Four endemic taxa of Onobrychis Mill. genus, some of them being classified in the endangered threat category, were investigated for root and stem anatomy. Onobrychis quadrijuga, O. argyrea subsp. argyrea, O. tournefortii and O. albiflora were studied in regard to specific anatomy for the first time within the hereby study. Anatomical characters as the size and shape of the periderm, cortex, cambium cells in root and epidermis, collenchyma, cortex, cambium and pith cells in stem belonging to these four Onobrychis taxa were determined in detail. Based on the roots and stems measurements and analysis, specific anatomical differences between species were revealed.

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.
