Salicornia procumbens pojarkovae (Salicornia procumbens pojarkovae)
Description
The Salicornia species are small annual herbs. They grow prostrate to erect, their simple or branched stems are succulent, glabrous, and apparently jointed. Older stems may be somewhat woody basally. The opposite leaves are fleshy, glabrous, sessile, basally connate and decurrent and enclosing the stem (thus forming the joints). The leaf blades are reduced to small collar-like scales with narrow scarious margin. Many species are green, but their foliage turns red in autumn.All stems are terminating in spike-like apparently jointed inflorescences. Each joint consists of two opposite minute bracts with an (1-) 3-flowered cyme tightly embedded in cavities of the main axis and partly hidden by the bracts. The flowers are arranged in a triangle, both lateral flowers beneath the central flower. The hermaphrodite flowers are more or less radially symmetric, with a perianth of three fleshy tepals connate nearly to the apex. There are 1-2 stamens and an ovary with two stigmas. The perianth is persistent in fruit. The fruit wall (pericarp) is membranous. The vertical seed is ellipsoid, with yellowish brown, membranous, hairy seed coat. The seed contains no perisperm (feeding tissue). Like most members of the subfamily Salicornioideae, Salicornia species use the C3 carbon fixation pathway to take in carbon dioxide from the surrounding atmosphere.
