Alsophila glaucifolia, synonym Cyathea glauca,[1] is a species of tree fern endemic to Réunion. Little is known about this species.
Habitat and related species
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]
-
The fronds are tripinnate (branching to three levels). -
Growing under Acacia heterophylla in the forest of Bélouve, Réunion -
Detail of trunk and insertion of fronds. New growth is covered in red-brown scales. This serves to distinguish the species from the alien, non-indigenous Sphaeropteris cooperi (syn. Cyathea cooperi), which has red and white scales on its new growth. -
The alien Sphaeropteris cooperi can be distinguished from A. glaucifolia by the red and white scales on its new fronds.
