"Graptophyllum pictum (L.) Griff., Acanthaceae, caricature plant: Shrub to 2 m tall. Leaves evergreen, opposite, glabrous and glossy, ovate to elliptic, to 6" long, dark green but blotched or marbled with yellow in the central zone and with pink midveins and petioles. Inflorescence in short axillary or terminal racemes or panicles. Flowers tubular, 2-lipped, inflated at the throat, about 1½" long and with 2 protruding stamens. Some cultivars with red, rose, or purple markings on the leaves. Originally from New Guinea, this species is grown in greenhouses or in warm humid regions. "
