Himalaya, alt. 2000-7000 feet, from Gurwhal to Bhotan, common. Khasia, alt. 2000- 
4500 feet, frequent. Chota Nagpore, alt. 2000-3000 feet.—Distrib. Malay Peninsula,

 Verr partial to limestone: as also Parish notes of the allied NW. Parishii. A. pilosulum, 
Wall., is much dissected, the segments more remote than usual. A. subdiaphanum, 
Wall, is very thin in texture, less pilose than common; some of the involucres when 
young are attached laterally on the vein. On the whole N. crenatum varies little, and 
there are no disputed examples. 
REESE Frond 2—93—4-pinnate, large ; involucres often caducous. 
22. N. PULVINULIFERUM, Hk. & Baker, Syn. Fil. (2nd ed.) 500. Stipe and main rhachis 
with many chestnut or black subulate persistent scales, often 1 in. long; surface of 
frond glabrous; secondary pinnz usually soriferous in their upper portion only.

Usually a fine compound fern as described by Bakers, 7. e. but not rarely the fronds in 
fruit are under a foot long, i. e.—.N. Buchanani. 
23. N. SIKKIMENSE, C. B. Clarke. Stipe and rhachises with ovate acute chestnut or 
blackish seales; frond 1-3 feet, oblong-lanceolate, glabrous, sub-3-pinnate, texture 
herbaceous, thin ; tertiary pinn: cuneate-oblong, serrate ; involucre thin, persistent, 
_ strictly nephrodioid.— Polystichwm sikkimense, Bedd. Ferns Brit. Ind. t. 197. As- 
pidium sikkimense, Hk. & Baker, Syn. Fil. 256. 
Sikkim, Mon Lepcha, alt. 10,000—12,000 feet; T. Thomson, Sir J. D. Hooker, C. B.

One of the most beautiful of ferns. Mr. Baker préferred Beddome's picture of the 
.involueres to the specimens when he referred the species to Aspidiwm. I collected large 
quantities of this fern (all at the well-known locality); but, never imagining that it could 
have been supposed a Polystichum, have distributed it under the name Lastrea bella, 
- nov. Sp.
