Abstract

Pollen grains of seven species of the genus Campylotropis in Thailand were described and illustrated based on investigations by light microscopy (LM) and scanning electron microscopy (SEM). The pollen grains were found to be generally monad, isopolar, radially symmetric and prolate. Apertures were tricolporate with lalongate endoapertures. The margo along colpi was psilate, perforate or absent. Exine ornamentation was microreticulate or microreticulate to reticulate, with lumina size diminishing toward the aperture. Types of lumina were a vertical or declined margin. The results of this study illustrated characteristics that can assist investigation of some Campylotropis pollen grains at interspecific level: presence and type of margo, type of ornamentation and type of lumina margin. Palynological studies of Campylotropis bonii, C. harmsii and C. pinetorum are firstly reported here. In addition, palynological description of each species, photographs and identification key to species based on palynological evidence are also presented.
