General Environment
This is a freshwatermarine species.
Description
The plants are 3-15 (30) cm high, encrusted or unencrusted and grey to green in colour. The axis is up to 500 µm in diameter. The internodes are 1-3 times longer than the branchlets. The branchlets are 7-8, each with 4-9 segments. The stem cortex is triplostichous, tylacanthous. The spine cells are solitary and papillous. The stipulodes in the upper row are well developed and acute, in lower row they are short to papillous. The bracteoles are 1-2 times as long as the oogonium. The plant is monoecious. The gametangia are conjoined at the three lowest branchlet nodes. The oogonium is up to 1.1 mm long, and up to 700 µm broad. The oospore is black. The antheridium is up to 350 µm in diameter. Multicellular bulbils are often found in this species.
Habitat
Chara virgata is common in freshwater but is occasionally found in brackish water. It is found in many different types of localities, from large lakes to ditches and streams. The water is from soft to calcareous, and often rich in electrolytes. The species can also tolerate competition from other water plants. It is often found in shallow water, growing on many types of bottom, from peat to marl and sand bottom. This is one of the most common charophytes in the area.
Chara virgata is commonly very rich fertile, and such plants can be found from May to late autumn, and ripe oospores which also are frequent are found from July.
The species is annual or perennial, depending on the depth of growth. Perennial forms have oospores through the spring
Key Characteristics
