Habitat and related species
A. glaucifolia grows at higher altitudes (1300 - 2000 m), and it is one of three species of tree fern that are indigenous to Réunion island.
 * Alsophila celsa (syn. Cyathea excelsa) which also occurs in Mauritius, grows at slightly lower altitudes (200-1700m). Like A. glaucifolia, its leaves are tripinnate, but the new fronds of A. celsa are scaleless; those of A. glaucifolia have red-brown scales.
