44.6 MR. C. B. CLARKE ON THE FERNS OF NORTHERN INDIA. 
Sect. IV. Microlepia. Rhizome very shortly creeping; stipes tufted, not articulated 
from the rhizome; involucre triangular or subsemicircular, not quite marginal. 
. 12. D. HookERIANA, Wall. Cat. 2684. Pinne narrowly oblong, acuminate, entire or 
crenate-serrate, not pinnatifid; ultimate veinlets parallel.—Hook. Sp. Fil. i. 172, 
t. 47 B; Bedd. Ferns Brit. Ind. t. 101; Hk. & Baker, Syn. Fil. 97.

Simons.—Distrib. South China. "m 
Frond thinly hispid on both surfaces; pinnze often auriculate at base on the upper ` — 
margin, the rhachis beneath laxly villous, not closely strigose, subhirsute. Baker and 
Beddome give Kumaon as a locality for this species. There is no example thence (there 
are only four Indian examples altogether at Kew); it seems not probable that it was 
ever collected there. Wallich is not safe in the matter of localities, as he in several 
cases mixed Kumaon and Tenasserim collections together, sorted them by hand and eye, 
and distributed sheets compounded of Kumaon and Tenasserim species. 
13. D. PLATYPHYLLA, Don, Prodr. Fl. Nep. 10. Large, glabrous, bipinnate, tripinnatifid ; 
secondary pinnæ coriaceous, shining on both surfaces, lanceolate-linear, often cau- 
date.—Hk. & Baker, Syn. Fil. 99.. D. lonchitidea, Wall. Cat. 240; Hook. Sp. Fil. i.  .

Himalaya; from Nepaul to Bhotan, alt. 83000-5500 feet, plentiful in Sikkim. Khai 
alt. 3000-4000 feet.—Distrib. Mts. of Malabaria and Ceylon. 
Rhizome horizontal; the stipes approximate near its apex. Young frond with lax E 
long hairs scattered often on both surfaces; "roug frond and fully developed barren ` — 
frond altogether glabrous. e 
There is a very fine new species, D. Kurzii, C. B. Clarke, obtained by Kurz in Burma, ` — 
uniformly pubescent beneath, the ultimate segments triangular, subobtuse, with bluntish — 
sera tures, otherwise like D. platyphylla. 
14. D. vnoPHYLLA, Hook. Fil. Exot. t. 19, note. Large, bipinnate, tripinnatifid, secon- — ` 
dary pinnze coriaceous, shining above and beneath, but pubescent on the rhachises ` 
beneath, lanceolate-linear, very finely cordate.—Hk. & Baker, Syn. Fil. 99, not of —

Bhotan, Griffith, nos. 1449, 2795; 4 sheets in the Kew Herbarium. (PLL) 
Closely allied to D. platyphylla. Ultimate segments lanceolate, secund, quite glabrous S 
beneath. 
15. D. MARGINALIS, Hk. & Baker, Syn. Fil. 98. Pinne narrowly oblong-linear, sub- 
entire, crenulate or pinnatifid halfway to the midrib, but not more deeply; rha- 
chises beneath strigose, subhirsute; veinlets and involucres more or less villous.— 
D. scabra, Don, Prodr. Fl. Nep. 9. D. villosa, Wall. Cat. 244; Hook. Sp. Fil. i.
