Doona affinis (synonym Shorea affinis) is a species of flowering plant in the family Dipterocarpaceae. [3] It is a tree endemic to Sri Lanka, where it grows in the remaining lowland rain forests in the island's southwest, often in deep rich soils on hillsides. [1]
Dipterocarpaceae is a family of flowering plants with 22 genera and about 695 known species of mainly lowland tropical forest trees. Their distribution is pantropical, from northern South America to Africa, the Seychelles, India, Indochina, Indonesia, Malaysia and Philippines. The greatest diversity of Dipterocarpaceae occurs in Borneo.

Doona disticha is a species of flowering plant in the family Dipterocarpaceae. It is a small tree endemic to Sri Lanka. It is native to the remaining lowland rain forests of southwestern Sri Lanka. It is threatened by overharvesting for timber, and by habitat loss by clearance of forest land for tea plantations.

Doona gardneri is a species of flowering plant in the family Dipterocarpaceae. It is a tree endemic to Sri Lanka. It is commonly known as red doon in English and rath dun in Sinhalese. It is a large tree native to lower montane rain forest, where it prefers deep, well-drained soils. It grows in disjunct subpopulations at Ensalwatta, Adam's Peak, and Loolkandura at about 1,000 meters elevation.
Shorea lissophylla is a species of plant in the family Dipterocarpaceae. It is endemic to Sri Lanka.
Doona macrophylla, synonym Shorea megistophylla, is a species of flowering plant in the family Dipterocarpaceae. It is a tree endemic to Sri Lanka. It is an emergent tree which typically grows by rivers and streams in the remaining lowland wet evergreen rain forest of southwestern Sri Lanka.
Shorea oblongifolia is a species of plant in the family Dipterocarpaceae. It is endemic to Sri Lanka.
Doona ovalifolia is a species of flowering plant in the family Dipterocarpaceae. It is a tree endemic to Sri Lanka. It is known as pini-beraliya in Sinhala. It grows along shallow streams in the remaining lowland rain forests of southwestern Sri Lanka. The tree has been extirpated from its original collection locations of the 1860s. Populations were recently found at Ayagama (2020) and Kelinkanda (2023).

Shorea zeylanica is a species of flowering plant in the family Dipterocarpaceae. It is a tree endemic to Sri Lanka. It is a canopy tree in the remaining lowland evergreen rain forests of southwestern Sri Lanka, becoming an emergent tree at higher elevations.
The Sri Lanka lowland rain forests represents Sri Lanka's Tropical rainforests below 1,000 m (3,281 ft) in elevation in the southwestern part of the island. The year-around warm, wet climate together with thousands years of isolation from mainland India have resulted in the evolution of numerous plants and animal species that can only be found in rain forests in Sri Lanka. The thick forest canopy is made up of over 150 species of trees, some of the emergent layer reaching as high as 45 m (148 ft). The lowland rain forests accounts for 2.14 percent of Sri Lanka's land area. This ecoregion is the home of the jungle shrew, a small endemic mammal of Sri Lanka. Sri Lanka has the highest density of amphibian species worldwide. Many of these, including 250 species of tree frogs, live in these rain forests.
Shorea arsorianoi is a species of flowering plant in the family Dipterocarpaceae. It is a tree endemic to the Philippines,, where it is native to the provinces of Davao del Norte, Davao del Sur, and Surigao del Sur on the island of Mindanao. It is a large tree, from 30 to 50 meters in height and a trunk up to 100 cm in diameter at breast height. It grows in lowland rain forest.
