Flowers on slender, erect, often reddish, glandular-downy stalks 1⁄2 to 1 in. long, which are produced singly in from three to seven of the terminal leaf-axils in early May. Corolla open bell-shaped, about 1⁄4 in. long, rather more wide, with shallow, rounded lobes; white tinged with pink on the lobes; sepals about 1⁄12 in. long, pointed, ciliate, glabrous on the back, often reddish. Stamens and style enclosed within the corolla. Seed-vessel globose, depressed at the top where it is roughened with short, hardened glandular hairs. Bot. Mag., t. 8405.
This delightful little shrub, one of the daintiest of the heath family, is a native of Japan. It flowered at Kew in 1911, but owing to some misplacement of labels its history was lost, and it was described as a new species by Dr Stapf. It received a First Class Certificate in 1946.
