[Overview]
An annual or biennial 10–60 cm tall, found in sunny places along roadsides and on vacant land.
The stem is erect, slender, and branches at the base.
Leaves are simple and alternate, linear, 5–25 mm long.
A raceme at the stem tip bears flowers that open in order from the bottom.
The flowers are lipped, about 1 cm across, pale purple with purple veins.
The upper lip is shallowly 2-lobed and the lower lip is 3-lobed.
There is a tubular, pointed spur.
It resembles Matsuba-unran, but can be distinguished by its larger flowers, the center of the lower lip not being white, and the purple veins over the whole flower.
