Abstract

Techniques of systematic serology have been used to analyse protein similarities among taxa of the genus Viburnum. Nephelometric and double diffusion analyses indicate that serological correspondence can be correlated with the sections of the genus derived from analyses of gross morphological characters. Each section of the genus reacted as a serological unit, with representatives of the most primitive section showing least serological correspondence with those of the most advanced section. A wide range of serological reactivity was observed among the species examined suggesting the possibility of raising the sections to a taxonomic level above section. However, all taxa were included in a distinct serological group indicating that Viburnum is a distinct taxon.
