This fern has the remarkable coat of absolutely black scales, completely 
clothing the apex of rhizome and base of stipe, characteristic of Athyrium 
meyenianum; in other respects it is much like A. Blumei, except in the 
details noted above.

A very distinct little fern of the Alpine summit. Mixed with No. 10649 
is one small plant which may be a Scleroglossum.

Sarawak, Mount Bongo, Brooks, February, 1908. 
So far as one might judge from diagnoses, this might be Polypodium 
lasiosorum Hooker; but study of Javan material satisfies me, as it has 
Blume, Beddome, and others, that the latter is only a small form of P. 
hirtellum Bl., with forks of the veins subequal. I have never seen P. hir- 
tellum except in Javan material. Beddome, Ferns of British India 172, 212, 
twice figures a Ceylon fern, probably similar in venation to that described 
here, although he describes the veins on page 172 as simple; we have this
