Electrophoretic and morphological comparisons in ten rain forest species of Shorea (Dipterocarpaceae)

Differences identified by electrophoretic separation of enzymes and other proteins are providing increasing informative for the study of evolutionary affinities within a genus. Zymogran compared with a scheme of putative affinities derived from a standard taxonomic classi based on consciously weighted morphological characters, as well as with indices of similarity on an array of morphological criteria relating to twigs, stipules, leaves, inflorescences and structure for 10 species of Shorea from southeast Malaysia. Shorea ovalis is placed in a separate of the genus from the other nine species; S. leprosula, S. parviflia and S. curtisii are related other on Rp data and a high degree of similarity is shown between these three spec S. dasyphylla.
