Abstract

The histochemical studies of the Delonix elata of the leaflet were investigated to certain the relevance of these characters in establishment of interspecific similarities and differences in these taxa. The results showed that leaflet is thin with fairly prominent lateral vein and midrib. The lamina is 110 mm thick, the lateral vein is 170mm thick and the midrib is 180 mm thick. Adaxial epidermis 10-20 mm thick. Adaxial groove, it is 1 mm thick. The outer ground tissue is narrow while the central ground tissue is wide and parenchymatous.
