“Suaeda”的意思、由来-开放百科全书

Suaeda is a genus of plants also known as seepweeds^[1] and sea-blites. Most species are confined to saline or alkaline soil habitats, such as coastal salt-flats and tidal wetlands. Many species have thick, succulent leaves, a characteristic seen in various plant genera that thrive in salty habitats (halophile plants).

The most common species in northwestern Europe is Suaeda maritima. It grows along the coasts, especially in saltmarsh areas, and is known in English as common seablite. It is also common along the east coast of North America from Virginia northward. One of its varieties is common in tropical Asia on the land-side edge of mangrove tidal swamps. Another variety of this polymorphic species is common in tidal zones all around Australia (Suaeda maritima var. australis is also classed as Suaeda australis). On the coasts of the Mediterranean Sea a common Suaeda species is Suaeda vera (synon. S. fruticosa). This is known as "shrubby sea-blite" in English, in distinguishment from common sea-blite. It grows taller and forms a bush.

The name Suaeda comes from an Arabic name ({{lang|ar|سُوَيْدَاء}} {{Italics correction|suwaydāʾ}}) for the Suaeda vera species and it was assigned as the genus name by the 18th century taxonomist Peter Forsskal during his visit to the Red Sea area in the early 1760s.^[2]^[3]^[4]

The genus includes plants using either {{C3}} or {{C4}} carbon fixation. The latter pathway evolved independently three times in the genus and is now used by around 40 species. Suaeda aralocaspica, classified in its own section Borszczowia, uses a particular type of {{C4}} photosynthesis without the typical "Kranz" leaf anatomy.^[5]^[6]^[7]

Uses

In the medieval and early post-medieval centuries it was harvested and burned, and the ashes were processed as a source for sodium carbonate for use in glass-making; see glasswort. In Mexico, some species such as Suaeda pulvinata are cooked in traditional dishes known as romeritos.
