Rhododendron is a very large genus of about 1,024 species of woody plants and in the heath family (Ericaceae). They can be either evergreen or deciduous. Most species are native to eastern Asia and the Himalayan region, but smaller numbers occur elsewhere in Asia, and in North America, Europe and Australia.
Syringa is a genus of 12 currently recognized species of flowering woody plants in the olive family or Oleaceae called lilacs. These lilacs are native to woodland and scrub from southeastern Europe to eastern Asia, and widely and commonly cultivated in temperate areas elsewhere.
Bulbophyllum is a genus of mostly epiphytic and lithophytic orchids in the family Orchidaceae. It is the largest genus in the orchid family and one of the largest genera of flowering plants with more than 2,000 species, exceeded in number only by Astragalus. These orchids are found in diverse habitats throughout most of the warmer parts of the world including Africa, southern Asia, Latin America, the West Indies, and various islands in the Indian and Pacific Oceans. Orchids in this genus have thread-like or fibrous roots that creep over the surface of trees or rocks or hang from branches. The stem is divided into a rhizome and a pseudobulb, a feature that distinguished this genus from Dendrobium. There is usually only a single leaf at the top of the pseudobulb and from one to many flowers are arranged along an unbranched flowering stem that arises from the base of the pseudobulb. Several attempts have been made to separate Bulbophyllum into smaller genera, but most have not been accepted by the World Checklist of Selected Plant Families.
Ulex is a genus of flowering plants in the family Fabaceae. The genus comprises about 20 species of thorny evergreen shrubs in the subfamily Faboideae of the pea family Fabaceae. The species are native to parts of western Europe and northwest Africa, with the majority of species in Iberia.
Gesneriaceae, the gesneriad family, is a family of flowering plants consisting of about 152 genera and ca. 3,540 species in the tropics and subtropics of the Old World and the New World, with a very small number extending to temperate areas. Many species have colorful and showy flowers and are cultivated as ornamental plants.
Bougainvillea is a genus of thorny ornamental vines, bushes, and trees belonging to the four o' clock family, Nyctaginaceae. They are native to Brazil, Bolivia, Paraguay, Peru, and Argentina. There are between 4 and 22 species in the genus. The inflorescence consists of large colourful sepal-like bracts which surround three simple waxy flowers, gaining popularity for the plant as an ornamental. The plant is named after explorer Louis Antoine de Bougainville (1729-1811), after it was documented on one of his expeditions.
Rebutia is a genus of flowering plants in the family Cactaceae, native to Bolivia and Argentina. The limits of the genus have varied widely, depending on whether genera such as Aylostera and Weingartia are included or treated separately. As of December 2024, Plants of the World Online accepted only three species of Rebutia. A very large number of plants that have been treated in cultivation as species of Rebutia are now generally regarded as varieties, forms or synonyms of a much smaller number of species, or have been transferred to other genera. Plants treated as Rebutia are generally small, colorful cacti, globular in form, which freely produce flowers that are relatively large in relation to the body. They have no distinctive ribs, but do have regularly arranged small tubercles. They are considered fairly easy to grow and they may produce large quantities of seeds that germinate freely around the parent plant.
Beaucarnea is a genus of flowering plants native to Mexico and Central America. In the APG III classification system, it is placed in the family Asparagaceae, subfamily Nolinoideae. Beaucarnea is sometimes treated as a synonym of the genus Nolina, with the species being then transferred to that genus. However, recent research shows that Beaucarnea should be treated as an independent genus.
Echinacea purpurea, the eastern purple coneflower, purple coneflower, hedgehog coneflower, or Echinacea, is a North American species of flowering plant in the family Asteraceae. It is native to parts of eastern North America and present to some extent in the wild in much of the eastern, southeastern and midwestern United States, as well as in the Canadian Province of Ontario. It is most common in the Ozarks, the Mississippi Valley, and the Ohio Valley. Its habitats include dry open woods, prairies, and barrens.
The Datiscaceae are a family of dicotyledonous plants, containing two species of the genus Datisca. Two other genera, Octomeles and Tetrameles, are now classified in the family Tetramelaceae.
Trichocereinae is a subtribe of cactus that are particular to South America. There are 28 recognized genera in this subtribe.
Goodenia is a genus of about two hundred species of flowering plants in the family Goodeniaceae. Plants in this genus are herbs or shrubs, mostly endemic to Australia. The leaves are variably-shaped, the flowers arranged in small groups, with three or five sepals, the corolla bilaterally symmetrical and either fan-shaped with two "lips" or tube-shaped. The petals are usually yellow to white, the stamens free from each other and the fruit a capsule.
Salvia is the largest genus of plants in the sage family Lamiaceae, with nearly 1,000 species of shrubs, herbaceous perennials, and annuals. Within the Lamiaceae, Salvia is part of the tribe Mentheae within the subfamily Nepetoideae. One of several genera, commonly referred to as sage, it includes two widely used herbs, Salvia officinalis and Salvia rosmarinus.
Nothorites is a monotypic genus in the macadamia family Proteaceae. The sole species, Nothorites megacarpus, is endemic to the wet tropics rain forests of northeastern Queensland, Australia.
Pygmaeocereus bieblii, synonym Haageocereus bieblii, is a species of cactus from Peru.
Pygmaeocereus bylesianus, synonym Haageocereus bylesianus, is a critically endangered species of cactus from Peru.
Hypericum formosissimum is a species of flowering plant in the St John's wort family Hypericaceae. Found in the cracks of limestone rocks, it is a small perennial herb that grows in a pillow-like shape, has yellow flower petals, and blooms in the late summer. The plant is rare and has a limited habitat in Turkey, Armenia, and Azerbaijan. It is threatened by rock collapses, urbanization, and road construction; it is not protected by conservation efforts.
Hypericum huber-morathii is a species of flowering plant in the St John's wort family Hypericaceae. It is a small perennial herb with few stems. It has narrow and brittle stems, thick leaves, flowers in clusters of varying numbers, small yellow petals, around twenty stamens, and three styles. H. huber-morathii is closely related to H. minutum and H. sechmenii, and also shares characteristics with H. lanuginosum. The plant is endemic to Turkey, and is found among limestone rocks in a limited region of southwestern Anatolia. Originally excluded from a comprehensive monograph of Hypericum, the species' placement within the genus is unclear. It has been placed in both section Adenosepalum and section Origanifolium.
Hypericum minutum is a species of flowering plant in the St John's wort family Hypericaceae. It is a small perennial herb that grows in tufts. It has slender and brittle stems, flowers in clusters of one to three, yellow petals with black and amber glands, few stamens, and a seed capsule with narrow grooves. H. minutum is closely related to H. huber-morathii and H. sechmenii and resembles a smaller form of the latter plant. The plant is endemic to Turkey, and is found among limestone rocks in a limited region of southwestern Anatolia. Originally excluded from a comprehensive monograph of Hypericum, the species' placement within the genus is unclear. It has been placed in both section Adenosepalum and section Origanifolium.
Hypericum decaisneanum is a species of flowering plant in the St John's wort family Hypericaceae. Named for French botanist Joseph Decaisne, it is a small perennial herb that grows mostly upright. It has thick, papery leaves and up to twenty flowers with bright yellow petals. Endemic to the Jebel al Akhdar province of Libya, H. decaisneanum is found in the cracks of limestone rocks on steep escarpments. It is a member of numerous plant communities and associations of chasmophytes, of which it is sometimes a key species. First described in 1899, the species was originally placed in section Taeniocarpium of the genus Hypericum, but more recently it has been considered a member of section Adenosepalum.
