Table 1 ANOVAs for fruit set and seed numbers. Results of ANOVAs testing the contribution of several factors to seed production in pollination treatments carried out in 2015. Three stages were assessed: Fruit set (percentage of pollinations that resulted in fruit); Seed numbers per fruit; Seed number per flower. The following factors (with given levels) were included: Mother Species (anisodora, poissonii); Flower Type [of mother plant] (pin, thrum); Pollen Source (anisodora, poissonii); Cross Type (intra-morph, inter-morph). Significant results are highlighted in boldface. Nominator degrees of freedom (d. f.) = 1, denominator d. f. = 91
