Abstract


In the paper, glandular trichome micromorphology of Teucrium orientale L. var. orientale was studied to provide more information for systematic works. T. orientale var. orientale is a medicinal plant. It is named “Kirveotu” in Turkey. Stem, leaf, calyx and corolla samples of T. orientale var. orientale were fixed in 70% ethyl alcohol to determine glandular trichomes types and glandular trichome distribution. T. orientale var. orientale had peltate (Type I) and capitate glandular trichomes (Type II). Peltate ones composed four head cells and were observed both vegetative and reproductive organs.Three types of capitate glandular ones had determined in the study. These were subtype IIA, subtype IIB and subtype IIC capitate glandular trichomes. Subtype IIA and subtype IIB were seen on both vegetative and reproductive organs, whereas subtype IIC was observed on only reproductive ones.
