Abstract

Nonea Medik. species are represented worldwide by about

35 species and represented by 23 species in Turkey. Nonea

species are commonly known as Sormuk otu and some

species use as folk medicine; aerial parts prepared as porridge

are used for wound healing and internally for stomachache

in Turkey.

In this study stem and leaf anatomy of the endemic Nonea

dumanii Bilgili & Selvi species (Boraginaceae) was investigated.

In the cross section of stem, cortex has 2-3 layers collenchymatic

cells and multilayered parenchymatic cells. Epidermis contains

glandular and eglandular trichomes on stem and leaf. Xylem is

composed of sclerenchymatic cells and tracheary elements in

vascular bundles. The pith is composed of parenchymatical

cells.

Stomata are anomocytic and amphistomatic in leaves. The sizes

of stomata in abaxial surface are bigger than the sizes of stomata

in adaxial surface, also stomata index of abaxial surface is bigger

than in adaxial surface. Minor bundles are surrounded by one

layered parenchymatic sheat in leaf. Palisade tissue is existing

on both side of leaf (isobilateral). Spongy tissue
