Trema is a genus of about 15 species of evergreen trees closely related to the hackberries (Celtis), occurring in subtropical and tropical regions of southern Asia, northern Australasia, Africa, South and Central America, and parts of North America. They are generally small trees, reaching 10–20 m (33–66 ft) tall.
Strobilanthes is a genus of about 350 species of flowering plants in the family Acanthaceae, mostly native to tropical Asia and Madagascar, but with a few species extending north into temperate regions of Asia. Many species are cultivated for their two-lipped, hooded flowers in shades of blue, pink, white and purple. Most are frost-tender and require protection in frost-prone areas.
Calamus is a genus of flowering plants in the palm family Arecaceae that are among several genera known as rattan palms. There are an estimated 400 species in this genus, all native to tropical and subtropical Asia, Africa, and Australia. They are dioecious, mostly leaf-climbing lianas with slender, reedy stems. To aid scrambling some species have evolved hooks on the underside of the midrib, or more commonly by modified "pinnae" or tendrils in the form of stout, backward-pointing spines. These stems may grow to lengths of 200 metres.
Aeschynanthus is a genus of about 150 species of evergreen subtropical and tropical plants in the family Gesneriaceae. They are usually trailing epiphytes with brightly colored flowers that are pollinated by sunbirds. The genus name comes from a contraction of aischuno and anthos (flower). The common name for some species is "lipstick plant", which comes from the appearance of the developing buds. A full list of the accepted species and their synonyms can be found in the Smithsonian Institution's World Checklist of Gesneriaceae.
Boehmeria is a genus of 47 species of flowering plants in the nettle family Urticaceae. Of the species, 33 are indigenous to the Old World and 14 to the New World; no species is indigenous to both the Old and New Worlds. The species include herbaceous perennials, shrubs and small trees. Although related to the similar-looking species of the stinging nettles of genus Urtica, species of Boehmeria do not have stinging hairs. Because of the similarity in appearance, some species are commonly called "false nettles".
Litsea is a genus of evergreen or deciduous trees or shrubs belonging to the laurel family, Lauraceae. The genus includes a large number of accepted species in tropical and subtropical areas of North America and Asia.
Licuala is a genus of palms, in the tribe Trachycarpeae, commonly found in tropical forests of southern China, Southeast Asia, the Himalayas, New Guinea and the western Pacific Ocean islands.
Chionanthus, common name: fringetrees, is a genus of about 150 species of flowering plants in the family Oleaceae.
Dischidia is a genus of plants in the family Apocynaceae. They are epiphytes native to tropical areas of China, India and most areas of Indo-China. Dischidia are closely aligned with the sister genus Hoya. Unlike Hoya, the genus Dischidia is poorly known and has not been studied as closely.
Laportea is a genus of plants in the family Urticaceae. They are herbaceous, either annual or perennial. Like many plants of the Urticaceae, they have stinging hairs. There are stinging and non-stinging hairs on the same plant. The genus was named after the French naturalist Francis de Laporte de Castelnau.
Polyalthia is a genus of flowering plants in the family Annonaceae. There are approximately 90 species distributed from Africa to Asia and the Pacific.
Xanthophyllum is a genus of about 109 species of trees and shrubs, of the plant family Polygalaceae;. The generic name is from the Greek meaning "yellow leaf", referring to how the leaves are often yellow when dry. In Borneo it is known as minyak berok in Malay or nyalin in the Iban language.
Argostemma is a genus of flowering plants in the family Rubiaceae. It can be found in (sub)tropical Asia and western and west-central tropical Africa.
Mussaenda is a genus of flowering plants in the family Rubiaceae. They are native to the African and Asian tropics and subtropics. Several species are cultivated as ornamental plants.
Poikilospermum is a genus of shrubs or tall woody climbers, consisting of at least 33 accepted species. The plants are found from India and China (Yunnan), the Sino-Himalayan region to Sulawesi and Jawa in Indonesia. Some of the plants are used by people.
Friesodielsia is a genus of flowering plants in the custard apple and soursop family Annonaceae, with all species found in the Old World, mostly in the tropics. A molecular study shows that Friesodielsia should be more narrowly circumscribed, with the only species remaining being the Asian ones, which can also be distinguished by their possession of globose or ellipsoid monocarps, and six petals per flower arranged in two whorls.
