Title: Anatomical, palynological and epidermis studies of genus Euphorbia species
Abstract: This study was conducted to evaluate anatomical comparison between six species of Euphorbia were investigated. Anatomically it has been shown that the shape of stem, midrib, lamina and margin were different. There were druses and tannins in lamina of Euphorbia microsphaera and absent in another species. The trichomes in stems were unicellular non-glandular and glandular in Euphorbia petiolate, Euphorbia phymutospering and Euphorbia peplus, while unicellular glandular in Euphorbia microsphaera and Euphorbia helioscopia, and unicellular non-glandular as in Euphorbia macroclada. In the leaf the trichomes were non-glandular and glandular unicellular in Euphorbia petiolate, while glandular unicellular in Euphorbia phymutosperin, Euphorbia microsphaeraand Euphorbia helioscopia. Secretory canal was presence in all species. The anticlinal surfaces of epidermis straight or wavy, the stomata were anisocytic, anomocytic, paracytic and hemi-paracytic with presence contiguous stomata. The pollen grains were different in size and shape such as spherical, oblate-prolate, sub-oblate and prolate spheroidal; the sculpture was foveolate or reticulate.
