Monilaria is a plant kind from the family of aizoaceae (Aizoaceae). The botanical name of the genus is derived from the Latin word "monile" for string of pearls .
description
The species of the genus Monilaria grow as sparsely branched, deciduous shrubs with a stature height of up to 20 centimeters. Their short, thickened internodes reach a diameter of 10 to 20 millimeters. The first pair of leaves of the year is completely fused, more or less hemispherical, has a small tip slightly keeled on the underside and forms an almost spherical body of up to 10 millimeters. The second pair of leaves is about 10 centimeters long and 3 to 5 millimeters wide. It is flattened at the top and only grown together over about a tenth of the length. The epidermis contains bladder cells of various shapes and sizes .
The individual, stalked, terminal flowers appear from the second pair of leaves. Your papilose flower stalk is up to 10 centimeters long. There are 5 sepals arranged in a spiral shape . The petals and the thread-like staminodes are white, salmon-colored, rose-pink or purple-red.
The capsule fruits are 5 (rarely 6) -fabricated. Your source ridges are divergent, the wing covers are wide. Closure bodies are missing. They contain egg-shaped, smooth seeds .
The chromosome number is 2n = 18, 36.
Systematics and distribution
The distribution area of the genus Monilaria extends from Namaqualand in the South African province of Northern Cape to the places Vanrhynsdorp and Vredendal in the province of Western Cape . The plants grow on quartz-covered plains. The annual rainfall is less than 200 millimeters, with the majority falling in winter.
The first description was published in 1929 by Gustav Schwantes . The holotype is Monilaria chrysoleuca . According to Hans-Dieter Ihlenfeldt (* 1932) the genus Monilaria includes the following species:
- Monilaria chrysoleuca (Schltr.) Schwantes
- Monilaria moniliformis (Thunb.) Ihlenf. & S.Jorgensen
- Monilaria obconica Ihlenf. & S.Jorgensen
- Monilaria pisiformis (Haw.) Schwantes
- Monilaria scutata (L. Bolus) Schwantes
