Mosla dianthera, an annual plant 20-60cm tall, occurs on mountain fringes or roadsides. Stems with a square cross-section have short, downwardly curved hairs on the ridges. Leaves are opposite, 2-4cm in length, oval to broadly oval, and somewhat thin, with coarse serrations along the margins. Branches end in 3-7cm-long spikes, each bearing light red-purple or white, lip-shaped flowers. The upper lip is cleft in three, and the lower lip becomes hollow. Bloom time: September-October
