The morphology of microhairs on leaf surfaces of 44 Eragrostis species from India is studied using Scanning Electron Microscope (SEM) and the results are presented. Three distinct types of microhairs have been observed viz. chloridoid, panicoid and enneapogon (intermediate) and their features are tabulated.
