FIGURE 3. A in Kalanchoe steyniae (Crassulaceae subfam. Kalanchooideae; K. [subg. Kalanchoe sect. Raveta] ser. Rotundifoliae), a new, small-growing, shrubby species from eastern southern Africa

FIGURE 3. A. Lateral view of flowers of Kalanchoe steyniae (left) and K. rotundifolia (right). Note the much longer, very strongly reddish-infused sepals of K. steyniae. Scale bar = 10 mm. B. Frontal view of the corolla mouth of K. steyniae (left) and K. rotundifolia (right). The uniformly bright crimson red, narrowly lanceolate-falcate corolla lobes of K. steyniae are strongly recurved, as here, or spread at a 90° angle. Scale bar = 10 mm. C. The yellow- to orangey yellow-flowered K. alticola has sepal lobes of 4–7 mm in length. D. Kalanchoe steyniae often occurs on very rocky substrates, as here in Lebombo Summit Sourveld vegetation. E.
