VALLESIA (name commemorative of Francisco Valles, physician to Philip II. of Spain; he died in 1592). ORD. Apocynaceae. A small genus (two species) of American, much-branched, glabrous, stove shrubs or small trees. Flowers small, cymose; calyx five-parted, without glands; corolla salver-shaped, annulate or pilose within the throat, the lobes five, ovate or lanceolate, twisted; stamens included below the apex of the tube. Leaves alternate, lanceolate or oblong. It is doubtful whether VALLESIA dichotoma is still in cultivation. A compost of sandy loam and peat suits it. Propagation may be effect by means of cuttings, inserted in sand, under a glass, in heat. VALLESIA dichotoma (dichotomous). fl. white, 1/3in. long, numerous; cymes dichotomous, half the length of the leaves. May. l. ovate-oblong, acute, obtuse at base, 2in. to 2 1/2in. long, rugose-tubercled and pellucid-dotted; young ones pubescent. Branches dichotomous, terete. h. 3ft. Peru. 1822.
