Interspecific Hybrides in the Genus Mentha

III. Mentha arvensis Linn. × M. spicata Linn

Abstract

F₁ hybrid between M. arvensis Linn. subsp. haplocalyx Briq. var. piperascens Holmes and M. spicata Linn. was produced. The hybrid is intermediate in morphological characters between the two parents and is completely sterile. The detailed cytology of the hybrid and the parents is described. The genome present in M. spicata is not homologous with any of the genomes present in M. arvensis subsp. haplocalyx var. piperascens.
