Characteristics

Decorative evergreen shrubs, 60-200 cm tall, or rarely a small tree. Stems with red wood; branches brown, densely verrucose with pale grey, raised rounded lenticels. Galls often present, forming a globose body consisting of numerous subulate bracts. Leaves partly shed at time of flowering, narrowly elliptic, 2.5-5 cm long, 1-1.5 cm broad, apex and base obtuse to acute, margin sharply serrulate with the teeth and apex mucronate, thinly coriaceous, shiny, dark green, midrib distinct, reticulate-veined; petiole 1 mm; intrapetiolar stipules linear, bidentate, margin toothed. Flowers usually solitary or rarely binate, on short lateral spurs; pedicels 1 cm long at anthesis, 1.5 cm in fruit, articulated 1-2 mm above base. Sepals ovate, 8 mm long at anthesis, green, up to 15 mm long and deep wine red in fruit, spreading or reflexed. Petals broadly obovate, cuneate, 1 cm long. Stamens c. 20, with filaments c. 3 mm long; biporose anthers about equal in length. Carpels 5, attached basally; style terete with short, recurved tips; stigmas apical, discoid. Drupelets oblong-ovoid, c. 1 cm long, black. Flowering in spring, but with some flowers throughout the year.
