Floral Micromorphological and palynological studies of medicinally
important Plectranthus scutellarioides (L.) R. Br (Lamiaceae) from Assam
(Udalguri) using light and scanning electron microscopy.
Abstract
The palynology and distribution of the trichomes, on the aerial parts
and anatomy of Plectranthus scutellarioides from Udalguri district of
Assam were studied in order to understand the significance of these
features in systematics. The present work on Plectranthus
scutellarioides thus provides an empirical basis for the identification
of the species. Micromorphological features such as epidermal cell,
stomata and trichomes were also studied under both light microscope and
scanning electron microscope. The main types of trichomes - peltate,
glandular and non-glandular were observed in leaves. Different features
of pollen were observed and recorded. Photographs and Micrographs were
also provided. All the observations were done under Light microscope and
Scanning Electron Microscopy (SEM). The research provides the first
detailed descriptions of floral micromorphological and palynological
characteristics for Plectranthus scutellarioides, contributing to the
empirical identification of the species. The findings offer valuable
insights into the structure, size, and shape of stomata, as well as
trichome diversity and pollen characteristics
