About Common horsetail (Equisetum arvense L.)

A spore-forming, herbaceous plant of the family Equisetaceae. Spring sporulating stems up to 20 (40) cm tall, 3-5 mm in diameter, light brown or reddish in colour, succulent, usually with five spaced funnel-shaped sheaths. The vagina has 8-12 denticles, 2-3 of which are clasped together and about the length of the vaginal tube. Sporangial penises up to 3,5 cm long; the axis of the penis is full. The vegetative stems grow later, up to 50 cm tall, 3 mm in diameter, with 6-19 longitudinal ribs. Fls 5-12 mm long, slightly protruding from the stem in the upper part; their denticles are twice as short as the tube, triangular-lanceolate, greyish, with white margins. Branches are usually four- or five-trunked (rarely six-trunked), usually erect, sometimes branched. The teeth of the sheaths are recurved, triangular, pointed. Sporulates in April-May.
