*Malva parviflora  Small-flowered Mallow
ANNUAL.  Leaves rounded, small, with three to five lobes, toothed edges, and prominent radiating veins.  The five sepals are united to form a shallow cup that completely contains the flowers and (later) the fruits.  Flowers white, petals may be tipped with light purple.  Fruits green to reddish, disc shaped, segmented.  M. neglecta (Cheeseweed) is similar but larger, with larger purple-striped flowers that exceed the sepals, and thicker, more obviously segmented fruits.  Both are exotic weeds on disturbed ground, and bloom throughout the summer.
FAMILY:  Malvaceae  (Mallow Family)
