Trichomes of fifteen species of Vernonia occurring in South India have been studied to evaluate their interrelationships. 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 paired affinity indexes of the trichome complements of lower leaf surfaces indicates that V. albicans and V. cinerea;V. monosis and V. shevaroyensis and V. indica and V. comorinensis are closely related. © 1979 Indian Academy of Sciences.
