(From Henslow's " South African Flowering Plants ".) buds and blue flowers, or from yellow through bluish to violet. In Echium the change is from red through violet to blue. This, says Herman Muller, suggests that white, yellow, and red flowers were the ancestors of violet and blue flowers. Heliotrope belongs to this order. Order Sol.\n.^ce-E. Calyx 5-parted, persistent (except Datura). Corolla con- volute. I^etals plaited in bud. Stamens 5, alternate with and upon the petals. Carpels 2, placed obliquely in the flower. Flowers solitary or in cymes. Herbs, shrubs, or small trees. I'ruit a capsule or berry. Leaves exstipulate, alternate (whorled in Retzia). In the flowering portions the leaves appear more or less opposite. This is due to a peculiarity of growth. A leaf remains adnate 23.
