Original description:  

Type Species
This is the type species (lectotype) of the genus Chara.

Status of Name
This name is of an entity that is currently accepted taxonomically.

Origin of Species Name
Adjective (Latin), common, general, ordinary (Stearn 1973).

General Environment
This is a freshwater species.

Description
The plants are from 10 to 50 cm high, axis is from 0.5 to 1 mm in diameter, moderately to heavily encrusted, often grey to dark green in colour. The branchlets are 7-9, each with 6-8 segments, of which 2-3 often are ecorticated. The stem cortex is diplostichous and aulacanthous (fig. 6). The spine cells are always solitary, from papillous to as long as the axis diameter (f. papillata). The species is monoecious. The gametangia are conjoined at the 3-4 lowest branchlet nodes. The oogonium is to 900 µm long. The oospores are normally brown, but is black in one of the varieties. The antheridium is up to 500 µm in diameter. Chara vulgaris is a highly polymorphic species, and many forms and varieties have been described.

Habitat
Chara vulgaris is a freshwater species but has also been found in slightly brackish water. The species is found in a large spectre of habitats, ponds, puddles, ditches, rivers, littoral pools and periodical waters. Very few finds are from lakes. It is found both in soft and alkaline water and it grows down to 1 m. Both annual and perennial forms occur. Plants surviving the winter will often give rise to new shoots the next year. Chara vulgaris is often richly fertile.
