The vermilion flowers of Halleria lucida can be borne directly from the trunk or branches. Plants are sometimes shrubby, but on the slopes of Table Mountain it forms trees. Image G. Duncan.

Formerly placed in Scrophulariaceae, Halleria comprises four species, two in tropical and southern Africa and two in Madagascar. They are small trees or shrubs with quadrangular or winged stems. The leaves are opposite, petiolate, ovate or elliptic and dentate to almost entire. The flowers are produced in axillary clusters, with a three- to five-lobed cup-shaped calyx, a campanulate corolla, four- to five-lobed, red to orange, tube elongated, curved or straight, and four stamens. The fruit is a fleshy berry; the seeds narrowly winged (Philcox 1990, Fischer 2004).
