Many Adromischus species are quite variable and this one is no exception.
Looking at the pictures you will get some idea of the differences in size, colour, markings and shape of the leaves.
A. maculatus is often quite similar, but there the horny leaf margin runs all around the circumference of the leaves, whereas in A. triflorus it is only present in the upper half.
The species occurs on lower sandstone slopes and rocky outcrops from Clanwilliam to Worcester, Mossel Bay and Steytlerville; in the Little Karoo it is the most common Adromischus.
The relatively large flowers appear from November to January.
