PLANTS MIAO Shen-Yu WANG Hou-Lin Abstract Dayao Mountain in Guangdong Province,is located
at the middle sub-tropical region and 113o13'02"E by lat.25o11'18"N.Recent
investigation on fhora of vascular plant shows that it has a total species
(including varieties)of 1411belonging to 194families and 701genera.The
fern of 132specieshas a has a high rate in the flora and indicates the
flore is an old one..The characteristic families of flora and vegetation
are Fagaceae ,Theaceae,Lauraceae,Magnoliaceae,Hamamelidaceae,Moraceae,Myrisnaceae,Symplocaceae,etc.,all
of which are the basic elements of Cathayasian flora.Phytogeographically,the
pan-tropical genera are a common , meanwhile the tropical elements and
temperate elements also appear in this area,but most of them include only
a few species.It's possible to believe that this area is the north border
of the tropical plant and the south border of the temperate plant.The
composition,which is complex,shows the nature of old origin and species
diversity of plant are typical in the flora of Dayao Mountain.
