Japanese name: ハマサジ（浜匙） Scientific name:Limonium tetragonum
[Overview]
A monocarpic perennial found in places on the coast that are submerged at high tide.
The stem is very short.
The leaves are simple and alternate, clustered at ground level, 8–17 cm long and 1.5–3 cm wide, oblong-spatulate, with the base gradually narrowing into a petiole-like part.
The leaves are thick and smooth, with entire margins.
A flower stalk 20–60 cm tall extends from the center of the leaves.
The flower stalk is much branched, and because the branches of the inflorescence are almost the same length, the whole forms a panicle-like inflorescence bearing many spikelets.
Each spikelet consists of one fertile flower and one sterile flower, enclosed by 2 bracteoles and 1 bract.
Of the bracteoles, the upper is large and the lower is small.
The calyx is white, tubular and membranous, shallowly 5-lobed, with ridges that bear hairs.
The corolla is longer than the calyx and deeply 5-lobed; the part emerging from the calyx is yellow.
The fruit is a fusiform achene, and the calyx persists until the fruiting stage.
