Systematic Foliar Morphology of Phyllanthoideae (Euphorbiaceae). II. Phenetic Analysis

open access: yesAnnals of the Missouri Botanical Garden, 1986
Cladistic analysis of 43 foliar characters was used to explore the phylogeny of genera in Phyllanthoideae and to test the systematic value of foliar morphology. Character polarities were assessed by outgroup analysis treating other subfamilies of Euphorbiaceae and primitive genera in Flacourtiaceae as outgroups.
