Mitrophyllum
Mitrophyllum is a genus of succulent plants of the family Aizoaceae, indigenous to the arid region around the Richtersveld, on the border of South Africa and Namibia. Description. The species generally grow stems, at the top of which two succulent leaves appear. Similar to the closely related genera of "Monilaria" and "Meyerophytum", these leaf-pairs alternate consecutively between two different types of leaf-growth (heterophylly) and during the exceptionally hot summer they remain inactive in a dry sheath. When fused together into a cone-shaped corpuscle, this leaf pair is referred to as the plant's ""mitre"", and this  is the origin of the genus name. The two separate leaves of the free leaf-pair are rounded-triangular to tongue-shaped. The fused leaf-pair forms a cone-shaped to cylindrical corpuscle, which bears two smaller ear-like anthers at the top. This fused corpuscle dries out in the plant's dormancy period, eventually becoming a papery sheath in which the new (separate) leaf-pair forms. Cultivation. In cultivation, the plants are not difficult to grow. However they require deep well-drained sandy soil and sufficient sun exposure. They are also adapted to very dry summers and watering mainly  over the winter. Their period of growth is primarily over late autumn and winter. They are slow growing, maturing over many decades, and are difficult to propagate by cuttings; consequently seed is the preferred means of propagation.
