Studies on the trichomes of some eupatorium species

, : Studies on the trichomes of some eupatorium species. Journal of Economic & Taxonomic Botany 5(5): 1175-1180

Trichomes were studied in 7 spp. of Eupatorium [E. reevesii Wall., E. cannabinum L., E. odoratum L., E. japonicum Thunb., E. riparium Regel, E. ligustrinum DC. and E. adenophorum Sprengel]. Both glandular and non-glandular types were observed. Among non-glandular hairs, achenial hairs were observed only on the floral parts. Their presence on the vegetative parts have not been reported till now. The structure and organographic distribution of trichomes could be utilized for taxonomic purposes at generic and specific level. Distinction between all species of Eupatorium studied can be made on the basis of trichome characters. Based on the trichome types a key is prepared for the identification of presently studied species.

At their altitudinal limits at 950 m elevation, Eupatorium adenophorum was more susceptible to density-dependent mortality but plasticity of individual organs including reproductive growth was more adversely affected in Eupatorium odoratum. In mix...
