| + | Vinca rosea, Linn. Madagascar Periwinkle. Fig. 3934. Tender erect ever-blooming plant, somewhat shrubby at the base: lvs. oblong, narrowed at base, veiny: petiole glandular at the base: fls. with a very small orifice, rosy purple or white, the latter with or without a reddish eye; calyx-lobes linear, corolla-lobes dimidiate-obovate, mucronulate. Cosmopolitan in the tropics. Gn.36. p. 455; 43, p. 389. V. 13:49; 16:49. B.M. 248. F.R. 1:141. G. 11:197; 14:333; 37:205.—This is commonly called the "Madagascar periwinkle," but V. rosea is probably not native to the Old World, while the only species of Vinca that is really native to Madagascar, viz., V. lancea, is not in cult. The plant is sometimes called "Cape periwinkle" and "old maid." The three main types should be known as V. rosea, V. rosea var. alba, V. rosea var. oculata, the latter being a white fl. with pink or red center. As a matter of fact, these appear in American catalogues as V. alba, V. alba pura, V. alba nova, V. oculata, and V. varius, the last being a trade name for seed of mixed varieties. Var. delicata, Hort., is a trade name. |
