Abstract:
The systematic position of Paradombeya Stapf has been debated until now. The
studies on gross morphology, anatomy, palynology and cytology were undertaken to con-
firm the systematic position and affinities of this genus. The combination of features, e. g.,
umbel-like cyme, 2-celled anther, presence of staminodes, staminal tube, 15 stamens,
bifid cotyledons, wood anatomy, chromosome number of 2n=20, triporate, spiny and
spheroidal pollen grains, suggests that the genus be better placed in the tribe Dombeyeae
of the Sterculiaceae.
