Saphesia flaccida is the only type of monotypic genus Saphesia from the family of aizoaceae (Aizoaceae). The botanical name of the genus is derived from the Greek word saphes for 'different' and indicates that the genus is clearly different from all others in the family.

description

Saphesia flaccida grows as a perennial or biennial plant with a thick, branched rhizome and up to 1 meter long branched shoots and deciduous branches. The opposite or alternate arranged light green leaves are flat and slender. They are not grown together at their base. Your epidermis contains dispersed bladder cells .

The individual flowers have five sepals , white petals and reach a diameter of 3.5 to 4.5 centimeters. They stand on 4.5 to 21 centimeters long flower stalks . The nectarium forms a slightly lophomorphic ring. The flowering period extends from September to November.

The valves of the xerochastic , five-compartment fruit do not separate from the septum. In contrast to all other members of the subfamily of the Ruschioideae , they form a distal ring along the outer edge in which the septum and ovules protrude and thus form sections in which a seed grows. The dark brown seed coat is covered with low papillae .

Systematics and distribution

Saphesia flaccida is common in South Africa in the western districts of the Western Cape Province . It grows near the sea in areas with year-round rainfall of more than 400 millimeters per year.

The first description of the species as Mesembryanthemum flaccidum by Nikolaus Joseph von Jacquin was published in 1804. Nicholas Edward Brown placed this species in 1932 as the only species in the genus Saphesia newly established by him .
