Pollen morphology of the Sapotaceae from Thailand and its taxonomic implications.
The external pollen morphology of the family Sapotaceae in Thailand was examined using the acetolysis method to determine its taxonomic significance. Pollen of 39 specimens belonging to 32 species was investigated by means of light and scanning electron microscopy. Pollen grains are found to be monads, isopolar, colporate, lalongate, and...Kunasit, Pongsakorn ; Chantaranothai, Pranom
