MR. C. B. CLARKE ON THE FERNS OF NORTHERN INDIA. 419 
Nepaul and Kumaon, alt. 6000-8000 feet; very restricted in area and nowhere 
common. 
There is no instance in the Kew Herbarium where capsules are produced on both 
sides of a nerve. The involucre is large, thin, early dehiscent from the outer edge, often 
becomes doubled or folded, and generally becomes totally reflexed, so that the sori are 
seen one side of the vein, the involucre the other. H. C. Levinge notes that A. erectum, 
Bory, var. trapeziforme, Bedd. Ferns South. Ind. t. 184, hardly differs; it is rather 
less acutely serrate, and the lower margin of the pinnæ is more cut away at the base : 
I see very little difference. Beddome’s figure is exceedingly good, and his magnified 
view of the sori also excellent; the lowest involucre is shown across the vein (as it 
usually appears); but Col. Beddome shows the capsules peeping from under the involucre 
on both sides of the nerve, which I have never been able to see.—4. Wichure, Mett. in 
Ann. Mus. Lugd. Bat. ii. 237, is doubtfully distinct, by the more creeping rhizome with 
distant stipes. It is a Huaspleniwm, and (except as to the rhizome) identical with 
A. longifolium. | 
«4| Pinne unequal at base, the lower margin narrowed at the base, or more or 
| less cut away. 
ll. A. CRINICAULE, Hance, in Ann. Sc. Nat. sér. 5, v. 254, Frond linear, 1-3 feet ; 
rhachis with lanceolate-setaceous scales; pinnæ 1-1} in., lanceolate subfalcate, 
unequally cuneate at the base, serrate or pinnatifid less than halfway to the midrib ; 
sori linear, oblique on either side the midrib.—Hk. & Baker, Syn. Fil. (ed. 2) 208.

Tufted, usually much larger than A. planicaule. Out of the Indian material now 
accumulated at Kew it is possible to match exactly Hance’s type specimen of his 
A. crinicaule. Hance’s smaller specimens with very entire pinne cannot as yet be 
matched from India. Some of C. B. Clarke's Jaintea specimens have the pinnz deeply 
pinnatifid, and should perhaps be referred to 4. planicaule.-—The rhachis has numerous 
lanceolate setaceous scales, and often also ovate fimbriate scales. 
12. A. rancATUM, Lamk. Encycl. ii. 306. Rhizome tufted ; frond linear-lanceolate ; 
rhachis glabrous or very sparingly scaly ; pinnze petioled, 2-4 in., lanceolate caudate 
serrate ; nerves close, flabellulate ; sori linear, flabellulate nearly to the margin.—
