| Abstract: | Different strains of the two diploidLarrea speciesL. divaricata (S. America) andL. 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 semisterile. The parental species, therefore, biologically may be considered  allopatric semispecies . |
