Ceratophyllum demersum "Mexiko" ("Rotstängelig")

This nice variety of common hornwort is also known under the name Cerathophyllum demersum "Rotstängelig" ("red-stemmed"). It originates from Lake Catemaco in the east of Mexico.

In comparison with "standard" forms of C. demersum, C. demersum 'Mexiko' ramifies more readily when kept under the same conditions, and its stems are of a more intensive red colour.
