Typology and taxonomic value of foliar sclereids in the Proteaceae 1.Isopogon R. Br.

  • T Ananda Rao
  • Silpi Das


The present work has revealed that 32 out of 38 taxa ofIsopogon possess variously shaped sclereids of diffuse pattern. Some species have grotesquely mis-shapen sclereids with thick wall and blunt arms. They are designated as gnarlyform sclereids. Further, the taxonomic problems alluded to by Bentham are discussed in relation to the types of foliar sclereids.
