[HAW] S. powellii

In some regions where S. robusta and S. arborescens occur together, natural
hybrids have evidently arisen, one of them probably described as S.
powellii. Definite proof for this assumption is still awaited, for
artificial hybrids of these two species are as yet only 10 cm high. In S.
powellii the fleshy leaves, up to 80 cm long, are also arranged fanwise as
in S. robusta, but they are more or less twisted along the stem which may
reach a height of 2 m in mature plants after many years. Should the plant
grow too tall, one can cut the top off and re-root it.

Coming next - S. kirkii
