Schizolaena isaloensis is a tree in the family Sarcolaenaceae. It is endemic to Madagascar. The specific epithet refers to Isalo National Park, near where the species was identified. [3]
Schizolaena isaloensis grows as a tree up to 10 metres (33 ft) tall. The bark is thick and spongy. Its subcoriaceous leaves are elliptic to ovate or obovate in shape and coloured dark green above and pale green below. They measure up to 4 cm (2 in) long. The inflorescences of one to three axes each bear one or two flowers each with three sepals and five white petals. A light green involucre hides the young fruit. [3] Specimen notes found "young growth or coppicing plants somewhat glabrous; mature plants tomentose". [4]
Schizolaena isaloensis is known only from the south central regions of Ihorombe and Atsimo-Andrefana, [2] specifically within [5] and just beyond the southern limit of Isalo National Park and near the RN7 road. [3] Its habitat is the central region's Tapia woodlands which are often severely degraded; the recorded specimens occurred in open grassland. [3]
Schizolaena isaloensis has been found in very low numbers – at most 50 mature individuals. The recorded specimens are outside any protected area. Fires have been the main threat, which mature trees can withstand but younger trees cannot. [3]
Isalo National Park is a National Park in the Ihorombe Region of Madagascar, in the southwestern corner of the Province of Fianarantsoa. The closest town is Ranohira, and the closest cities are Toliara and Ihosy. It is a sandstone landscape that has been dissected by wind and water erosion into rocky outcrops, plateaus, extensive plains and up to 200 m (660 ft) deep canyons. There are permanent rivers and streams as well as many seasonal watercourses. Elevation varies between 510 and 1,268 m.
Schizolaena is a genus of trees and shrubs in the family Sarcolaenaceae. They are endemic to Madagascar.
Uapaca bojeri, or tapia, is a tree species endemic to Madagascar. A characteristic element of the Madagascan flora, it occurs in the central highlands, where it dominates a type of sclerophyllous forest or woodland. Tapia forest has a high ecological value due to the fauna, flora, and funga it harbours, and is of economic interest to the local population, e.g. for collection of tapia fruits, firewood, mushrooms or wild silkworms, and hunting. Local impact through fire and cutting is seen as a form of sustainable use however tapia woodlands are now found only in scattered, isolated stands totaling at most 132,255 ha. Native woody vegetation of the central highlands is increasingly replaced by grasslands, primarily due to increased fire frequency as areas are burned annually.
