It is commonly known as shoreline purslane or (ambiguously) "sea purslane," in English, dampalit in Tagalog and 海马齿 hǎimǎchǐ in Chinese.

Sesuvium portulacastrum is vine up to 30 centimetres (12 in) high, with thick, smooth stems up to 1 metre (3.3 ft) long. It has smooth, fleshy, glossy green leaves that are linear or lanceolate, from 1–7 centimetres (0.39–2.76 in) long and 2–1.5 centimetres (0.79–0.59 in) wide.

Its flowers come from at the leaf axils, they are tiny, 0.5 centimetres (0.20 in) in diameter and pink or purple in colour. They close at night time or when the sky is cloudy, they are pollinated by bees and moths.

The fruit is a round capsule, it has tiny black seeds that do not float.

It was first published as Portulaca portulacastrum by Carl Linnaeus in 1753. Six years later Linnaeus transferred it into Sesuvium, and it has remained at that name ever since, with the exception of an unsuccessful 1891 attempt by Otto Kuntze to transfer the species into a new genus as Halimus portulacastrum.

Fatty acid composition:- palmitic acid (31.18%), oleic acid (21.15%), linolenic acid (14.18%) linoleic acid (10.63%), myristic acid (6.91%) and behenic acid (2.42%) The plant extract showed antibacterial and anticandidal activities and moderate antifungal activity.

 

 

Sesuvium portulacastrum is eaten in the Philippines, where it is called dampalit in Tagalog and "bilang" or "bilangbilang" in the Visayan language. The plant is primarily pickled and eaten as atchara (sweet traditional pickles).
