difference in cutting between the Decean and East Bengal examples; the figure of Sir 
W. J. Hooker represents the East Bengal type; the figure of Col. Beddome represents 
the Chota Nagpore type. Chota Nagpore is, phytographically as well as geographically 
and geologically, the north-east extremity of the Deccan Plateau. SE.

denudate when old). | 
5. CH. SUBVILLOSA, Hook. Sp. Fil. ii. 87, t. 98B. Frond elongate-lanceolate; the lowest 
pair of pinnz distant, narrower than the pair above; stipe shorter than the frond, 
glabrous, with a few broad-lanceolate uniform-coloured scales near the base ; rhachis 
of primary pinne with crisped woolly salmon-coloured hairs beneath, but no scales; 
involucre continuous, slightly crenulate, not fimbriate on the margin.—Mett. Farn- 
gatt. Cheil. 48; Bedd. Ferns Brit. Ind. t. 142; Hk. & Baker, Syn. Fil. 137. 
North-west Himalaya; Pabur Valley and Kotghur, near Simla, Zdgeworth. 
Scales of the rhachis light-chestnut-coloured or scarious. Main rhachis glabrous 
beneath, the partial rhachises woolly. Pinne often 8-10 pairs, separate, the lower 2 in. 
apart. Involucre as in Pellea, to which this species might be referred. In this and the 
neighbouring species of Cheilanthes the margin of the frond is at first reflexed, con- 
tinuous, becoming in the age of the fruit beaded or broken up; in Pellæa the margin is 
continuous in age; the distinction is very small.—Col. Beddome expresses an opinion 
that this species is only a form of Ch. farinosa; but he has perhaps never seen it, his 
figure being taken from Sir W. J. Hooker’s. There is no powder on the examples, of 
which, however, there are but 2 sheets at Kew. 
6. CH. ALBO-MARGINATA, C. B. Clarke. Frond lanceolate; the lowest pair of pinn® 
usually more developed than any superior pair; stipe shorter than the frond, 
glabrous, with many lanceolate white-margined scales; pinnz, when young, densely 
scaly beneath, often with yellow powder also, but not hairy, when old usually scaly 
beneath on the rhachises; involucres peltate, usually lacerate on their margins.

Scales on the lower part of the stipe numerous, lanceolate-linear, secund, ascending, 
somewhat rigid, dark chestnut, nearly black in the centre, their margins glistening 
white; tufts of hair-pointed scales on the rhizome. Young fronds usually entirely 
thickly covered beneath with lanceolate chestnut coloured scales, and generally with ` 
yellow powder, in which state it has been confused with Ch. rufa; but it has none of — 
the woolly hairs in which Ch. rufa always abounds. This is probably what Col. Beddome 
means when when he says (Ferns, Suppl. p. 7) that “ he has lately obtained De 
traces of it are sometimes permanent —1 haye collected large quantities of this Ka as P 
has H. C. Levinge. Bee
