Table 1 The position of sexual organs in 15 and seven dimorphic populations, respectively, of Narcissus assoanus and N. dubius. Mean values (mm) are given for stigma height, upper-stamen height and lower-stamen height. Sample sizes were 450 L- and 272 S-styled flowers for N. assoanus and 275 L- and 53 S-styled flowers for N. dubius. Sex-organ position was adjusted to account for differences in flower size and significant differences were assessed using ANOVA (see text for details). There are statistically significant differences between the style morphs in stigma height, upper stamen height, and lower stamen height in both species
