Flowers red, large, showy; peduncles axillary, terete, one-flowered, naked, opposite or solitary, shorter than the leaves, usually with brown tomentum.

They thrive well in peat, or a mixture of loam and peat, and require to be liberally supplied with water, particularly in spring and summer.

June. l. oval-oblong, three-nerved, glabrous and shining on both surfaces in the adult state, and when young serrulated; petioles and branchlets clothed with rusty tomentum. Roots issuing from the branches and stems. h. 4ft. to 8ft. Jamaica, 1789. (B. M. 451.)
