Abstract:
The present study was carried out with aim to study the microscopic characters of Coleus forskholii (Linn.). Various samples of this plant were collected from different phyto-geographical regions (C-1; Chamba, Uttarakhand, C-2; Dhanauti, Uttarakhand, C-3; Agriculture University campus, Jabalpur, M.P, C-4; Tamiya Forest, Madhya Pradesh, C-5; Bilaspur, Chhattisgarh) of country. Most of the samples showed similarities in macroscopic characters, slight variations in microscopic characteristics, but in quantitative microscopy some significant differences were observed. Microscopic evaluation clearly revealed that various diagnostic features like multicellular trichomes, anomocytic stomata were observed. Quantitative microscopical characters like stomatal number, stomatal index and trichome were observed. Here, this study indicated information of taxonomic significance. Leaf trichome formation is significant adaptive feature as it provides resistance against herbivory also.
