Morpho-anatomical and palynological studies on Glaucosciadium cordifolium (Apiaceae) from Turkey

Background and Aims: The aim of the present study was to determine the morphological, micromorphological, anatomical and palynological characteristics of Glaucosciadium cordifolium (Boiss.) B.L. Burtt & P.H. Davis Methods: Measurements were performed on approximately 30 different samples for morphological study. The fruit micromorphologies and pollen properties were examined using scanning electron microscopy. For anatomical studies, all sections prepared from stem, leaf and fruit were taken by hand. Results: Cross-sections of stem, leaf and fruit are examined and a detailed anatomical description is presented and supported by photographs. It is a glaucous perennial herb with a height of 34-180 cm which has an acrid smell when bruised. The fruit is a dry schizocarp, glabrous and oblong-elliptic. The mericarp is elliptic in the transverse section which is winged in the lateral. The fruit surface ornamentation of the genus is occasionally wavy and striped and the upper surface simple, short and scaly. The stomata is observed. Conclusion: In this study, morphological, anatomical and palynological properties of the Glaucosciadium cordifolium are described and illustrated for the first time. In addition, the palynological results confirmed the stenopalynous characteristic of the family Apiaceae, and revealed that the pollen grains of the genus are perprolate in shape.

Automated summary

This study provides a detailed description of the morphological, anatomical, and palynological characteristics of Glaucosciadium cordifolium, including its plant properties and fruit morphology. Through anatomical and scanning electron microscope observations, the fine structure of the plant is revealed.
