A Study of the Anatomy and Pollen Morphology of Two Economically Important Species of Stachys L. (Lamiaceae) in Turkey

Abstract

In this study, the detailed anatomical properties and morphological structure of the pollen of the Turkish taxa Stachys annua
(L). L. subsp. annua var. annua and Stachys byzantina C. Koch were observed by light microscope for the first time. The plants
have a compact root anatomy with a full xylem component in pith. Lamiaceae demonstrated a typical four corners in the stem,
and under a single sequenced epidermis is to be found 3-4 sequenced layers of the collenchyma cell, while at the innermost we
can see a compact parenchyma. In the leaf mesophyll, the palisade and spongy parenchyma cells are of a similar shape. The leaf
is amphistomatic. The plant has an amaryllis, a mesomorphic, and an anisocytic type stomata. The results of the light microscope
investigation revealed the suboblatae-subprolatae and tricolpatae in the pollen of these two Stachys taxa. Upon close investigation
of the exine, it was also determined Stachys annua subsp. annua var. annua and Stachys byzantina are tectatae-granulatae.
