Habit:  aquatic fern

Description:  "Floating fern with hairy stems.  Uppermost (floating) leaves entire at apex, to 1.2 cm long, broader than long with margins curving upwards and inwards; upper leaf surfaces with papillae in irregularly curved rows, the tips not joined.  Sporocarps form on the submerged, rootlike lower leaves.  This species is similar to the serious weed Salvinia molesta.  The characters of S. molesta are leaves longer than broad with deeply indented leaf apices; the papillae hairs are joined at their tips to form a cage-like structure"  (Waterhouse & Mitchell, 1998; pp. 91-92).  See also Salvinia natans.

Habitat/ecology:  "Slow-moving freshwatrer bodies, rice fields" (Waterhouse & Mitchell, 1998; pp. 91-92).
