Notes

The species included in the key were compiled from four botany manuals commonly used in southern California for the identification of plant species1 and from field notes. A shrub species was included if it was not restricted to desert habitats and if Los Angeles County was named or implied in the description of the range of the species. Vegetative characteristics used in the preparation of the key were secured from field study and from the four manuals referred to above. Manuals do not give a detailed vegetative description of a species, and occasionally notations on the less common variations of leaf form, leaf margins, and other vegetative characteristics are omitted. Thus the generalized notations given in botany manuals are inadequate for use in the preparation of a vegetative key. The botanist has no real purpose for giving exhaustive vegetative descriptions; his purpose is to provide a means of identification by floral analysis. Vegetative characteristics noted on flowering species in the field were used to correct and tci supplement data given in the manuals.
