A. glaucifolia grows at higher altitudes (1,300–2,000 m (4,300–6,600 ft)), 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.
  • Alsophila borbonica (syn. Cyathea borbonica) is the only species with bipinnate fronds.[2][3]
