Leptochilus pteropus (synonym Microsorum pteropus) is a species of aquatic or semi-aquatic fern, commonly known as Java fern (after the Indonesian island of Java). It is predominantly known from Malaysia, Thailand, Northeastern India and parts of South China. It is a highly variable plant, with several different geographic varieties and physical forms that vary in leaf size, texture and shape (such as the crested-leaved 'Windelov' or 'Trident' varieties). Found in its natural habitat growing attached to riparian roots and rocks, it can grow fully or partially submerged, provided its roots and rhizome remain wet. It is native to Australasian. In the garden it prefers full shade and loam soil. In UK gardens it needs subtropical warmth and glass protection in the UK (RHS H1b). Suggested uses include indoor plant. It tolerates neutral soils, moist conditions and north-facing aspects. Plant in well-drained soil in a suitable position. Water during establishment.
