Conophytum ernstii

A small clump-forming Conophytum from the winter-rainfall Succulent Karoo of the Northern Cape (Namaqualand). Like the rest of the genus it grows in the cool, foggy months and rests through the hot summer inside papery old leaf sheaths; get that cycle right and it is straightforward.

Where it grows wild

Little is published for this species; the genus grows wedged into rock crevices and quartz or gravel flats in open succulent scrub, roots in pockets of mineral grit, often catching coastal fog and dew.

The single georeferenced record sits on the Namaqualand coastal plain near sea level; the genus spans sea level to the escarpment.
