Compared to ssp. corallina, these plants look more sturdy, with leaves 4-5 mm long and wide. The leaves are also much whiter.
Another difference is that they have a tuberous main root up to 1.2 cm wide (macrorrhiza= with a big root).
This subspecies has a generally more northern distribution, from the Grunau-Warmbad area in Namibia to adjacent parts in South Africa, from Vioolsdrift to Kenhardt, usually on coarse sandy flats.
The flowers appear from October to January.
Great pic Frans. I have seen both in habitat and they are really charming little plants. Best wishes, Robin
