Abstract
Trichomes of twenty two taxa of the genus Solanum, Withania, Petunia, Capsicum, Atropa, Lycopersicon, Cestrum, Hyoscyamus, Datura, Physalis and Nicotiana were examined by using light microscope and photomicroscope. The indumentums shows considerable variations among different species, and therefore, useable characters in de-limitation of species. The study revealed the characters of anatomic interest of leaf and stem epidermal features that have not been previously reported before and has been conducted first time. Size, shape and types of trichomes were measured with considerable variability and the presence of glandular and non-glandular trichomes were observed. Distribution of foliar trichomes emerged as a supportive taxonomic and anatomic tool, which are present in the species mostly are unicellular, bicellular and non-glandular, glandular with bulbous base.
