Environment

Marshy places, swamps, particularly along creeks in tall rain-forests, slopes of partially open virgin forests, and very common in secondary forests, from the lowland up to 2250 m.It clearly avoids regions subject to a seasonal climate as it is absent from Central Java to Timor; in Java it is confined to the Res. of Bantam, Bogor, and Preanger, one specimen being found in an everwet forest in S. Banjumas.Hosokawa found G. axillaris common in the mossy hill forest of the Micronesian islands Ponape and Kusaie together with Alsophila where it produces aerial roots from the boughs of the crowns ( Hosokawa Mem. Fac. Sc. Kyushu Univ. E 1 1952 65-82 )
