Lindernia crustacea / Urikusa ウリクサ

Lindernia crustacea is an annual plant that typically occurs in fields, vacant lots, or the corners of yards. Stems branch well to spread on the ground. Leaves in an alternate arrangement are 0.7-2cm long, 0.6-1.3cm wide, oval, or broad oval, with coarse serrations on the margins. In sunny places, stems or leaves tinge purple. The axils on the upper parts bear single, light purple flowers. Corollas are lip-shaped, about 8mm long; stamens are four in number, and two have stick projections on their bases attaching beneath the lower lips. Calyxes, 5-ridged, are shallowly cleft in five. The fruit (capsule), oblong-shaped, is enveloped by calyxes. Bloom time: August-October.
