Common names

(as Chara horrida L.J.Wahlstedt)
Swedish: Raggsträfse (Tolstoy & Österlund 2003).

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.

Type information
Type locality: Europe (Silva 1996-to date).
