FIGURE 2 in Kalanchoe ×oberlanderi (Crassulaceae subfam. Kalanchooideae), a horticulturally successful nothospecies with the Malagasy K. blossfeldiana and K. manginii as parents

FIGURE 2. Kalanchoe ×oberlanderi. A. The shape of the leaves of K. ×oberlanderi is intermediate between that of K. blossfeldiana and K. manginii, with the leaves of K. ×oberlanderi generally being larger than those of K. manginii, but smaller than those of K. blossfeldiana. Leaf margins of K. ×oberlanderi are often weakly crenate especIally In the upper ⅔. B. The weakly campanulate and very finely pubescent flowers are variously borne erectly to pendent, but are usually spreading. C. The corolla tube varies from bright crimson red to lighter red to pinkish (see 'D.' for the size of the flowers). D & E. Comparison of the flowers of K. blossfeldiana (throughout the flower on the left), K. ×oberlanderi (throughout the flower in the centre), and K. manginii (throughout the flower on the right). D. Lateral view (see Table 1 and 'Results' for a discussion), with the flowers of all three taxa here arranged vertically. E. Colour and ornamentation of the adaxial corolla lobe surface (see Table 1 and 'Results' for a discussion). F. When K. ×oberlanderi is in full flower during the winter months, the floral display is spectacular. All photographs: Gideon F. Smith.
