Shrubby Mesembs are often difficult to identify with the help of literature. Once a more knowledgeable person has given you the right name, it usually seems hard to believe that you didn’t get there under your own steam.
This species is a case in point. Especially older plants are easily recognized: robust shrubs of up to a meter tall with the old inflorescences remaining on them for several years. These remains are hard and spiny, giving rising to the specific epithet.
R. pungens is a widespread species, occuring from Montagu to the Eastern Cape.
