propriately naintd it cahvscrns. Tlie veins, ami especially the involucres, 

 are quite glabrous, the pinna; are more distinctly petiolatc, and the whole 

 frond is more elongate.

 ceolate l)i])iniuite, stipes elongated, raeliis and veins ])iibcs-

 secondary or ])iiniules mostly ])etiolulate subdimidiato-ovate 

 obtuse ])innatifid chiefly on the ujjjier edge, lower lobes obo- 

 vate dee]) the rest short, all of them angulalo-dentate, veins 

 pinnated with a few scattered hairs beneath, involucres small 

 hair-cup--sha])ed in the axils of the teeth. (Tau. XLVII. A.)

Hah. Khasiya hills, north of India, (Jriffilh. Java ; pinnules smaller, 

 [Cmint llojf'mansei/fi). Ceylon, Mrs. Gen. Walker. /3. Isle of Ronin, 

 {Herb. Imp. Acad. Pclrop.) Luzon, Cuming, {n. Do). — Stipes 2-}^ feet long, 

 and the lower i)ortion of the frond 2 feet more. The ])rimary pinna; are 

 () — 8 inches long: the lower pinnules sometimes almost pinnated. The ge- 

 neral form of these pinnules assimilates the species with many of the group 

 or subgenus Microlepia, and it may be said to form the passage to them. 

 But I place it here on account of its general aflinity with the two ])receding 

 species, and its fronds being much less divided than in the true Microlepicc, 



54. D. loucliitidea, Wall. ; caudex creeping thick, fronds 

 ample tall tripinnate (primary and secondary jjinnules much 

 petiolated) every where glabrous coriaceo-membrauaceous, 

 pinna; large spreading ovato-lanceolate nuich and narrow- 

 acuminated deeply pinnatifid often pinnated at the base, 

 segments patent lanceolate (often very broad) acuminated 

 lobato-dentate, rachis and costa flexuose, veins pinnated, so- 

 ri solitary generally in the axils of the teeth near the margin, 

 involucres small half-cup-shaped. (Tab. XLVI. B.) — Wall.

 Mrs. Gen. Walker. — One of the noblest of the genus, from the size of its 

 fronds and the large and broad pinnules on long glossy petioles. These 

 fronds are much divided, the segments bearing copious fructifications. 

 Mr. J. Smith places this species in Microlepia, but if "habit is to be the 

 principal mark of distinction,'' as Mr. J. Smith observes, it surely is more 

 nearly allied to the original Saccoloma than to IMicrolepia.
