Abstract:The history and the present state of the classification of the Gramineae are briefly reviewed and a number of the different characteristics on which phylogenetic systems have been based are considered. The subjects of chromosome morphology and the application of idiograms and karyotypes to taxonomic studies are discussed. Avdulov's recently reported findings on the phylogeny of the grasses are summarized and compared with the results of other workers and those obtained in the present investigation.

“…These results confirmed the one previously reported by Hunter (1934) and Burton (1942). The results therefore showed that the uniform nature of chromosome numbers among the accessions with few cytotypes indicates the accessions belong to the two identified species, i.e.…”
