The Genus Lolium in Australia

Abstract

The genus Lolium is represented in Australia by the following five species: L. perenne, L. multiflorum, L. rigidum, L. loliaceum and L. temulentum. L. remotum is probably extinct in Australia as it has been found only associated with flax crops which are no longer grown locally. Natural and bred hybrids between the three outcrossing species are also found, viz. L. multiflorum × L. perenne (= L. × hybridum), L. multijlorum × L. rigidum and L, perenne × L. rigidum.

Earlier botanical treatments of the genus in Australia are reviewed. A diagnostic key, species descriptions and ecological notes are presented.
