Table 3.

Contribution to observed variation in quantitative measurements. Results from a hierarchical ANOVA using the data from the two parental species R. delavayi and R. irroratum; intermediates were not included. Variation in quantitative measurements explained by differences between measurements: within the same individual, between individuals of the same species and between species. Negative values for the level ‘between species’ indicate that this level is not present in the data, which results in an artefact. Characters with large contribution from differences between species are marked with **, and the ones for which the level seems to be somehow meaningful are marked with *.
