General Environment
This is a brackish species.
Description
The plants are up to 30 cm long, green, unencrusted. The axis is up to 1 mm in
diameter. The branchlets are 7-10 in each whorl, each with 5-8 segments. The stem
cortex is diplostichous, aulacanthous. The spine cells are longer than the stem
diameter, 2-6 together of which some can be very short. The plants are very spiny.
The stipulodes are in 2-3 irregular rows. The posterior bract cells are as long as the
anterior bract cells. The species is monoecious. Gametangia are not common.
Oogonia are large and up to 1.3 mm long. The oospore is black. The antheridia are
red and up to 500 m in diameter.
Chara horrida can be difficult to separate from C. baltica. C. horrida has
ecorticated end segments which always are short, while they are elongated in C.
baltica.
Habitat
Chara horrida is a brackish water species, and is found in water with salinity
between 5.5 and 8 PSU. It grows on soft bottom, down to 3 m depth.
The species has low fertility, and sterile specimens are common. Fertile plants are
found from June to September. Oospores are rare.
