Pseudopyxis depressa f. angustiloba("Hoshizakiinamoriso")
Japanese name: ホシザキイナモリソウ（星咲稲森草） Scientific name:Pseudopyxis depressa f. angustiloba
[Overview]
A perennial 3–5 cm tall, found in forests and similar places in the mountains.
It has thin creeping rhizomes.
The stem is erect and covered with short, curved soft hairs.
The leaves are simple and opposite, but because the two upper pairs of leaves are close together, they look as if they were in whorls of four.
The leaves are ovate, 1–6 cm long and 1–4 cm wide.
Both surfaces of the leaves bear sparse short soft hairs, which are more numerous on the veins of the underside.
It has triangular stipules.
The petiole is 0.1–0.3 cm long and covered with short soft hairs.
The flowers are borne singly in the leaf axils, or one or two at the tips of the branches.
The flowers are pale reddish purple; the corolla is divided into 5–7 lobes at the tip, and because the lobes are narrow and their margins fold inward, the flower looks star-shaped.
The inside of the corolla has short hairs.
There are 5 stamens with short filaments.
The fruit is a capsule, borne upward on a short stalk, with the triangular calyx lobes spreading straight out in a star shape.
[History]
It was discovered on Mt. Takao by Makino Tomitaro and published in 1926.
