[Overview]
An annual 40–80 cm tall, growing in moist places in the mountains.
The whole plant is hairless.
The leaves are simple and alternate, ovate to oblong, 4–8 cm long and 2–5 cm wide, with coarse serrations on the margins.
The slender leaf stalks are 2–5 cm long.
Racemes hang down from the upper leaf axils of the stem and bear 3–5 flowers.
The flowers are tubular, 3–4 cm long, and pale yellow.
There are reddish-brown spots inside the flower.
Behind the flower is a spur that stores nectar; its tip does not curl but hangs downward.
The flowers hang beneath the leaves on slender flower stalks.
It often bears cleistogamous flowers, which are pollinated while still in bud and become fruit.
The fruit is a spindle-shaped capsule 1.5–2 cm long; when a ripe fruit is touched, it splits open and scatters the seeds.
