ABSTRACT
Palestine was subject to classification study through the period from February to May 2017. This area has a characteristic of flora and biodiversity and belongs to dry, arid, semi-arid, sub-humid and humid climates, and locates in Mediterranean region. We took 400 samples of different plant species from Hebron (Idna, Althahreiyeh, Yatta villages and Hebron city); Jenin (Jenin city, Al-Yamon, Maysalon and Yabod); Jericho (Wadi Al-Qalt, Ain or Tal Sultan and Al-Nwehmeh) and Ramallah (Safa, Turmus Aya and Qibia). The absence of classification studies on the areas led us to run a statistical treatment on the 400 sampled flora of Palestine. Moreover, the classification was made following Braun-Blanquet in 1979; we transformed the Braun-Blanquet species abundance-dominance values into those of Van der Maarel in 1979. In the statistical treatment we obtained more than 53 plant species (Endemic rare) as Paronychia palaestina Eig , Trifolium palaestinum Boiss., Trifolium philistaeum Zohary, Suaedaphilistaeum Zoharyand, and others, representing forests, copses, herbaceous and high shrublands influenced by climate (climatophilous), and edaphohygrophilic, and bioclimate factors as ombrotype and thermotype. However, according to study area we indicated that the flora endemic rare has 53 species, which of them 13% belong to Compositae family, 7.54% Poaceae, Liliaceae & Papilionaceae families, and 5.66% Iridaceae family.
