Summary
[edit]DescriptionCheiridopsis peculiaris (Aizoaceae) (40422807135).jpg |
ǀAi-ǀAis/Richtersveld Transfrontier Park, Sendelingsdrif Nursery, Northern Cape, South Africa Cheiridopsis peculiaris is a strictly endemic and critically endangered species found only in one area of South Africa just to the west of Steinkopf in the south-eastern Richtersveld. The plant makes two sorts of leaves borne in 2 pairs, each of a different shape. The longer lower leaves up to 5 cm long, broadly triangular-ovate united at the base are produced during the growing season and lie flat on the ground, with flattened upper surface, they dry up to eventually become papery. The upper resting and shorter leaf pairs are upright and entirely united, forming a pointedly or blunt cone and encloses completely the new long leaf-pairs during the dry season. They are grey-green to purplish with darker dots on the sides. At the base of the leaf pair there is a persisting sleeve-like sheath, that is the remnants of the older leaves. |
