FIGURE 1 in Kalanchoe ×sampsonii [K. ×hankeyi × K. sexangularis] (Crassulaceae subfam. Kalanchooideae), a horticulturally successful nothospecies from South Africa with enhanced vegetative and reproductive characters

FIGURE 1. Kalanchoe ×hankeyi (A–B) and K. sexangularis (C–D). A. Leaves of K. ×hankeyi are light green to strongly red-infused, especially when grown in full sun. The marginal leaf crenations of K. ×hankeyi are situated more towards the upper parts of the leaf margins, as in one of its parents, K. longiflora, rather than virtually along the whole margin, as is found in the other parent, K. sexangularis. B. Flowers of K. ×hankeyi have yellow corolla lobes and a greenish yellow tube. C. Leaves of K. sexangularis turn a bright crimson red when exposed to high levels of solar irradiation. D. As in the case of K. ×hankeyi, flowers of K. sexangularis have a greenish yellow corolla tube and yellow corolla lobes. All photographs taken by Gideon F. Smith.
