Marsilea hirsuta

Marsilea hirsuta is a carpet-plant from Australia. A fascinating plant, usually delivered with leaves like a four-leaf clover. After a transitional period it develops different types of leaves, possibly a low form with single leaves like a large Glossostigma, or alternatively develop two, three or four-lobed leaves varying in height (from 2-10 cm), depending on the growth conditions. Whichever form the plant adopts, it forms runners and spreads rapidly round the aquarium.
