Trichodiadema pomeridianum | |
Trichodiadema pomeridianum ("Perde vygie") is a succulent plant of the genus Trichodiadema , widespread in the arid central Karoo regions of South Africa.
It grows as a loosely branching semi-erect shrublet up to 30 cm 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]
The Aizoaceae, or fig-marigold family, is a large family of dicotyledonous flowering plants containing 135 genera and about 1800 species. They are commonly known as ice plants or carpet weeds. They are often called vygies in South Africa and New Zealand. Highly succulent species that resemble stones are sometimes called mesembs.
Delosperma is a genus of around 170 species of succulent plants, formerly included in Mesembryanthemum in the family Aizoaceae. It was defined by English botanist N. E. Brown in 1925.
