Discussion | Varieties 2 (1 in the flora). Authorship of Fragaria indica is sometimes ascribed to Jackson in Andrews, because it is likely that Jackson prepared the text that accompanied illustrations by Andrews (F. A. Stafleu and R. S. Cowan 1976–1988, vol. 1). Because this is not indicated in the work itself, authorship is here retained as Andrews. Variety microphylla T. T. Yu & T. C. Ku of Tibet has smaller, densely villous leaves. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Genera 14–22, species ca. 860 (14 genera, 189 species, including 1 hybrid, in the flora area). The base chromosome number for Potentilleae is mostly x = 7 (8 in Alchemilla and Aphanes; 14 in Comarum). Variation in the number of genera recognized in Potentilleae is due to differences in generic delimitation between D. Potter et al. (2007) and the authors of Potentilla and segregates here (see 9. Ivesia and 8. Potentilla for discussion). In the former, Duchesnea, Horkelia, Horkeliella, and Ivesia are included within Potentilla. Likewise, Aphanes is included within Alchemilla by Potter et al. while it is kept distinct here. Potentilla and its segregates and Fragaria are host to Phragmidium rusts, but not the other genera of the tribe. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
