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

description: 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.
