Also called the Eastern Kingdom by artists, Indomalaya spans the entire Indian subcontinent and Southeast Asia to the plains of southern China, and across Indonesia to Sumatra, Java, Bali and Borneo, located east of the Wallace Line, is the country's border. the kingdom named after Alfred Russel Wallace that divided Indomalaya and Australasia. Indomalaya also includes the Philippines, the Taiwan Lowlands, and the Ryukyu Islands of Japan. Much of Indomalaya is primary forest consisting of tropical and subtropical forests, with tropical and subtropical forests common to most of India and part of India. "South East Asia. The rainforests of Indomalaya are highly variable and diverse, with economically important plants, especially in the Dipterocarpaceae and Fabaceae families.
Indian subcontinent
The geographical area of India covers most of India, Bangladesh, Nepal, Bhutan, Sri Lanka and eastern Pakistan. The Hindu Kush, Karakoram, Himalayan, and Patkai bioregions comprise the northwest, north, and northeast; These systems were formed by the collision of the mountain-drift region of India and Asia 45 years ago. The Hindu Kush, the Karakoram and the Himalayas form the biogeographic boundary between the extreme temperatures and the flora and fauna of the Indian subcontinent and the subtropical Palaearctic region. Indochina
The Indochina bioregion includes most of Southeast Asia, including Myanmar, Thailand, Laos, Vietnam, and Cambodia, as well as the rainforests of southern China.
Sunda Shelf in the Philippines
Malaysia is a botanical region that straddles the border between Indomalaya and Australasia. It includes the Malay Peninsula and the Western Indonesian Islands (known as Sundaland), the Philippines, the Eastern Indonesian Islands, and New Guinea. Although Malaysia has many similarities botanically, the eastern and western parts of the Wallace Line are very different in terms of fauna; Sundaland shares its fauna with the Asian mainland, while the terrestrial fauna of the islands east of the Wallace Line derives at least in part from species from Australia, such as mammals and ratites. News
The flora of Indomalaya combines elements from the ancient supercontinents of Laurasia and Gondwana. The white Gondwanan was originally introduced by India, which escaped from Gondwana around 90 MYA, carrying the plants and animals of Gondwana found in the north, including cichlid fish and the family Crypteroniaceae plants and possibly Dipterocarpaceae. India merged with Asia 30-45 MYA and changed species. Later, as Australia-New Guinea moved from the north, the collision of the Australian and Asian plates caused the rise of the Wallacea islands, separating them from each other by a narrow ridge, allowing the evolution of plants in central Indomalaya and Australasia. Asian rain forest trees, including dipterocarps, crossed Wallacea into New Guinea, and many Gondwanan tree families, including podocarps and araucarias, moved west from Australia-New Guinea to western Malaysia and the Southeast Asia.
A tree
The family Dipterocarpoideae includes plant species characteristic of the tropical and semi-arid forests of Indomalaya, as well as a variety of species in the rainforests of Borneo. Teak (Tectona) is a characteristic feature of the dry forests of Indomalaya, from India to Indochina, Malaysia and the Philippines. Pitcher plants (Nepenthes) are also characteristic of Indomalaya, and various species are found in Sumatra, Borneo and the Philippines. The rainforests of Indomalaya and Australasia inherit many genera of plants, which for millions of years managed to spread through the islands between Sundaland and New Guinea. The two plants originated far apart, and the fossil record shows that the Asian species spread to Australasia from 33 million years ago after Australasia moved north, and the expansion increased there 12 years ago after the two continents the body came close to their current position. The change is asymmetrical, more Indomalayan species spread in Australasia than Australasian species in Indomalaya.
