Anatomical and pollen characters in the genus Epilobium L.(Onagraceae) from Northeast Anatolia

100%

Makbul S. , Turkmen Z. , Coskuncelebi K. , Beyazoglu O.

Acta Biologica Cracoviensia. Series Botanica

2008

tom 50

nr 1

Anatomical and palynological features of E. algidum Bieb., E. palustre L., E. ponticum Hausskn., E. confusum Hausskn., E. hirsutum L. and E. montanum L. collected from NE Anatolia were examined and evaluated by numerical analysis in order to determine the taxonomic value of the observed internal peculiarities. Features related to pollen shape and ornamentation, idioblast distribution, number of palisade parenchyma rows and the presence and distribution of sclerenchyma fibers were found to be important in separating the examined taxa. Principal component analysis showed that the anatomical characters are more important than the palynological ones in explaining the total variation among the examined taxa.

Morphology and anatomy of Scrophularia L. [Scrophulariaceae] taxa from NE Anatolia

100%

Makbul S. , Coskuncelebi K. , Turkmen Z. , Beyazoglu O.

Acta Biologica Cracoviensia. Series Botanica

2006

tom 48

nr 1

This study uses numerical methods to describe, illustrate and assess the taxonomic significance of morphological and anatomical features of Scrophularia ilwensis C. Koch, S. capillaris Boiss. & Ball., S. nodosa L., S. libanotica Boiss. var. pontica R. Mill, S. lucida L. and S. cinerascens Boiss. collected from NE Anatolia. Features related to peculiarities of the leaf, bracteole, alar pedicel and corolla were found to be important in separating the taxa morphologically, but principal component analysis of all characters showed some anatomical characters (mean number of stomata, diameter of vascular bundle and scleranchymatic sheath) to be more important than morphological ones in explaining the variation between the examined taxa.
