Based on the records of January 2000, there are 133 species of 74 genera in 11 tribes.  <br />The tribe Heliantheae is the largest, with 28% of the total number of the genera, followed by Astereae with <br />15%, Inuleae 12%, Senecioneae 10%, Anthemideae, Eupatorieae and Lactuceae 8%, the other tribes are represented by <br />4% or less. <br />The most diverse genus is Blumea with 14 species. Other genera are only represented by 10 species or less, usually <br />4, or 3, or 2, and mostly by 1 species only. <br />Thirty nine or about 53% are exotic genera and the native ones are less than half of the total number of the <br />genera. <br />In terms of indigenous and endemic species, Sumatera is richer than Java. There are 1 genus, 7 species and 2 <br />varieties of Asteraceae endemic to Sumatera. <br />A number of 43 important weed species were introduced from Tropical America, Africa, Asia and Europe. Among <br />these Chromolaena odorata and Mikania micrantha are reported as the most noxious ones.  <br />List of the genera and species recorded in Sumatera is provided in this paper. <br />Key words : Asteraceae/Sumatera/compositions/endemic species/distribution/weedy Asteraceae}, number={19}, journal={BIOTROPIA}, author={TJITROSOEDIRDJO, SRI SUDARMIYATI}, year={2011}, month={Nov.} }
