Abstract:
Information about trichomes diversity and distribution of the family Caryophyllaceae is rare and the present work is intended to fill this knowledge lacuna. In the present work 62 taxa belonging to 19 genera were studied. For the analysis of trichomes diversity and vestiture type, dried plant specimens were rehydrated with water. The final illustrations of trichomes were made by using camera lucida. Six types of trichomes viz., Unicellular eglandular, Unicellular glandular, Multicellular uniseriate glandular, Multicellular uniseriate eglandular, Multicellular eglandular bifurcate and Multicellular multiseriate eglandular trichomes reported in the studied taxa. Diversity of trichome and their distribution does not play any significant role in the taxonomic delimitation either generic or tribal level of the family Caryophyllaceae. Although, few closely allied species can be distinguished from each other either on the basis of the presence of trichomes or vestiture patterns.
