formation of the raspberry or blackberry and the strawberry: in
the former it is the carpels (ovaries) that swell around the
spongy receptacle into numerous little fruits (drupelets) united
into one berry, whereas it is the cushion-like receptacle itself
in the strawberry blossom that swells and reddens into fruit,
carrying with it the tiny yellow pistils to the surface.

The NORTHERN WILD STRAWBERRY (F. Canadensis), with clusters of
elongated, oblong little berries delightful to three senses,
comes over the Canadian border no farther south than the
Catskills. Nearly all strawberry plants show the useless but
charming eccentricity of bursting into bloom again in autumn, the
little white-petaled blossoms coming like unexpected flurries of
snow.

No one will confuse our common, fruiting species with the small,
yellow-flowered DRY or BARREN STRAWBERRY (Waldsteinia
fragarioides), more nearly related to the cinquefoils. Tufts of
its pretty trefoliate leaves, sent up from a creeping rootstock,
carpet the woods and hillsides from New England and along the
Alleghanies to Georgia, and westward a thousand miles or more.
Flowers in May and June.
