Abstract:

The  genus  Calligonum  L. includes a total number of 35 species in the
world, of which 24 are in China. They are grouped into four sections, of which Sect. Ca-
lliphysae (Fisch. et Mey.) Borszcz. is the most primitive and Sect.  Medusae Sosk. et
Alexender. is the most progressive.
     The Calligonum L. is an ancient genus in the arid desert flora, and central Asia is
the place of its origin.  Some species migrated to the Middle Asia and Iran, developing
into a second center there. Also, some newly occurred species of the Middle Asia emi-
grated eastwards to central Asia, so the genus Calligonum L. in China comprises compo-
nents of both central Asia and the Middle Asia.
     The genus Calligonum L. is distributed in North Africa, south Europa and Asia,
and China is the eastmost part of the distribution range.  They grow in Nei Monggol,
Gansu, Qinghai and Xinjiang.  There are 12 species in the Zhuengar Basin, covering 50
percent of the total number of species in China, amd thus the genus is the most abundant
there.
