Kleinhovia hospita (guest tree syn. Kleinhovia serrata Blanco, Grewia meyeniana Walp.) is an evergreen, tropical tree native to Indonesia, Malaysia and other parts of tropical Asia. It is monotypic, being the only species in the genus Kleinhovia.
Kleinhovia hospita is used as a traditional medicine in parts of Malaya, Indonesia and Papua New Guinea to treat scabies. The bark and leaves used as hairwash for lice, while the juice of the leaves are used as an eyewash. Young leaves are eaten as a vegetable. Bast fibres are used for making ropes used for tying or for tethering livestock.
The wood of K. hospita shows a pinkish buff and is moderately fine in texture, soft, light, easy to season, work and finish. Its energy value is about 19000 kJ/kg. The leaves and bark contain cyanogenic compounds that are assumed to help to kill ectoparasites such as lice. Extracts of the leaves have shown anti-tumour activity against sarcoma in mice. A number of fatty acids with a cyclopropenylic ring (scopoletin, kaempferol, and quercetin) have been isolated from the leaves.
Kleinhovia hospita is used for ornamental purposes: the attractiveness of the pink panicles accounts for its spread as an ornamental.
