Where seen? A carpet of this succulent plant is sometimes
seen on undisturbed shores and back mangroves. The tiny flowers are
delicate and pink. According to Hsuan Keng, it is found on clay soil
near the seashores. According to Giesen, it is found throughout Southeast
Asia, but not (yet) recorded in Borneo. 'Gelang laut' means
'Garland of the Sea' in Malay. It is also called 'Sepit-sepit'.
Features: A spreading creeper
with many branches forming a carpet on the high shores of sandy beaches
and in back mangroves. Stems and leaves thick and fleshy. Stems up
to 1m long, smooth, sometimes bright red, and with roots at the nodes.
Leaves narrow fleshy flat (2.5-7cm). Tiny flowers at the leaf axils,
pale pink. The flowers close at night and when the sky is overcast.
Flowering occurs throughout the year. The fruit is a smooth, round
capsule containing tiny pea-shaped smooth black seeds. The seeds don't
float.
Small, pollen-collecting bees and day-flying moths pollinate the flowers.
Human uses: According to Burkill, the fresh leaves make
a very good vegetable, but only after cooking by 2-3 boilings as they
contain much salt. According to Geisen, in Thailand, this plant is
used widely as forage and feed for sheep, cattle and pigs and even
as a vegetable for human consumption.
