Abstract
MORPHOLOGICALLY the grasses Lolium perenne and L. temulentum are markedly dissimilar and easily distinguished from one another. They differ also in habit and in their breeding system; the former is perennial and outbreeding, while the latter is an annual and inbreeding. Despite their divergencies in form and habit, the species can, however, be crossed, and hybrid plants are readily grown from seed produced when L. perenne is used as female parent. This was demonstrated by Jenkin1, who has described the hybrids in detail.
