Morphological parameters which have taxonomic value (length of vegetative and floral parts, type of stamen, carpel) were determined. Anatomical study was done by simple transverse section of root stems (culms) and leaves (Johanson, 1940). To study the stomata, the paradermal cross sections were taken (Algan, 1981). For palynological study, the acetolysis technique of Erdtman (1971) was used. Chemicals were treated to remove resistant outer exine wall layer of pollen grain. Acetolysis stain is brownish in colour and acetolysis mixture was prepared in a measuring cylinder by slowly adding concentrated H2SO4 and acetic anhydride in 1:9 ratio. Glycerine gelly, 50 gm gelatin, 150 ml glycerol, 175 ml DH2O was mixed thoroughly and boiled in water bath for 1 to 2 h and 7 gm phenolic crystals were added to the mixture and mix thoroughly until warm and melted. The glycerine jelly was then poured on a Petri dish making a thin uniform layer of 0.5 cm thick. It was cooled
and preserved in a refrigerator.
