A quantitative study of a presumed hybrid swarm between Eucalyptus elaeophora and E. goniocalyx

Abstract

From measurements of fruit lengths, fruit weights, and lengths of fruiting umbels of trees from the species Eucalyptus elaeophora and E. goniocalyx and their presumed hybrid swarm, a formula is calculated for taxonomic classification using statistical discriminant theory. The rates of misclassification expected with the use of this formula are estimated. A simple geometrical model of the relationship of the species and the hybrid is investigated.
