546 MR. C. B. CLARKE ON THE FERNS OF NORTHERN INDIA. 
otherwise, as to cutting and the needle-like hairs, it resembles Nephrodium setigerum, 
Baker. It varies greatly in size; fronds of 15-20 feet occur, while I have fronds 10 in. 
long in full fruit.—As to the synonymy of this fine species, Beddome’s figure quoted is 
the true plant, as is plain from his description; but it does not show the rhachises of ` 
the primary and secondary pinne paleaceous, which is the best character of the species. 
For the synonym, P. pallidum, Brack., Kew possesses authentic examples from Bracken- 
ridge. Several examples communicated from Malaya named Aspidiwm uliginosum, Kunze, 
are P. ornatum, Wall.; but the original description of Kunze (in Linnza, xx. 6) does not suit 
well. Cheilanthes pallida of Blume is cited as a synonym by Mettenius; but the example 
from Blume is Hypolepis, as Mr. Baker states. Polypodium trichodes, Reinw., Lowe, 
Ferns, ii. t. 2, means, I believe, Nephrodiwm setigerum, Baker ; but there is some P. or- 
natum about marked P. trichodes. For the Queensland locality there is an example 
communicated by Baron F. Mueller marked by him “ Polypodium rugulosum, var. hirsu- 
tum, reminds of P. tenericaule.” 
10. P. RvcosuLUM, Labill. Fl. Nov. Holl. ii. 92, t. 241. Rhizome creeping; stipe and 
lower part of main rhachis viscous-puberulous or viscous-pubescent, without pales or 
long hairs ; frond 3-pinnate.— P. punctatum, Thunb. Fl. Jap. 337; Hk. & Baker, 
Syn. Fil. 312; Benth. Fl Austral vii. 764. P. marginale, Wall. Cat. 322, only 
part of type sheet. P. rugulosum, Hook. Sp. Fil. iv. 272; Bedd. Ferns South. Ind. 
t. 170. Phegopteris rugulosa, Fée; Mett. Farngatt. Pheg. & Asp. 12. Hypolepis 
hostilis, Presl (at least as to Hohenacker's Nilgherry plants). Aspidium divisum, 
Wall. Cat. 393, partly. 
Very common in the hills from Chumba to Bhotan and Chittagong; alt. 1000-5000 
feet.—Distrib. South India, Ceylon, Malaya. Nearly throughout the tropics and south 
temperate zone, especially near the sea, extending to Japan, New Zealand, St. Helena, 
and Chili; not from continental Africa. 
This fern is also marked Polypodium viscosum, Roxb., and (in Herb. Kurz) P. viscosum, 
Zipp. ; but I do not know where those names are published. This fern has been con- 
fused with Hypolepis tenuifolia, which much resembles it in outline; but, besides the 
non-marginal sori, P. rugosulum may be distinguished by the very viscous rhachis. 
ll. P. suppiciratum, Blume, Fl. Jav. Fil 196, t. 93. Stipes tufted; frond 3—4- 
pinnate; ultimate segments small; texture thin, green, glabrous.—Bedd. Ferns 
Brit. Ind. t. 229; Hk. & Baker, Syn. Fil 340. P. conüfolium, Wall. Cat. 326.

From Nepaul to Bhotan ; alt. 6000—9000 feet, common. aue sect: Malay Peninsula and

Placed in Phegopteris by Sir W. J. Hooker; I have no doubt correctly. "Tho stipes ` 
are continuous with the rhizome; the sori are not terminal on the veins; authors |
