The taxonomic position of the endemic Lolium canariense within the genus Lolium has been Investigated by starch gel electrophoresis of 7 isozyme loci. Preliminary results show that L. canariense is preferentially autogamous, with an outcrossing rate of 0.08-0.16. II displays an average gene diversity of intermediate value between that of the strict inbreeder L. persicum and those of the outbreeders L. perenne, L. multiflorum and L. rlgidum. The hierarchical clustering from Nei's genetic distance (Genelics 1978) suggests that L. canariense is clearly differentiated from the group of outbreeding species

The PLANTS database provides basic plant information to the United States Department of Agriculture (USDA), Natural Resources Conservation Service (NRCS), its clients, cooperators, and the general public via the World Wide Web (Fig. 1). The foundation of PLANTS is a taxonomic backbone (checklist) of the vascular and nonvascular plants of North America (north of Mexico) and United States territories in the Caribbean and Pacific regions. Attribute data are appended to this backbone pertaining to distribution, vegetative specifications, nativity, federal and state status, crop data, growth form, growth parameters, species abstracts, and images.
