MORPHO-ANATOMICAL AND PALYNOLOGICAL STUDIES ON ENDEMIC CRENOSCIADIUM SIIFOLIUM BOISS. & HELDR. FROM TURKEY

Abstract

The genus Crenosciadium (Apiaceae) is represented by C. siifolium which is a monotypic endemic species, in the Flora ofTurkey. In the current study, morphological, anatomical and palynological features of C. siifolium are described in detail.Expanded descriptions and images of C. siifolium are given. Cross-sections of stem, leaf and fruit are examined and a detailedanatomical description is presented and supported by photographs. Mericarps are almost pentagonal in transverse section. Eachmericarp has 3-5 vittae on the valleculae and 6-8 vittae on the commissural. The pollen morphology of Crenosciadium isstudied by SEM. The palynological results confirmed the stenopalynous characteristic of the family Apiaceae, and revealedthat the pollen grains of the genus is perprolate shaped. Also fruit surface ornamentation of genus was rugulate-striate at equator and irregular striate at poles.
