The genus Phylica of the Rhamnaceae family includes regarding 150 species. Most of them are African and nearly 140 species are especially endemic to the Cape Province in Africa (covering an area of ​​30,221,532 km2 including the islands,…) South (South is a cardinal point, opposite north.). They are shrubs or small trees.
Species that are not African or Malagasy occupy various islands in the Indian Ocean (The Indian Ocean covers an area of ​​75,000,000 km². It is limited to the north…) and the South Atlantic. Thus, the only ligneous plant (A ligneous plant is a plant which produces lignin, a molecule giving the plant its…) arborescent naturally present in the French Southern and Antarctic Lands is found on the island (An island is a stretch of land surrounded by water, whether this water is that of a watercourse, a…) Amsterdam (Indian Ocean) and belongs to the genus Phylica. Similarly in the Tristan da Cunha group (Atlantic Ocean), only two native tree species grow, including a Phylica. There are also Phylica in the Mascareignes (The Mascareignes are three islands in the south-west of the Indian Ocean located off the east coast…) (Réunion and Mauritius), and on the island of Sainte-Hélène.
This singularity (Generally speaking, the word singularity describes the singular character of something or…) has attracted the curiosity of researchers to the genus Phylica, who have sought to understand the relationships of the various isolated populations and the mechanisms of dispersion (Dispersion, in wave mechanics, is the phenomenon affecting a wave in a…). The most recent phylogenetic studies tend to show that all island species derive from the species (In the life sciences, the species (from the Latin species, “type”) having the largest area of ​​extension in Southern Africa (Phylica paniculata).
The populations of the mountains of Reunion Island (Reunion is a French island in the south-west of the Indian Ocean located…) and of Mauritius would form an endemic species of the Mascarenes (Phylica nitida). The bastard ambaville (The bastard ambaville (Phylica nitida) is a shrub of the Rhamnaceae family, endemic to…) (Phylica nitida) is a shrub of the Rhamnaceae family, present at altitude (The altitude is l vertical elevation of a place or an object in relation to a level…) in Reunion and Mauritius. It is one of the constituent ligneous plants in Reunion of the mountain maquis called branles or ericoid thickets present at altitude.
Those of Saint Helena would also be specific to the island (Phylica polifolia).
As for the Phylica of Amsterdam Island and those of Gough Island in the archipelago (An archipelago is a group of islands relatively close to each other. Proximity…) Tristan da Cunha, they would belong, despite their distance, to the same species (Phylica arborea). To explain this relationship, we very seriously hypothesize that the beaked albatross (A beak, in the strict sense, is an external anatomical structure that allows food intake and…) yellow (There are (at least) five definitions of yellow which designate more or less the same…) (Diomedea chlororhynchos), breeding on these two groups of islands, was the agent of transport (Transport is the fact of carrying something, or someone , from one place to another, the most…) seeds.
