Mangifera is a genus of flowering plants in the cashew family, Anacardiaceae. It contains 64 species, with the best-known being the common mango. The center of diversity of the genus is in the Malesian ecoregion of Southeast Asia, particularly in Sumatra, Borneo, and the Malay Peninsula. They are generally canopy trees in lowland rainforests, reaching a height of 30–40 m (98–131 ft).
Gaultheria is a genus of about 283 species of shrubs in the family Ericaceae. The name commemorates Jean François Gaultier of Quebec, an honour bestowed by the Scandinavian Pehr Kalm in 1748 and taken up by Carl Linnaeus in his Species Plantarum. These plants are native to Asia, Australasia and North and South America. In the past, the Southern Hemisphere species were often treated as the separate genus Pernettya, but no consistent reliable morphological or genetic differences support recognition of two genera, and they are now united in the single genus Gaultheria.
Ledum was a genus in the family Ericaceae, including eight species of evergreen shrub native to cool temperate and subarctic regions of the Northern Hemisphere and commonly known as Labrador tea. It is now recognised as a subsection of section Rhododendron, subgenus Rhododendron, of the genus Rhododendron.
Rhodora was a section of subgenus Pentanthera in the genus Rhododendron, that has since been discontinued.
Rhododendron subgenus Pentanthera was a subgenus of the genus Rhododendron. The common name azalea is applied to many of the species, and also to species in some other subgenera. In 2005 it was discontinued and its four sections moved or dismembered.
Rhododendron subgenus Rhododendron is a subgenus of the genus Rhododendron. With around 400 species, it is the largest of the eight subgenera containing nearly half of all known species of Rhododendron and all of the lepidote species.
Rhododendron subg. Hymenanthes is a subgenus of the genus Rhododendron, with a widespread distribution in the temperate Northern Hemisphere. The species are evergreen shrubs and small to medium-sized trees, with medium-sized to large leaves. The flowers are large, produced in terminal trusses of 5-40 together.
Rhododendron spinuliferum is a species of flowering plant in the family Ericaceae, native to Yunnan and Sichuan, China.
Rhododendron lochiae is a species of plant in the family Ericaceae, and is one of only two species of the genus Rhododendron that are native to Australia. It is found only in restricted areas of mountain–top cloud forest habitats within the Wet Tropics of Queensland World Heritage Site. The other species, Rhododendron viriosum, was only formally classified as a separate species in 2002.
Rhododendron section Tsutsusi was a subgenus of the genus Rhododendron, commonly referred to as the evergreen azaleas. In 2005 it was reduced to a section of subgenus Azaleastrum. Containing 80 - 117 species, it includes both deciduous and evergreen types and is distributed in Japan, China and northeastern Asia. They are of high cultural importance to the Japanese. Among the species in this genus lie the largest flowering azaleas.
Rhododendron beyerinckianum is a species of rhododendron endemic to New Guinea. It is found in the Indonesian portion of the island and western Papua New Guinea, extending as far east as Mount Victoria and Mount Dayman, where it grows at elevations of 1400–4000 meters. It is a shrub that grows to 5 m in height, with leathery leaves that are narrowly ovate, 6 x 3.5 cm in size. Flowers are tubular-funnel-shaped and usually dark red, but also white, yellow, greenish or pink.
Rhododendron subgenus Azaleastrum is a subgenus of the genus Rhododendron.
Rhododendron subg. Choniastrum is a subgenus of the genus Rhododendron, originally a section of subgenus Azaleastrum it was elevated to subgenus rank after cladistic analysis revealed that together with Rhododendron it formed a major clade, distinct from other sections of Azaleastrum.
Rhododendron subsection Brachycalyx is a subsection of the genus Rhododendron, in section Tsutsusi, subgenus Azaleastrum, consisting of fifteen species of azaleas from Asia.
Rhododendron subsection Tsutsusi is a subsection of the genus Rhododendron, in section Tsutsusi, subgenus Azaleastrum, consisting of 66 species of Azaleas.
Rhododendron javanicum is a rhododendron species native to Indonesia, Malaysia, and the Philippines. This evergreen shrub grows to 5 m (16 ft) with bright orange flowers in spring.
