Description

Diplacus nanus is a hairy annual herb growing at ground level or erect to 10 centimeters tall. The oppositely arranged purple-green leaves are oval or oblong and up to 2.5 centimeters long.

The tubular, wide-faced flower is usually magenta or purple with two yellow stripes in the mouth, but is occasionally all yellow. The flower is up to 2 cm long.
