Genera

[ Back to top ]

Amischotolype

Herbs perennial. Stems erect, sometimes procumbent in basal part. Rhizomes long. Leaves alternate. Inflorescences borne at each node of middle part of stem, shortly pedunculate, penetrating leaf sheaths, each consisting of several cymes, usually capitate and sessile, sometimes corymbose or paniculate. Flowers nearly actinomorphic. Sepals free, carinate, herbaceous. Petals free, purplish, oblong or obovate-orbicular. Stamens 6, all fertile, subequal; filaments torulose villous; anther locules parallel, ovoid, longitudinally dehiscent. Ovary 3-loculed; ovules 2 per locule, sometimes 1 in posterior locule. Capsule 3-valved, globose or ovoid, trigonous. Seeds (1 or) 2 per valve, cylindric, trigonous, rugose, reticulate; hilum linear.[1] [more]

Blechnum

Blechnum (hard fern) is a genus of between 150?220 species of ferns with a cosmopolitan distribution, in the family Blechnaceae in the in the eupolypods II clade of the order Polypodiales. By far the greatest species diversity is in tropical regions of the Southern Hemisphere, with only a few species reaching cool temperate latitudes in the Southern Hemisphere (notably B. penna-marina, south to Cape Horn, Chile, the southernmost fern in the world) and Northern Hemisphere (notably B. spicant, north to Iceland and northern Norway). [more]

Callisia

Herbs, perennial or rarely annual. Roots thin, rarely tuberous. Leaves spirally arranged or 2-ranked; blade sessile. Inflorescences terminal and/or axillary, cyme pairs (often aggregated into larger spikelike or paniclelike units), cymes sessile, umbel-like, contracted, subtended by bracts; bracts inconspicuous, less than 1 cm; spathaceous bracts absent; bracteoles persistent. Flowers bisexual (bisexual and pistillate in C. repens), radially symmetric; pedicels very short or well developed; sepals distinct, subequal; petals distinct, white or pink to rose [rarely blue], equal, not clawed; stamens 6 or 0--3, all fertile, equal; filaments glabrous or bearded; ovary 2--3-locular, ovules [1--]2 per locule, 1-seriate. Capsules 2--3-valved, 2--3-locular. Seeds [1-]2 per locule; hilum punctiform; embryotega abaxial. x = 6--8.[2] [more]

Coleonema

Coleonema is a genus of flowering plants in the family Rutaceae. The eight known species are all from the western Cape Province of South Africa. In Australia, where they are cultivated as garden ornamentals, they are often incorrectly referred to as Diosma. [more]

Coleotrype

Cyanotis

Cyanotis (syn. Tonningia) is a genus of perennial plants in the family Commelinaceae. [1] [more]

Dichorisandra

Dichorisandra is a genus in the family Commelinaceae. [more]

Gibasis

Herbs, perennial or annual. Roots fibrous [tuberous]. Leaves 2-ranked [spirally arranged]; blade sessile. Inflorescences terminal and sometimes axillary, pairs or umbels of cymes, cymes pedunculate, axis sharply angled at junction with peduncle; spathaceous bract absent; bracteoles persistent. Flowers bisexual, radially symmetric; pedicels well developed; sepals distinct, subequal; petals distinct, white [to pink or blue], equal; stamens 6, all fertile, equal; filaments bearded; ovary 3-locular, ovules 2 per locule, 1-seriate.

Hosta

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]

Palisota

Palisota is a genus of in family Commelinaceae. [more]

Rhoeo

Inflorescence borne opposite leaf and exserted from mouth of leaf sheath, but not penetrating sheath, a long pedunculate panicle of numerous cincinni; basal cincinnus with a leaflike involucral bract at base, with bisexual flowers, others without involucral bracts, with only male flowers. Flowers actinomorphic. Sepals free, boat-shaped, herbaceous, galeate at apex. Petals free, purple or white, broadly linear or oblanceolate. Stamens 6, all fertile, equal; filaments lanate; anther locules parallel, ellipsoid, longitudinally dehiscent. Ovary 3-loculed; ovules 8 per locule. Capsule 3-valved, ovoid, trigonous; seeds 4--8 per valve, polygonal, reticulate; hilum linear.[4] [more]

Inflorescences borne at each node, opposite leaves, emerging from mouth of leaf sheath, each a large panicle of numerous cincinni; cincinni each subtended by an involucral bract; bracts similar to leaves, becoming smaller toward apex of cincinnus. Flowers actinomorphic, those of basal cincinnus bisexual, others male or bisexual. Sepals free, boat-shaped, galeate at apex. Petals free, linear-spatulate, white. Stamens 6, all fertile, equal; filaments densely torulose-hairy; anther locules parallel, ellipsoid, longitudinally dehiscent. Ovary 3-loculed; ovules 2 per locule.

Tradescantia

Spiderwort (Tradescantia) is a genus of an estimated 71 species of perennial plants in the family Commelinaceae, native to the New World from southern Canada south to northern Argentina. They are weakly upright to scrambling plants, growing to 30-60 cm tall, and are commonly found individually or in clumps in wooded areas and fields. The leaves are long, thin and bladelike to lanceolate, from 3-45 cm long. The flowers are white, pink or purple but most commonly bright blue, with three petals and six yellow anthers. The sap is mucilaginous and clear. A number of the species flower in the morning and when the sun shines on the flowers in the afternoon they close up, but the flowers can remain open on cloudy days until evening. [more]

Trias

Trias is a board game authored by Ralf Lehmkuhl. It is distributed by Rio Grande Games, Tilsit Editions and Gecko Games. [more]

Trichodiadema

Trichomanes

Trichomanes is a large genus of ferns in the family Hymenophyllaceae, termed bristle ferns. Some botanists place it in its own family, Trichomanaceae. All ferns in the hymenophylloid clade are filmy ferns, with leaf tissue typically 2 cells thick. This thinness generally necessitates a permanently humid habitat, and makes the fronds somewhat translucent. [more]

Trichopetalum

Trichopilia

Trichotosia

Tricyrtis

Tricyrtis is a genus of the botanical family Liliaceae, known in English as Toad lilies. Its native range is from the Himalayas to eastern Asia, including China, Japan, Philippines and Formosa. [more]

Triglochin

Arrowgrass is the common name for members of the genus Triglochin. The genus belongs to the family Juncaginaceae and counts about a dozen-and-a-half members. North America has four (or five) species, two of which can also be found in the British Isles (and Europe): Triglochin palustris, marsh arrowgrass and Triglochin maritimum, sea arrowgrass. Australia has many more. [more]

Trigonidium

Trigonobalanus

Trigonobalanus is a genus of three species of evergreen in the family Fagaceae, related to beeches and chestnuts. The species are widely scattered, with one in northern South America and two in southeast Asia; some botanists treat the three species in separate genera. The three species, with their authors, major synonyms and distribution, are: [more]

Triolena

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

Tripogandra

[more]

Tristania

Tristania is a genus in the myrtle family Myrtaceae, native to New South Wales, Australia, closely related to Callistemon. The genus had a number of species, but some have been reclassified as Lophostemon and Tristaniopsis. [more]

Tritonia

Tritonia refers to a genus. The name derives from the god Triton. It may refer to: [more]

Trochetiopsis

The flowering plant genus Trochetiopsis consists of two extant and one extinct species endemic to the island of Saint Helena (South Atlantic Ocean). They were formerly placed in the family Sterculiaceae, but this is included in the expanded Malvaceae in the APG and most subsequent systematics. [more]

Tsuga

Tsuga (, from Japanese: ? (??), the name of Tsuga sieboldii) is a genus of conifers in the family Pinaceae. The common name hemlock is derived from a perceived similarity in the smell of its crushed foliage to that of the unrelated plant poison hemlock. [more]

At least 153 species and subspecies belong to the Genus Tsuga.
