(from xysma, a fragment, and lobos, a division; alluding to the minute divisions of the corona). ORD. Asclepiadeae. A genus consisting of about eight species of stove or greenhouse, perennial herbs, natives of tropical and South Africa. Flowers in umbelliform cymes; calyx five-parted, having five or many glands at the base within; corolla somewhat rotate-campanulate, five-cleft, the lobes reflexed-bearded or naked within; coronal scales five, affixed to the staminal tube. Leaves opposite, broadly lanceolate or linear. X. padifolium, the only species known in gardens, requires similar treatment to that recommended for Gomphocarpus. X. padifolium (Cherry-leaved).
