THE FERNS OF BORNEO. 
more feet long with rather broad pale-brown scales at 
the base, otherwise naked, pale green when living, as_ is 
the whole frond. Frond 14 to 3 ft. long, 1 ft. broad in the 
middle, tripinnatifid, the lowest pinnee much the longest, 
up to 1 ft. but curved and ascending, so that in general 
outline the frond is elliptical rather than deltoid. Pin- 
nules 1 to 2 in. long falcate unequal-sided, acute, the 
lower side narrowed very gradually towards the base, 
and therefore much curved, entire, or crenate in the up- 
per part; the upper side narrowed suddenly, auricled, 
the base parallel with the rachis, beyond the auricle cut 
down about 2 into rounded finely serrate lobes. Veins 
pinnate in the lower part, simple in the upper. Sori fine 
reaching neither the midrib nor the edge. 
The whole fern is, when living, very flaccid and herbace- 
ous differing in this respect as well as in the form of 
of the whoie frond and of its several parts from the 
robust habit of A. maximum. I have named it provision- 
ally A. (Déipl.) Matangense.

oe) ) latifolium, Don. “ Variety ” Baker. This 1 have found 
only once, on Lingga Mountain in Sarawak. It has pinne 
14 ft. long, 5 in, wide at the base, pinnatifid at the apex, 
and below that 12-15 pairs of nearly opposite, stalked, 
deltcid-lanceolate pinnules, 2 in. 1. by # in. broad cut 
down nearly to the base into oblong, or slightly falcate 
segments, the lower ones crenate on the upper side. [ 
think it is probably a distinct species.
