Intraspecific and interspecific seed viability for crosses among M. caespitosa (C), M. minor (M), and M. tilingii (T). The first letter in each cross type indicates the maternal species. Least square means for cross types are given with ± SE. Least square means denoted by a different letter indicate significant differences among cross types (P < 0.05) determined by post hoc Tukey method. Sample sizes assessed for each cross type are listed above letters. (A) Proportion of fully developed seeds per fruit (visual assessment). (B) Proportion of seeds that germinated per fruit.
