Eighteen types of trichomes have been described. Trichome complements of these taxa are variable in their structure and organographic distribution. On the basis of the latter, occurrence of biotypes in Vernonia albicans and varieties in Vernonia monosis and Vernonia peninsularis is visualised. Examination of pai- red affinity indexes of the trichome complements of lower leaf surface indicates that V. albicans and V. cinerea; V. monosis and V. shevaroyensis and V. indic and V. comorinen- sis are closely related.  aAsteraceae  ataxonomy  atrichomes  aVernonia  aPlanta  aTaxonomia  aPlant  tProceedings of the Indian Academy of Sciencegv.88 B, n.5, p.347-357, Sept. 1979.
