Discussion

Subspecies 4 (2 in the flora).

Fragaria chiloensis was first described from cultivated plants that had been selected in Chile at least 400 years ago and brought to Europe in 1714. Subsequently, it was realized that wild-growing plants of this species exist in North America and South America. The typical subspecies is restricted to South America; subspp. lucida and pacifica are present in North America, and the latter in Hawaii as well.

The proposal by K. E. Hokanson et al. (2006) to classify subsp. lucida and subsp. pacifica as forms of one North American subspecies seems inappropriate.
