Abstract: 1. A detailed study of cytology of 36 varieties of Pennisetum typhoides L. has been carried out.2. These varieties representing far stretched parts of the globe exhibit remarkable differences in their size and gross morphology. The different varieties differ in the number of different type of chromosomes in regard to structure alterations and size differences. These factors are constant for the variety and may be used as its cytological label.3. Chromosome type No. 26 exists in all the varieties except in variety Nos. 4, 8 and 33 where it is presumed to have undergone certain structural modifications during the course of evolution of these varieties.4. By study of evolutionary trends on the basis of chromosome symmetry, size etc. it is inferred that only the eight types out of 36 studied are the old ones.
