A tree, from 60 to 80 feet high. In the typical form the upper part of the
cupule splits ofl m pieces, so that the glans may escape. In the var. apertu the
upper fourth of the glans is, from the earliest stages, uncovered by the cupule. In the
Sumatra specimens the acorns are more ovoid and less dejiressod than in those from
the Malayan Peninsula and Penang. The specics is a very distinct one.
