Plants hermaphroditic or unisexual. Leaves usually green to bluish green, sometimes bright green, sometimes glaucous, thin but ± stout (slightly thicker than F. vesca), sometimes slightly leathery, not reticulately veined abaxially, terminal tooth of terminal leaflet usually shorter (often narrower) than adjacent teeth. Flowers bisexual or unisexual (plants dioecious, gynodioecious, or trioecious); hypanthium 9.5–27 mm diam.; petals 5, obovate to widely obovate, margins overlapping or distinct. Achenes usually deeply embedded, rarely in pits or ± superficial, yellowish green to reddish brown, 1.2–1.8 mm; bractlets clasping, spreading, or ± reflexed, sepals clasping; torus usually not easily separate from hypanthium.
Distribution
North America.
Discussion
Subspecies 4 (4 in the flora).
It seems inappropriate to the author to follow the proposal of K. E. Hokanson et al. (2006) to reclassify the subspecies of Fragaria virginiana to forms.
Selected References
None.
