This type of forest although floristically rich is commercially very poor. It is inferior to wet evergreen forests of lower elevations. Although species like Calophyllum etc. are found here they are nanic and crooked with a spreading crown. The heights of the trees seldom exceed 20 m and are heavily festooned with mosses, lichens, aroids and ferns. At an elevation of 1200 to 100 m a transition may be found between this type of forest and the wet evergreen.
The principal species are Calophyllum polyanthum, Cinnamomum sulphuratum, Elaeocarpus munroii, Garcinia sp., Memeceylon sp., Syzygium sp. and members of lauraceae. A good number of them show affinity towards temperate flora.
