Sesuvium portulacastrum
Template:Short description Template:Speciesbox
Sesuvium portulacastrum is a sprawling perennial herb in the family Aizoaceae that grows in coastal and mangrove areas throughout much of the world.[1] It grows in sandy clay, coastal limestone and sandstone, tidal flats and salt marshes,[2] throughout much of the world. It is native to Africa, Asia, Australia, Hawai`i, North America and South America, and has naturalised in many places where it is not indigenous.[3]
It is commonly known as shoreline purslane[4] or (ambiguously) "sea purslane," in English, dampalit in Tagalog and Script error: No such module "Lang". hǎimǎchǐ in Chinese.
Description
Sesuvium portulacastrum is a vine up to Script error: No such module "convert". high, with thick, smooth stems up to Script error: No such module "convert". long. It has smooth, fleshy, glossy green leaves that are linear or lanceolate, from Script error: No such module "convert". long and Script error: No such module "convert". wide.[5][2]
Its flowers bud from the leaf axils. They are small, Script error: No such module "convert". in diameter and pink or purple in colour.[5][2] They close at nighttime or when the sky is cloudy. They are pollinated by bees and moths.[1]
The fruit is a round capsule, it has tiny black seeds that do not float.[1]
Taxonomy
It was first published as Portulaca portulacastrum by Carl Linnaeus in 1753.[6] Six years later Linnaeus transferred it into Sesuvium,[7] 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.[8]
Chemistry and medicine
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.[9]
Human consumption
Sesuvium portulacastrum is eaten in the Philippines, where it is called dampalit in Tagalog and "bilang" or "bilangbilang" in the Visayan language.[10] The plant is primarily pickled and eaten as atchara (sweet traditional pickles).
