Abstract


The Malvaceae is a large family of about 243 genera and 4225 species with medicinal and gardening importance. Palynological observations were carried out of 9 species collected from different localities of Purba Medinipur District during the period of February 2016 to December 2017. The present study reveals the pollen morphological characteristics, especially pollen shape classes like Oblate (1 species), Oblate-spheroidal (4 species), Sub-prolate (1 species) and Per-oblate (3 species) with diameter ranges between 35 µm (Urena lobata L.) to 115 µm (Malvaviscus arboreus Cav.). Pollen morphology is one of the most significant tool for the taxonomic study as well as systematics of plant taxa.
