== Uses ==
''C. teysmannii'' is a source of HIV reverse transcriptase inhibitors. The timber is used as bintangor, e.g. in construction.
== Observations ==
*Inflorescences axillary, usually unbranched, 3-11-flowered; flowers with 4-8 tepals.
*Fruit spherical to ellipsoid, 17-37 mm long, with fairly thick, compact and hard outer layer, greenish.
Two varieties occur throughout the range of the species: var. ''teysmannii'' (synonym: ''C. inophylloide'' King var. ''singapurense'' M.R. Henderson & Wyatt-Smith) growing in peat swamps, mixed dipterocarp forest, kerangas forest and on ridges in lower montane forest up to 1200 m altitude, and var. ''inophylloide'' (King) P.F. Stevens (synonym: ''C. inophylloide'' King) usually growing in well-drained lowland to lower montane mixed dipterocarp forest up to 1400 m altitude. The wood is rather heavy and hard. The bark often resembles mengkulang (''Heritiera'' spp.).
