Hybridization between South American Jarilla and North American diploid creosotebush (Larrea, Zygophyllaceae)

Different strains of the two diploid Larrea species L. divaricata (S. America) and L. tridentata (N. America), are compared morphologically, cytologically, and in their seed proteins. There are minor differences, also in chiasma frequencies. Experimental F1 hybrids have near-normal meiosis but are s...
