Lampranthus is a genus of plants fromthe afternoon flower family (Aizoaceae). The botanical name is derived from the Greek words lampros for 'shining' and anthos for 'blossom' and refers to the brightly shining flowers of most species.
description
The species of the genus Lampranthus are upright to creeping shrubs , often with noticeably red shoots. Their paired, cylindrical or three-sided leaves are almost not fused together and only moderately xeromorphic. They are up to 2 inches long. The leaf surface is smooth and only occasionally spotted.
The flowers appear individually or in larger dichasias and are usually on short stems. They reach a diameter of up to 6 centimeters. There are five sepals . The numerous petals are often shiny and brightly colored. They are white, yellow, orange, red, or purple. Filamentous staminodes are usually present. The nectarium forms an inconspicuous, finely notched ring.
The five-compartment, dark brown capsule fruits have a long persistence. Their base is long funnel-shaped to bell-shaped, the tip raised. The mostly rectangular flap wings are large. The swelling strips diverge, the fan ceilings are strong. Closure bodies are not available. The fruits contain brown, pear-shaped seeds that are more or less smooth to a little papilla .
distribution
The distribution area of the genus Lampranthus extends in a wide band along the coast starting south of Lüderitz in Namibia over the South African provinces of Eastern Cape , KwaZulu-Natal , Namaqualand , and the provinces of Northern Cape and Western Cape . The majority of the species grow in the winter rain areas near the Cape of Good Hope . The species are distributed in very different habitats . They grow in sandy locations along the coast or on slate or clay plains. They are often found in rocky areas and on sandstone floors.
Systematics
The first description of the genus by Nicholas Edward Brown was published in 1930. The type species is Lampranthus multiradiatus . The genus Lampranthus includes the following species:
