Description
It grows as a loosely branching semi-erect shrublet up to 30cm high. The internodes are long, and rough from minute white papillae.
The leaves are ca. 15 mm long and ca. 2 mm wide. The leaf surfaces are densely covered in bladder cells that do not have papillae (except at the basal leaf margins). The leaf tips have simple diadems of 3-8 yellow bristles, radiating from similarly yellow cup cells.
The petals are pink-to-purple in colour, and born in two series.
This species is easily confused with T. setuliferum, which however has much longer leaves (reaching 24mm).[1] [2]
