4. Asterella syngenesica ( Bory 1804: 95) Grolle & Onraedt (1974: 230)

Family:— Aytoniaceae

Distribution:— Mauritius and Réunion.

Habitat:— Shaded soil and rocks, terricolous to humo-terricolous on rocks, 270 - 2350 m, known from 18 localities in Réunion and from 48 records on the island

Threat:— Populations of this liverwort seem to be widely distributed on the island from low to upper land. It is possible that more investigations will increase the number of localities. As some populations are located closed to urban areas, the possibility that they could be affected in a close future can not be excluded. In Mauritius, the species is known only from two localities.

IUCN threat category:— NT

Specimens:— Cirque de Cilaos, Cirque de Salazie, Cirque de Mafate , Dos d’Ane, Heights of Basse Vallée , Makes, Plaine des Cafres , Piton de La Fournaise , Plaine des Palmistes , Takamaka, Valley of Langevin river ( Figure 3) .
