Abstract: A detailed study of trichome morphology was carried out in floral parts of eight members of Ericaceae viz. Enkianthus deflexus Schneider, Gaultheria hookeri Clarke, Lyonia villosa Hand- Mazz, Pieris formosa Don, Agapetes serpens Sleumer, Vaccinium retusum Hook and Vaccinium vacciniaceum Slemer. The present investigation dealt with the structure, development and distribution of tricromes on the floral parts. They are of different sizes and shape. Glandular head and a stalk is only observed in Agapetes serpens. In rest of the members they are non- glandular type which are unicellular papillate hook type, thorn type filamentous type, filamentous brached type and uniseriate 2 called and 5-6 celled trichromes. They serve as important parameter for taxonomic purpose.
