Morphology of four species of Panicum, viz., P. antidotale, P. cymbiforme, P. decompositum and P. repens, is described. Some new morphological features of diagnostic value, which have not been reported earlier for these species, are described and illustrated. An assemblage of characters supposed to be primitive on the evolutionary scale are also described and their phylogenetic significance discussed.Full Text

On the basis of morphological characters, twenty indigenous and exotic collections of Panicum maximum Jacq. have been classified into five broad types. Morphology (including detailed floral morphology) of these types is described with illustrations. A considerable range of variation of taxonomic significance was met with in them in respect of several characters, both vegetative and floral. Some new characters of diagnostic value, which do not seem to have been reported upon for this species earlier, are described and a handy key to their identification given.
The seed progenies of these morphologically-distinct types were matromorphic and hence exhibited remarkable uniformity within themselves, indicating that the species is highly apomictic.
Some of these types exhibited characters which are considered to be relatively primitive; these characters are described and them phylogenetic significance indicated. Some evolutionary trends in this complex, heterogeneous taxon are discussed.

In an earlier publication, the authors (Jauhar and Joshi, 1966) morphologically described 20 collections of guinea grass (Panicum maximum) and grouped the material into five distinct types. The present paper records observations on foliar epidermal patterns in this material. The classification on the basis of dermotypic features studied in this paper conforms to the one based on morphological characters.Full Text
