Table 2 in A monograph of the genus Polylepis (Rosaceae)

Table 2. Overview of the available data on genome sizes, chromosome numbers and guard cell sizes in species of Polylepis. Where possible, literature records were assigned to this taxonomy, but a few data points (especially from the hybrid zone at Mojanda, Ecuador) had to be excluded because they could not be unambiguously assigned to a species. Depending on data source, we report the mean ± standard deviation, only the mean or a range. Data sources: 1. Kessler (1995b); 2. Quijia Lamiña et al. (2010); 3. Montalvo (2013); 4. Zurita et al. (2013); 5. Segovia-Salcedo and Quijia-Lamiña 2014; 6. Segovia-Salcedo (2014); 7. Kessler et al. (2014); 8. Caiza et al. (2018); 9. Boza et al. (2020). Abbreviations: Ar = Argentina, Ec = Ecuador, cult. = cultivated (in botanical garden), ind. = individuals, pl = planted.
