Discussion
Waldsteinia doniana is usually synonymized with W. parviflora; according to M. L. Fernald (1935) it is based on an aberrant cultivated form of W. fragarioides. Waldsteinia fragarioides and W. parviflora are often combined, then often distinguished as varieties. The flower size of W. fragarioides is very variable, and it seems that larger flowers are more usual in the north of the range. The best differentiator from W. parviflora is sepal length relative to petal length, and all specimens with adequate material seen by the author were distinguishable. Waldsteinia fragarioides is used as a mat-forming groundcover in ornamental horticulture.
