A study on fern family Gleicheniaceae was carried out for Peninsular Malaysia. A total of 14 species including 10 varieties in 4 genera was identified and recorded, genus Dicranopteris (4 species, 7 varieties), Diplopterygium (5 species), Gleichenia (3 species) dan Sticherus (3 species, 3 varieties). These ferns were collected from the fringes of the Lowland Dipterocarp Forest (LDF), Hill Dipterocarp Forest (HDF), Lower Montane Forest (LMF) and Upper Montane Forest (UMF). Four species and 3 varieties were found to be widely distributed over 3 types of vegetation, the LDF, HDF and LMF. Three species were distributed over higher elevation from the HDF, LMF to UMF. One variety, Dicranopteris linearis var. altissima was only recorded from the LDF, whilst Diplopterygium giganteum and Gleichenia dicarpa were recorded only in the UMF. Dicranopteris linearis and Sticherus truncatus were found to be the most widely distributed G. Rusea • L. Y. Chin • H. Omar • M. Muskhazli • Y.

All species of Gleicheniaceae are terrestrial sun loving ferns and grew well on poor clay soils or poor nutrient soils. In fact, these ferns required small amount of mineral substances for growth. Members of this family mostly form thickets in open places, to which they are adapted to by their creeping rhizomes and the indefinite growth in length of scrambling or climbing fronds.
