Anatomical studies of leaf, stem, rhizome and pollens in Polygonatum (Asparagaceae) in Iran

Polygonatum belongs to Asparagaceae with having 60 species in worldwide that distribution in temperate of north hemispherical, especially in the Hymalaia, Japan, China, India, Korea, Afghanistan, Nepal, Pakistan, Iran, Syria, east-north of America and Europea that 3 occur in Iran. These species as such as: P. orientale, P. sewerzowii and P. glaberrinum. Polygonatum growth in the forests of Prolific and dense. These researches have been in the next of taxonomy studies as such as anatomical leaf, stem and rhizome and pollen micromorphology. The aim of this studies is survey identification between of species in the base of anatomical features of leaf, stem and rhizome and micrograph electron microscopy features pollen. the result indicate that feature of anatomy and palynology can be using for identification between species.
