✦ Synopsis

Fifty-four species of the Chenopodiaceae in Israel were examined for their anatomical features, δC values, habitat and phytogeographical distribution. 17 species have δC values between -20‰ and -30‰and non-Kranz anatomy (NK) and are therefore considered as C plants. 37 species have δC values between -10‰ and -18‰ and Kranz or C-Suaeda type anatomy and are therefore considered as C plants. Some C plants have leaf structure which seems to be intermediate between the Kranz and the C-Suaeda type of leaf anatomy.The segregation of the species into photosynthetic groups shows tribal and phytogeographical grouping. Most of the C Chenopods are either mesoruderal plants or coastal halophytes, with a distribution area which covers the Euro-Siberian as well as the Mediterranean phytogeographical regions. The C Chenopods are mainly desert or steppe xerohalophytes with a distribution area which includes the Saharo-Arabian and/or Irano-Turanian phytogeographical regions.
