Abstract
In this paper, anatomical, palynological and seed micromorphological properties of an endemic plant Matthiola anchoniifolia Hub.-Mor. are recorded for the first time. A description and descriptive illustrations of the species are given based on the collected specimens for morphological study. Seed surface of M. anchoniifolia is examined by scanning electron microscope. The seed of M. anchoniifolia was compressed, brownish in colour and the cells of testa were nearly 60-80 μm in diameter and ranged from isodiametric, tetragonal or pentagonal. The anticlinal walls were straight or weakly curved while the outer periclinal walls were concave to flat with smooth surface. In anatomical study, cross sections of root, stem and stem leaf are examined. The root had secondary structure. Periderm consists of 5-8 layers of cells for phellem. Cortex consists of 9-12 layered parenchymatic tissue under the periderm. Secondary phloem ring-shaped, 6-9 layered and consists of companion cells and grouped sieve tubes. Stem had primary structure when analyzed. It is circular with a few irregular ribs in cross section. Cortex is 8-12 layered and parenchymatous. Stoma cells are present on both epidermis. Leaf is isobilateral. There are unicellular and ramified hairs on both surface. Palisade parenchyma cells are 1-2 layered and spongy parenchyma cells are 5-12 layered. M. anchoniifolia has tricolpate pollen type, prolate pollen shape and reticulate exine ornamentation.
Highlights
Brassicaceae has been represented by 365 genus and 3250 species in the world and it is indicated as a huge family (Simpson, 2006)
M. anchoniifolia has been distributed in Sivas province in Turkey (Cullen, 1965)
There is no report on the anatomy, palynology and seed micromorphology of M. anchoniifolia which is an endemic species in Turkey
Summary
Brassicaceae has been represented by 365 genus and 3250 species in the world and it is indicated as a huge family (Simpson, 2006). There is no report on the anatomy, palynology and seed micromorphology of M. anchoniifolia which is an endemic species in Turkey. Morphological, anatomical and palynological properties of M. anchoniifolia were given in detail for the first time. For measurements of polar axis, equatorial diameter, exine thickness and lumina size of pollen grains were used 100× objective of Olympus light microscope CX21.
