Comparative anatomy and pollen morphology of jacquemontia choisy (convolvulaceae) in Thailand

Abstract

       The comparative anatomy of leaves and stems in 3 taxa of the genus Jacquemontia Choisy
(Convolvulaceae): J. paniculata (Burm.f.) Hallier f., J. pentantha (Jacq.) G. Don. and J. aff. paniculata (Burm.f.)
Hallier f. were investigated by leaf epidermal peeling and blades, margins, midribs, petioles and stems cross
section using paraffi n method. The results showed that some anatomical characters that could be used for species
identifi cation are type of trichomes, type of secretion on epidermal cells, shape of epidermal cells, presence of
fi bers and parenchyma surround vascular bundles in stems, secretion on mesophyll and number of vessel cells The comparative anatomy of leaves and stems in 3 taxa of the genus Jacquemontia Choisy
