Identification. Hay (1998) treats A. longiloba as an ochlospecies (species which exhibits a complex pattern of variation among its members but is not separable into distinct subspecific groups of several peak variants). The complex is distinguished by a triangular leaf blade (two to three times as long as broad). The leaf blade may be plain mid-green throughout to adaxially dark green and abaxially rich purple, often adaxially with the major venation white to pale grey-green.

Distribution and ecology. In perhumid tropical forest and regrowth understorey, on boulders in forest and on exposed cliffs and ravines at low to medium elevation.
