Gaultheria adenothrix, known as アカモノ (akamono) or イワハゼ (iwahaze), is a small evergreen shrub in the Ericaceae. It is one of three Gaultheria species native to Japan and grows in low-mountain to subalpine areas.

Description

Gaultheria adenothrix is an evergreen shrub growing in clusters 10–30 cm in height. It produces subterranean creeping stems as well as aerial stems. The biennial leaves, 1–2.5 cm long and 0.7-2 cm long, are alternate and broadly ovate with serrate margins. The petioles are 1-2 mm long. The veins are slightly depressed on the upper surfaces of the leaves.

Each branch contains 1–4 nodding urceolate flowers, and there is a solitary flower on the upper leaf axil. The corolla, 6–8 mm in size, is white to faintly pinkish-white and shallowly five-lobed with slightly reflexed margins. The abaxial surface of the petals has a reddish midrib. The calyx is 3–4 mm long, vivid red and comprises 5 triangular-ovate lobes. The pedicels are 1.5–3mm long. Each flower contains 10 stamens, each around 2 mm long with awnless anthers. The pistil is 4–5 mm long and glabrous with a depressed globose ovary around 1.5 mm in diameter. The young stems, petioles, pedicels, and sepals have long hairs.

After anthesis, the calyx grows, envelops the capsule, and becomes a spherical pseudofruit 6–7 mm in diameter that turns red as it ripens. The pseudofruit is edible and has a sweet taste. The seeds are compressed ellipsoids, 0.5–0.8 mm in length and lustrous. G. adenothrix flowers from July to early August in the alpine zone in central to eastern Japan and in May to June in the montane zone in western Japan.
