Abstract
Leaf epidermal patterns in 18 species belonging to the genusPennisetum Rich., were described. The variation in the leaf epidermal characters was utilized for the identification of species. Macro hairs were recorded only inPennisetum americanum, Pennisetum clandestinum, Pennisetum polystachyon, Pennisetum pedicellatum, Pennisetum villosum, Pennisetum cenchroides, Pennisetum purpureum × typhoides (hybrid) andPennisetum orientale. Short cells between the veins were paired, solitary or more than two celled. Prickle hairs were absent only inPennisetum polystachyon. Hooks were absent only inPennisetum hohenackeri andPennisetum squammulatum. Stomata with triangular subsidiary cells occur in all the species. Silica bodies are of various types. A dichotomous key was prepared based on epidermal characters for the identification of the different species studied.
