ABSTRACT

The present study is aimed to examine the significance of trichome structure and their organographic distribution for taxonomic delimitation in the taxa of family sterculiaceae. Ten species belonging to 8 genera viz. Buettneriaherbacea, Erioleanahokkeriana, Helicteresisora, Melhaniahamiltoniana, Melhaniafuttyporensis, Melhaniatometa, Melochiacorchorifolia, Pterospermumacerifolium, Sterculiaurens, Waltheria indica were selected. Total 29 trichomes types recognized during present investigation. Out of which, 27 belong to non-glandular and to glandular once. Some type are common and found in most of the taxa viz. unicellular flagellate, uniseriate conical and stellate multi-radiate whereas unicellular papillose, unicellular cylindrical, bi-cellular filiform, bi-cellular aseptate flagellate, uniseriate conical, uniseriate hooked, uniseriate curved , uniseriate aseptate flagellate, peltate, glandular flagellate and uniseriate glandular capitate appeared quite significant to a particular species for taxonomic delimitation in Sterculiaceae.

Key words : Organographic distribution, Sterculiaceae, Taxonomic significance, Trichome.
