Abstract

Abstract

The study of Bibliography of Flora works is considered the most important source and which takes them interested in the field of plant biodiversity, and flora readings are a significant pillar of a scientific approach to the results of the new studies.

The registration of the species Euphorbia hyssopifolia L. for the first time in the flora of Syria, where previous studies did not refer to it.

The morphology and amatomy of leaves had studied.Characterized by the type studied leaf pattern Pseudo-Brochidodromous, which basically follows the pattern Pinnate-Camptodromous Type.

The  anatomical study of the bottom side of the leaves epiderm in the studied species clatified that it has3 types of stomata complex: Anisocytic, Anisotricytic, Anomocytic.

Results were compared with the morphological characteristics of the leaves nine species studied this criterion. It was obtained from kinship taxonomic tree cluster analysis conducted by taking advantage of 43 recipe for this analysis. The species Euphorbia hyssopifolia joined to the second node, which belonged to a cluster Prostrata-Form and showed the proportion of the similarity of 0.632 with E. prostrata.
