Trichodiadema setuliferum is a succulent plant of the genus Trichodiadema, native to the Karoo regions of the Cape Provinces, South Africa.
Description
[edit]
It is a small, gracile, semi-erect plant, with long and minutely-papillate internodes.
The leaves can reach a length of 24 mm, and are covered in bladder cells that have apically curving hair-like papillae.
Apically the leaves are slightly recurved, and each has a diadem of up to 16 yellow-orange bristles.
The flowers are pink to magenta.
Related species
[edit]This species is very similar to the partly syntopic Trichodiadema pomeridianum and Trichodiadema rogersiae.
T. setuliferum can be distinguished from the other two by its papillate bladder cells; while those of the other two species are smooth and without papillae.
In addition, Trichodiadema pomeridianum has much shorter leaves (only c.15 mm), while Trichodiadema rogersiae is a smaller plant with thicker, stronger branches. There are also fewer diadem bristles on both Trichodiadema pomeridianum (only 3-8) and Trichodiadema rogersiae (only 5-9). [1][2]
