ABSTRACT

Pollen morphology of 24 species of  Vatica L. had been investigated using light and scanning electron microscopes. Vatica is a stenopalynous genus, the pollens are radially symmetrical, isopolar, subprolate to suboblate sometimes prolate rarely oblate, all tricolpate. Exine ornamentation varies from thin to medium reticulate. On the basis of pollen shape two groups of Vatica have been recognized. Within the genus pollen diversity is valuable for identification and delimiting species.

Keywords: Dipterocarpaceae; Peninsular Malaysia; pollen; Vatica

ABSTRAK

Morfologi debunga 24 spesies Vatica L. telah dikaji dengan menggunakan mikroskop cahaya dan imbasan elektron. Vatica ialah genus stenodebunga, debunga adalah bersimetri jejari, isokutub, subprolat hingga suboblat, kadang-kadang prolat jarang oblat, semua trikolpat. Hiasan eksin bervariasi daripada retikulat nipis hingga sederhana. Bentuk debunga dua kumpulan Vatica telah dikenal pasti. Adalah penting dalam genus kepelbagaian debunga untuk pengecaman dan penghadan sempadan spesies.

Kata kunci: Debunga; Dipterocarpaceae; Semenanjung Malaysia; Vatica
