character to the rachis. There are no strise or pseudo -veins, as in D. ele- 

 (jans and D. elata, and the involucres are inserted below the apex of the 

 teeth or lobules. 



42. D. polyanilia, Hook. ; tall coriaceous, frond 3- 4-pin- 

 nate, pinnae distant ovato-lanceolate acuminate, lower pin- 

 nules deeply pinnatifid almost to the rachis petiolate, upper 

 ones and the segments of the pinnules oblong rather acute, 

 ultimate ones decurrent so as to form a winged rachis, all of 

 them crenato-serrate, veins pinnated no stria?, each lobule 

 bearing an oval truncated involucre rather considerably be- 

 low the apex with a very short erect tooth on the outside (of- 

 ten obsolete). (Tab. LIX. A.) 



Hab. Sincapore, Thos. Lohh. — I was at first disposed to refer this to 

 the D. decurrcns,]\\?,i described (Z). ahila, J. Sm. not BL), but I feel satis- 

 fied that it is different. It is of a more rigid and coriaceous texture, more 

 glossy; the winged rachis is only confined to the upper segments; the low- 

 er segments are more deeply pinnatifid, and the involucres (which are 

 copious in both) are a little different in form, and more distant from the 

 margin. 



43. D. Vogelii, Hook. ; caudex long creeping stout dense- 

 ly clothed with shaggy hair-like subulate fimbriated scales, 

 frond rather small deltoid-ovate submembranaceous 4-pin- 

 nate, pinna? ovato-lanceolate, ultimate pinnules lanceolate 

 decurrent acute sharjily pinnatifid segments acute incurved 

 not striated, involucres half oval truncated inserted below the 

 transverse sinus of the segment (or tooth). (Tab. LIX. B.) 



Hab. Fernando Po, Dr. Vogel. — A rather small plant: frond scarcely a 

 foot long, yet in habit and ramification and form of the pinna; and seg- 

 ments so much resembling D. elet/ans, that I can point out no other marks 

 of distinction, save the more membranaceous texture, the total absence of 

 stria; or pseudo-veins, and the longer segments or teeth extending far be- 

 yond the involucre. 



44. D. Griffitlnana, Hook, ; caudex long stout creeping 

 clothed with copious pale-coloured shaggy fimbriato-pilose 

 scales, frond deltoideo-ovate subcoriaceous tripinnate, pinnae 

 acuminate, pinnules oblong-lanceolate petiolulate obtuse ob- 

 liquely cuneate at the base pinnatifid, lower ones again pin- 

 nate, lobes short obtuse or retuse almost obsolete on the lower 

 margin, involucres flat orbiculate the upper half free placed 

 at a distance from the apex of the lobules and chiefly upon 

 those of the superior margin, rachides (except the primary 

 ones) winged, stipes elongated. (Tab. XLTX. B.) — jS. more 

 coriaceous, with a faint appearance of strioe or pseudo-veins. 



Hal). Northern India, Assam, n. 910, and /3. Khasiya, Mr. Griffith. — I 

 do not know any species with which this can be confounded, if the blunt 

 segments or lobules of the pinnules be considered, and the form and situa-
