In this study a compare between the morphological and anatomical structure parts of the species Heliotropium supinum in Turkey specifically from Pamukkale were carried out to diagnostic the characters of it, this will helping to identify parts of this species. It had been found that the species reached to 0.55 m in height, the stem cylindrical, hairy and fleshy and the inflorescences are hilioscopia and the flower convolution in double rows also the cross section of stem appear that the shape of stem oval and the epidermis surface is wavy and covered by trichomes, cortex consists from 4-6 layered of collenchyma beneath the epidermis and 7-11 layered of parenchyma also can discrimination ten specialized schizogenous intercellular space in the cortex that store the active compounds, phloem element and xylem are noted and the pith at the center with abounded resin ducts.
The transverse sections of the leaves showed that the upper and lower epidermis is single layer irregular in shape with sinuous and thick walls covering by unicellular and uniseriate trichomes, follow the epidermis two palisade layers, under it three spongy layers, midrib of leaf consists of a single layer of epidermis covering by unicellular and uniseriate trichomes and collenchyma layer beneath the epidermis so the parenchyma tissues is full up the inside of midrib, vascular bundle open and collateral, crescent shaped, consists of xylem and phloem. The petiole of leaf drumstick or bone shape, the epidermal cells 4-5, wavy on the adaxial and abaxial side and covering by trichomes, stomata are on the adaxial and abaxial surface, anisocytic type. The scanning study of mature pollen grains of Heliotropium supinum showed that the pollen small size, prolate-spheroidal shape, monoporate and the exine sculpturing psilate.
