Abstract: A new and distinct hybrid of the genus Caesalpinia is provided. This hybrid has been named ‘Mnstamepa’ for a cultivar name and is trademarked as Sierra Sun™. The new variety is a product of a cross between Caesalpinia mexicana and Caesalpinia palmeri which occurred in the year 1996. The Genus/species designation for the plant is Caesalpinia mexicana×palmer.

Abstract: A new and distinct variety of the Baccharis plant named `Starn` is provided. The new variety was selected as a single plant from a block of hybrid seedlings. The new variety is a staminate plant that does not produce the white floss (pappus) and seed associated in large quantity with Baccharis plants. The new variety is heat tolerant, possesses drought resistance, exhibits procumbent growth habit and displays green foliage coloration. The characteristics of this new variety of plant make it particularly well-suited for growing as a ground cover in urban desert landscapes and regions with limited water supply.
