POLYPODIUM ITHYCARPUM sp. nov. 
Species gregis P. nigrescentis Bl. ; stipite 25 cm alto vel altiore ; 
fronde spectabile ultra 50 cm alta, late ovata, ad alam 5 ad 10 
mm latam pinnatifida; segmentis ultra 35 cm longis, 3 ad 5 cm 
latis, integris, glabris, membranaceis, angulo 45° distantibus, 
costa valida, plerumque ad basin deflexa ; venatione inconspicua ; 
soris utroque latere costam prope uniseriatis, inter se remotis, 
superne 1 mm elevatis, truncatis, usque ad 3 mm latis. 
Mount Kinabalu, Kiau, Topping 1578 (type), a small frond; Lobang, 
Topping 1778, a fragment of a large frond. 
On the specimens collected, the tips of every segment except one stunted 
one are broken off in collection or drying; the longest fragment is 35 cm 
long. In spite of the great size, and the thinness, the venation is no more 
conspicuous than that of P. punctatum (L.) Sw. The plant is further dis- 
ting-uished from P. nigrescens and P. longissimum (which are not easily 
distinguished in Borneo) by the even more prominent sori, the distance 
between them, and their remoteness from the margin.
