Marsilea Hirsuta, originally from Australia, is an easy and fascinating ground cover. Variable height between 2 and 10 cm. In trade, it often has quadrifoliated leaves, which take different forms as soon as the plant has adapted to its new environment. It can have low stems crowned with simple leaves that look like a great glossostigma, but it can also have composed leaves (bifolied, trifoliated or quadrifoliated) from different heights, it all depends on the growth conditions offered to it.
But whatever the form it takes, it is a plant that spreads quickly by ramifications.
