Honckenya (Honckenya)
Description
Honckenya peploides, the sea sandwort (UK) or seaside sandplant (Canada), is the only species in the genus Honckenya of the flowering plant family Caryophyllaceae. Other common names include sea chickweed, sea pimpernal, sea-beach sandwort, and sea purslane. The scientific name is often spelled "Honkenya", and is named after the German botanist Gerhard August Honckeny (or Honkeny). This plant has a circumboreal distribution. The plant is a succulent perennial growing at the edge of the sea. It has small greenish white pentamerous flowers with 10 stamens in the male flowers borne in the leaf axils. The fruit capsule opens in three valves. Honckenya peploides is a small, subdioecious, spreading plant, forming patches on sand and shingle above the high water mark of beaches. The stem is branching and buried in the sand. The leaves grow in opposite pairs and are fleshy with membranous margins, pale yellowish-green and ovate, oblong or lanceolate, usually with pointed tips. The flowers are often dioecious and have parts in fives. They grow in the upper leaf axils and have ovate to lanceolate sepals, greenish-white petals of about the same length, and three styles. The fruit is a capsule larger than the sepals and superficially resembling a pea. In pistillate flowers the stamens are undeveloped while in staminate flowers, the capsules are poorly developed.
