Conophytum ectypum ssp. sulcatum TS 468 (north of Animub)
This is an autumn flowering taxon, but is always one of the last conos to crack out from its old sheath. Steve Hammer likens the body shape to a "pulled molar tooth" and that shape can even be seen in the dried sheaths. It causes me no problems to grow but some friends do have difficulties with it. In the wild, the typical form is confined to a hill called Animub and also nearby quartz flats; this is located between Steinkopf and the Orange River. There is also another very interesting collection by a Czech enthusiast from a little further south that has very small heads and white flowers.
