Here is an example of how knowing the meaning of the name actually may help to recognise the species. (Rhinephyllum = leaf like a file, referring to the rough surface of the leaves; graniforme = shaped like a grain). The genus occurs from Laingsburg in the Western Cape northeastwards to the southern tip of the Free State.
The flowers are rather special in the sense that they open only late in the afternoon or in the evening.

Hi Frans. I came across your bolg quite by chance the other day; signed up . . . and am now so enjoying your interesting posts and beautiful photos. Thank you very much for sharing such fascinating information with us all.
Thank you for your kind words. It is always gratifying to find out that people like what you are doing.
Great photos . . . I love viewing succulents in habitat, and these are particularly striking.
