C. glauca grows at higher altitudes (1300-2000m) and it is one of three species of tree fern that are indigenous to Réunion island.

  • Cyathea excelsa, which also occurs in Mauritius, grows at slightly lower altitudes (200-1700m). Like C. glauca, its leaves are tripinnate, but the new fronds of Cyathea excelsa are scaleless; those of C. glauca have red-brown scales.
  • Cyathea borbonica var. borbonica is the only species with bipinnate fronds.[1][2]
