The Subfamily Spiraeoideae is further organized into finer groupings including:


[ Back to top ]


Abutilon () is a large genus of approximately 150 species of broadleaf evergreens in the mallow family, Malvaceae. The genus includes annuals, perennials, shrubs, and small trees from 1?10 m tall, and is found in the tropical and subtropical regions of all continents. The leaves are alternate, unlobed or palmately lobed with 3-7 lobes. The flowers are conspicuous, with five petals, mostly red, pink, orange, yellow or white. [more]




Adenostoma is a genus of shrubs containing only two species: Adenostoma fasciculatum (Commonly known as Chamise), and Adenostoma sparsifolium (Red shank). Both are native to coastal California and Baja California, while A. fasciculatum is also native to California's Sierra Nevada mountains. [more]


Alliaria is a genus of flowering plants in the mustard family. [more]




Aronia, the chokeberries, are two to three species of deciduous shrubs in the family Rosaceae, native to eastern North America. They are most commonly found in wet woods and swamps. Chokeberries are cultivated as ornamental plants and also because they are very high in antioxidant pigment compounds, like anthocyanins. The name "chokeberry" comes from the astringency of the fruits, which are inedible when raw. The berries can be used to make wine, jam, syrup, juice, soft spreads, tea and tinctures. The fruits are eaten by birds, which then disperse the seeds in their droppings; birds do not taste astringency and feed on them freely. [more]


Astilbe () is a genus of 18 species of perennial, herbaceous flowering plants, within the family Saxifragaceae. Some species are commonly known as False Goat's Beard, and False Spirea. Astilbe species are native to Asia and North America. [more]

Bougainvillea () is a genus of flowering plants native to South America from Brazil west to Peru and south to southern Argentina (Chubut Province). Different authors accept between four and 18 species in the genus. The plant was first described by Philibert Commer?on, a French botanist accompanying French Navy admiral and explorer Louis Antoine de Bougainville during his voyage of circumnavigation, and first published for him by Antoine Laurent de Jussieu in 1789. It is possible that the plants were first discovered by Jeanne Bar?, Commer?on's lover and assistant whom he snuck on board (despite regulations) disguised as a man (and who thus became the first woman to circumnavigate the globe). [more]


Brahea is a of palms in the Arecaceae family. They are commonly referred to as Hesper Palms and are endemic to Mexico and Central America. All Hesper Palms have large, fan-shaped leaves. There are 11 species described in the genus as follows: [more]

Hosta (, syn.: Funkia) is a genus of about 23?45 species of lily-like plants in the family Asparagaceae, subfamily Agavoideae, native to northeast Asia. They have been placed in their own family, Hostaceae (or Funkiaceae); like many 'lilioid monocots', they were once classified in the Liliaceae. The scientific name is also used as the common name; in the past they were also sometimes called the Corfu Lily, the Day Lily, or the Plantain lily, but these terms are now obsolete. The name Hosta is in honor of the Austrian botanist Nicholas Thomas Host. The Japanese name Giboshi is also used in English to a small extent. The rejected generic name Funkia, also used as a common name, can be found in some older literature. [more]




Impatiens () is a genus of about 850?1,000 species of flowering plants, widely distributed throughout the Northern Hemisphere and tropics. Together with the puzzling Hydrocera triflora, this genus makes up the family Balsaminaceae. Such a situation is highly unusual, and phylogenetic studies might reveal that Impatiens needs to be split up; some of its species might be closer to Hydrocera than to their presumed congeners. [more]


A Genus in the Kingdom Animalia.[2] [more]

Photinia () is a genus of about 40?60 species of small trees and large shrubs in the Rosaceae family. As interpreted here, the natural range of these species is restricted to warm temperate Asia, from the Himalaya east to Japan and south to India and Thailand. They have, however, been widely cultivated throughout the world as ornamentals for their white flowers and red fruits. [more]


Pitavia is a genus of in family Rutaceae. It contains the following species (but this list may be incomplete): [more]


Prunus is a genus of trees and shrubs, including the plums, cherries, peaches, apricots and almonds. It is traditionally placed within the rose family Rosaceae as a subfamily, the Prunoideae (or Amygdaloideae), but sometimes placed in its own family, the Prunaceae (or Amygdalaceae). There are around 430 species of Prunus, spread throughout the northern temperate regions of the globe. [more]

Rubus is a genus of flowering plants in the family Rosaceae, subfamily Rosoideae. These plants have prickles like roses and are often called brambles; this name is most often used for the blackberry and similar fruits that are also of rambling habit, and not used for those like the raspberry that grow as upright canes. Their fruit, called bramble fruit, is an aggregate of drupelets. [more]


Sprekelia is a of about 1-2 of bulbous plants in the family Amaryllidaceae, or Alliaceae. They are native to Central America. Like, Hippeastrum, these plants were known as Amaryllis. The Sprekelia is sometimes called the "Aztec lily", although it is not a true lily. Sprekelia formosissima is common in cultivation, planted in warm climates or raised in pots in colder climates, or planted and lifted, much as gladiolus. Even when well grown, bulbs often don't bloom every year. In a grouping of a dozen or so bulbs, only two or three may bloom in any given year. [more]


Morphological characters and geographic distribution are the same as those of the family.[4] [more]

They are herbaceous perennial vines growing to around four metres tall, with a large, woody caudex. The leaves are arranged spirally on the stem, and are peltate, with the leaf petiole attached near the centre of the leaf. The name Stephania comes from the Greek, "a crown". This refers to the anthers being arranged in a crown like manner. [more]







Stewartia (sometimes spelled Stuartia) is a genus of 8-20 species of flowering plants in the family Theaceae, related to Camellia. Most of the species are native to eastern Asia in China, Japan, Korea, Laos, Myanmar, Thailand, and Vietnam, with two (S. malacodendron, S. ovata) in southeast North America, from Virginia and Kentucky south to Florida and Louisiana. [more]


Stromanthe is a genus of in family Marantaceae. It contains the following species (but this list may be incomplete): [more]


Stylidium (also known as triggerplants or trigger plants) is a genus of dicotyledonous plants that belong to the family Stylidiaceae. The genus name Stylidium is derived from the Greek st???? or stylos (column or pillar), which refers to the distinctive reproductive structure that its flowers possess. Pollination is achieved through the use of the sensitive "trigger", which comprises the male and female reproductive organs fused into a floral column that snaps forward quickly in response to touch, harmlessly covering the insect in pollen. Most of the approximately 300 species are only found in Australia, making it the fifth largest genus in that country. Triggerplants are considered to be protocarnivorous or carnivorous because the glandular trichomes that cover the scape and flower can trap, kill, and digest small insects with protease enzymes produced by the plant. [more]


Oreocereus is a of cacti (family Cactaceae), known only from high altitudes of the Andes. Its name was formed from Greek and means "mountain cereus". [more]








Swertia is a genus in the gentian family containing plants sometimes referred to as the felworts. Some species bear very showy purple and blue flowers. [more]












Taiwania (Taiwania cryptomerioides) is a large coniferous tree in the cypress family Cupressaceae, formerly listed in the segregate family Taxodiaceae. It is native to eastern Asia, growing in the mountains of central Taiwan, and locally in southwest China and adjoining Myanmar and northern Vietnam. It is endangered by illegal logging for its valuable wood in many areas. It is very likely that the range was more extensive in the past before extensive felling for the wood. [more]


Tamus is a genus of one or two species of flowering plants in the family Dioscoreaceae, native to Europe, northwestern Africa, and western Asia. The genus is now often included within the related genus Dioscorea, but is maintained as distinct by some authors. [more]








Tecomanthe is a genus of 5 species of tropical or subtropical forest lianes in the family Bignoniaceae. They have attractive trumpet-like flowers and glossy leaves. They are native to Australia, Indonesia, New Guinea, New Zealand, and the Solomon Islands. [more]




Tellima grandiflora (Fringecups, Bigflower Tellima) is a perennial of the family Saxifragaceae. It is a native of most forests in western North America. Frequently grown in gardens, it has escaped and become established in some other areas, e.g. Great Britain. The small green, white or purple flowers are born in spikes and the petals are deeply fringed. It is the only species in the genus Tellima. [more]


Tetracentron sinense is a flowering plant, the sole species in the genus Tetracentron. It is also often considered the sole species in the family Tetracentraceae, though some botanists include it in the family Trochodendraceae together with the very distinct genus Trochodendron. [more]






Thlaspi are a genus of herbs of temperate regions. The rare species T. perfoliatum occurs primarily in Oxfordshire, England and is protected under the UK Biodiversity Action Plan. [more]


Thujopsis (pronounced "Thuyopsis") is a conifer in the cypress family (Cupressaceae), the sole member of the genus being Thujopsis dolabrata. It is endemic to Japan, where it is named asunaro (????). It is similar to the closely related genus Thuja (Arborvitae), differing in the broader, thicker leaves and thick cones. Though some use false arborvitae, the species has never acquired a widely used English name, usually being known either by the Japanese name or by its genus name, Thujopsis; it is occasionally also compounded as Hiba Arborvitae due to its similarity to Thuja. [more]


Thunia is a of orchids (family Orchidaceae) and the only genus of the subtribe Thuniinae. The genus comprises 6 species, native to Southeast Asia. It is abbreviated Thu in trade journals. [more]




The Foamflowers (Tiarella) are a popular genus of wildflower and garden plants. They belong to the Saxifrage family (Saxifragaceae). Some species are: [more]




A Genus in the Kingdom Plantae. [more]




Zelkova is a genus of six species of deciduous trees in the elm family Ulmaceae, native to southern Europe, and southwest and eastern Asia. They vary in size from shrubs (Z. sicula) to large trees up to 35 m tall (Z. carpinifolia). The leaves are alternate, with serrated margins, and (unlike the related elms) a symmetrical base to the leaf blade. The fruit is a dry, nut-like drupe, produced singly in the leaf axils. [more]

At least 56 species and subspecies belong to the Genus Zelkova.

More info about the Genus Zelkova may be found here.
