres suborbicular rather broader than 

 long. (Tab. XLI. C.) — Bl. in En. Fll. Jav. p. 233. 



Hab. Trunks of trees, mountains of Java, Blwne, Mr. Millett. — This is 

 quite distinct from any species with which I am acquainted, especially in 

 the presence of copious rounded obtuse scales appressed to the under side 

 of the frond upon the racLis and costa. The stipes is about a span long : 

 the frond equally lonj^, tripinnate below, the primary piunas numerous re- 

 mote. Blume says of it, "Z>. «//>m<E, nob. habitu similis, sed fronde ma- 

 jori bipinnata diversa;" and he indicates two varieties; '"'' var. B; frond 

 larger, lower pinnae bipinuatifid, pinnules oblong-lanceolate rather obtuse, 

 segments subinciso-senate." — " Var. C. frond more slender, lowest pinnae 

 subbipinnatiiid, pinnules (of the lowest pinnae) only inciso-serrate." The 

 latter inhabits Moluccas and the Celebes Islands. It is the former state 

 apparently that we possess from Mr. Millett, and which we have here 

 figured. 



14. D. hipinnattfida, Bl.; "bipinnate (quinquangular ova- 

 to-oblong) coriaceous glabrous, lowest pinnae bipinuatifid, 

 pinnules lanceolate acuminate coarsely serrated, the segments 

 (or secondary pinna?) linear acute crenulate, crenules each 

 with a single sorus, involucres subreniform, rachis margined, 

 stipes terete glabrous, caudex creeping paleaceous." Bl. En. 

 Fil. Jav. n. 234. 



Hab. On trees in mountain woods of Java, Blume. "Priori {D. vestit(B) 

 maxime afhnis, pinnulis acuminatis et grosse serratis distincta." The au- 

 thor does not notice the numerous scales, which are so striking a feature in 

 the preceding. 



(D. lepida, Pr. Tent. Pterid. p. 128, — no description. Presl 

 places it in the same section with D. pedata, and between 

 D. serraia, Willd. and D. pectinaia, Sm.) 



Subgen. II. Leucostegia. Involucres orbicular or reniform, thin, 

 membranaceous and usually pale coloured, generally situated in 

 the sinus of the teeth or segments, the sides as ivell as the apices 

 free. Fronds small or ample, membranaceous, compoundly di- 

 vided firstly in a pinnated manner, then pinnatifid. Caudex 

 long creeping generally scaly. Hook. Gen. Fil. Tab. LII. A. 

 Genus Leucostegia, Pr., J. Sm. {in part). 



15. D. immersa, Wall.; caudex creeping downy and fibrous 

 with slender roots (not scaly), frond stipitate ovate in circum- 

 scription membranaceous opaque tripinnate, pinnae pinnatifid
