Kneiff's Hook-moss - Drepanocladus aduncus

Two main forms occur, although these are connected by a series of intermediates. One is many centimetres long, dark green, sparsely branched, with about 5 mm long, tapering, straight or slightly curved leaves, and floats in shallow pools and ditches. The other form is lighter green, smaller, upright and well-branched, has strongly curved leaves and favours temporary wetlands. Capsules are very rare.

D. aduncus is locally abundant in lowland pools, ditches and fens, especially in clayey parts of England. The large plants typical of these permanent wetlands are also found in mineral-rich dune slacks. Smaller forms grow in temporary wetlands, such as shallow pools in gravel pits, on quarry floors or in wet pastures. It is the only common lowland Hook-moss.

All year round.

It appears to be widespread and fairly frequent in Britain.

Status in Leicestershire and Rutland not known.
