Mesembryanthemum theurkauffii is an
annual succulent plant of the Aizoaceae family, commonly known in the
Canary Islands as ‘cosco de Jandía’. It is a protected native species in
the Canary Islands and is native to the arid regions of north-western
Africa.
It is a creeping, highly succulent herbaceous plant with an
annual life cycle. Its stems may be short and erect or long and
prostrate on the ground.
The leaves are opposite, cylindrical, fleshy
and lack petioles (sessile). Their surface is covered with fine
crystalline papillae, and they change colour in response to sunlight or
water stress, ranging from green to ochre or pink.
Flowers are
solitary, found in the leaf axils, and measure between 13 and 15 mm in
diameter. They have petaloid staminodes that are white or
yellowish-white in colour.
It develops a pentalocular (5-locular)
capsule which tends to become woody and has the distinctive feature of
expanding into a star shape when moistened to release its seeds.
In
Spain, it is found growing wild only on the island of Fuerteventura,
concentrated in very specific locations such as the area around the
Jandía lighthouse, the southern part of the Barranco de La Torre and the
Ensanada del Castillo.
It thrives best in arid, stony and sandy soils
exposed to strong sunlight. Its main flowering period occurs during the
spring months, between March and June.
