THE FERNS OF BORNEO. 
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 
h e, 
and therefore much curved, entire, or crenate in the p- 
rt; the upper side narrowed suddenly, auricled, 
the base parallel with the rachis, beyond the auricle cut 
“down about 4 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 іп the form of 
of the whole frond and of its several parts from t 
robust habit of A. maximum. I have named it provision-

А. (Dipl.) latifolium, Don. * Variety " Baker. This] have found 
only once, on Lingga Mountain in Sarawak, It has pinnæ 
1} ft. long, 5 in. wide at the base, pinnatifid at the apex, 
and below that 12-15 pairs of nearly opposite, stalked, 
deltoid-lanceolate pinnules, 2 in. 1 by 3 in. broad cut 
down nearly to the base into oblong,or slightly falcate 
segments, the lower ones crenate on the upper side. I 
think it is probably a distinct species.
