Anatomical And Glandular Trichome Characteristics of Scutellaria salviifolıa (Lamiaceae) Endemic to Turkey

Abstract

The anatomy and glandular trichome morphology of endemic Scutellaria salviifolia Bentham (Lamiaceae) were examined to comprehend the important characteristics for systematic purposes. Some anatomical characters for example often 2 rarely 9-12 rowed pith rays in roots, the quadrangular stem and sclerenchymatous cells groups on the corners of stem, caryophyllaceous stoma and izobilateral leaf, one small subsidiary bundle on the corners and one big vascular bundle in petiole provide important information of taxonomical significance. Four different glandular trichome types were determined on S. salviifolia. The glandular trichome types were peltate (type I), type IIA, type IIB and type IIC capitate glandular. Peltate, type IIA and type IIB capitate glandular trichomes were seen nearly all organs of S. salviifolia, but type IIC capitate glandular trichomes were observed on only calyx. Type IIC capitate glandular trichomes are of very special type, which can be the significant taxonomic character of plant.
