Pennisetum pedicellatumTrin. has four wild biotypes. The paper deals with the cytomorphological aspect of four such types. Based on morphological characters they have been designated as Types-A, B, C and D, respectively. These types not only differ from each other in minor morphological details but also in their chromosome number (2n=54, 48, 36 and 54, respectively) and behavior giving rise to different races. The taxonomic significance of these races has been discussed. Since the species is a well established apomict and irregular meiosis is not a barrier to seed formation, it has been inferred that the different races are successfully maintained in a polyploid complex.
