A PRELIMINARY STUDY OIN THE FLORISTIC ELEMENTS OF THE COMMUNITY OF FORMANODENDRON DOICHANGENSIS

According to the result of wild survey on the FOrmanodendron doichangensis-commu-nity, the floristic elements of the communitv has been analysed.The Tropical Subtropical floristic elements are of a great deal(90.25 % of the total species),amcog them the Indo-Malaysian floristic elements are in the frist place(41.46%),the floristic elements of the bor-der land in Yuaana and other countries(Burma,Laos,Thailand and Vietnam)are in the second place(292% in total),the floristic elements relating to TropicaI Africa are few, but there are no the floristic elements relating to Tropical Australia or Tropical America. Based on the floristic analysis of the community,it is strong to support the view suggested by Kevin C. Nixon William L. Crepet:Formanodendron is a distinct genus and F.dOichangensis was originated from the ancestor of Trlkonobalanus verticillata in early Tertiary.
