Abstract:
The present paper describes the pollen morphology of Trigonobalanus doichan-
gensis (A. Camus) Forman of Fagaceae. Comparative study on pollen grains was carried out
by means of light microscope, scanning and transmission electron microscope.
The pollen grains of T. doichangensis are subspheroidal or suboblate but in polar view
they are subtriangular, and in equatorial view they are subcircular they are 27.3, 23.1-
29.4)×27.3(25.2-29.4) μm in size and 3-colporate goniotreme. The exine is 2-layered, 2.4-
4.2μm, thick in apocolpia. The sexine cosists of tectum, bacules and endonexine under TEM.
On the basis of pollen shape, type of aperture and exine structure the pollen grains of T.
doichangensis are distinguishable, from those of other genera in Fagaceae and it may belong to
a new type of Fagaceae.
