Search for phytogeographic provinces in Sumatra

Abstract

The flora and vegetation of Sumatra resemble those of Malaya and Borneo. The validity of minor floristic subdivisions on Sumatra, representing 11 "sectors' on the island, was tested against forest and habitat information from vegetation mapping surveys, botanical specimens (mainly trees and lianas), and data taken from Flora Malesiana. Results of cluster analysis on flora distribution data point out main demarcation lines delineating 6 floristic sectors in the lowlands and 3 in the mountains. -from Author
