A PRELIMINARY STUDY OF THE FLORA AND DISTRIBUTION OF GENUS ACER IN ZHEJIANG PROVINCE

  • Received Date: 1989-08-25
  • The floristic feature and geographical distribution of Acer in Zhejiang is described in the present paper.It is concluded that Zhejiang,especially the northwest mountains,is a refugium and an active differentiating regioa of Acer.The species in the province are mainly the endemic elements of China,others are the temperate Asian and the East Asian (Sino-Japanese) elements.Most of them belong to Southwest,Central,and East Chinese Floristics,distributed in the mountainous belt of the evergreen-deciduous broad-leaf mixed forest,the deciduous broad-leaf and the needle-broad-leaf mixed forest,a few belong to South Chinese Floristics,distributed in the mountainous evergreen broad-leaf forest belt in southeast and south area of the province.Finally,the original region of the genus is discussed.It's considered that the tropical to south subtropical Indo-Chinese region is the primitive original centre of the genus,Hengduan Mountains to Central China is the strongly active differentiating region of most of the deciduous sections and series.

Abstract: The floristic feature and geographical distribution of Acer in Zhejiang is described in the present paper.It is concluded that Zhejiang,especially the northwest mountains,is a refugium and an active differentiating regioa of Acer.The species in the province are mainly the endemic elements of China,others are the temperate Asian and the East Asian (Sino-Japanese) elements.Most of them belong to Southwest,Central,and East Chinese Floristics,distributed in the mountainous belt of the evergreen-deciduous broad-leaf mixed forest,the deciduous broad-leaf and the needle-broad-leaf mixed forest,a few belong to South Chinese Floristics,distributed in the mountainous evergreen broad-leaf forest belt in southeast and south area of the province.Finally,the original region of the genus is discussed.It's considered that the tropical to south subtropical Indo-Chinese region is the primitive original centre of the genus,Hengduan Mountains to Central China is the strongly active differentiating region of most of the deciduous sections and series.
