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.

Polypodium hirtellum Brooks in Sarawak Mus. Journ. 1 (1912) 49, non 
Blume. 
Grammitis, rhizomate suberecto, paleis pallide brunneis ovatis 
obtusis vel acutis vestito; stipitibus confertis, haud articulatis, 
filiformibus, 0.5 ad 1 em longis, pilis vinicoloribus 1 ad 2 mm 
longis ornatis ; fronde 4 ad 7 cm alta, plerumque ca. 3 mm, rarius 
usque ad 5 mm lata, obtusa vel subacuta, deorsum sensim an- 
gustata, integra, subcoriacea, ubique setosa, setis usque ad 3 
mm longis, rubidis; venis sterilibus plerisque simplicibus, fertil- 
ibus prope costam furcatis, soro orbiculare ramum superiorem 
brevissimum insidenti et complente, receptaculo subelongato. 
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
