<i>Olea</i> Genus of flowering plants

Olea is a genus of about 40 species in the family Oleaceae, native to warm temperate and tropical regions of the Middle East, southern Europe, Africa, southern Asia, and Australasia. They are evergreen trees and shrubs, with small, opposite, entire leaves. The fruit is a drupe. Leaves of Olea contain trichosclereids.

<i>Arisaema</i> Genus of plants

Arisaema is a large and diverse genus of the flowering plant family Araceae. The largest concentration of species is in China and Japan, with other species native to other parts of southern Asia as well as eastern and central Africa, Mexico and eastern North America. Asiatic species are often called cobra lilies, while western species are often called jack-in-the-pulpit; both names refer to the distinctive appearance of the flower, which consists of an erect central spadix rising from a spathe.

<i>Adenophora</i> Genus of flowering plants

Adenophora is a genus of flowering plants in the family Campanulaceae, the bellflowers. Plants of this genus are known commonly as ladybells. Most are native to eastern Asia, with a few in Europe. Many are endemic to either China or Siberia.

<i>Maianthemum</i> Genus of flowering plants

Maianthemum includes the former genus Smilacina and is a genus of perennial herbaceous flowering plants with fleshy, persistent rhizomes. It is widespread across much of North America, Europe and Asia, and may be terrestrial, aquatic or epiphytic. It is characterized by simple, unbranched stems that are upright, leaning or hanging down and have 2–17 foliage leaves. Leaves are simple and may clasp the stem or be short-petiolate. The inflorescence is terminal and either a panicle or a raceme with few to many pedicelate flowers. Most species have 6 tepals and 6 stamens; a few have parts in 4s. Tepals are distinct in most species and all of similar size. Flowers are spreading, cup-shaped or bell-shaped and usually white, but lavender to red or green in some species. Fruits are rounded to lobed berries containing few to several seeds.

<i>Paris</i> (plant) Genus of flowering plants

Paris is a genus of flowering plants described by Linnaeus in 1753. It is widespread across Europe and Asia, with a center of diversity in China.

<i>Tacca</i> Genus of flowering plants

The genus Tacca, which includes the batflowers and arrowroot, consists of flowering plants in the order Dioscoreales, native to tropical regions of South America, Africa, Australia, Southeast Asia, and various Oceanic islands. In older texts, the genus was treated in its own family Taccaceae, but the 2003 APG II system incorporates it into the family Dioscoreaceae. The APG III and APG IV systems continue to include Tacca in Dioscoreaceae.

<i>Phoebe</i> (plant) Genus of flowering plants

Phoebe is a genus of evergreen trees and shrubs belonging to the Laurel family, Lauraceae. There are 75 accepted species in the genus, distributed in tropical and subtropical Asia and New Guinea. 35 species occur in China, of which 27 are endemic. The first description of the genus was of the type species P. lanceolata made in 1836 by Christian Gottfried Daniel Nees von Esenbeck in Systema Laurinarum, p. 98.

<i>Ephedra</i> (plant) Genus of gymnosperms in the family Ephedraceae

Ephedra is a genus of gymnosperm shrubs. The various species of Ephedra are widespread in many arid regions of the world, ranging across southwestern North America, southern Europe, northern Africa, southwest and central Asia, northern China and western South America. It is the only extant genus in its family, Ephedraceae, and order, Ephedrales, and one of the three living members of the division Gnetophyta alongside Gnetum and Welwitschia.

<i>Aletris</i> Genus of flowering plants

<i>Linnaea</i> Genus of flowering plants in the honeysuckle family Caprifoliaceae

Linnaea is a plant genus in the honeysuckle family Caprifoliaceae. Until 2013, the genus included a single species, Linnaea borealis. In 2013, on the basis of molecular phylogenetic evidence, the genus was expanded to include species formerly placed in Abelia, Diabelia, Dipelta, Kolkwitzia and Vesalea. However, this is rejected by the majority of subsequent scientific literature and flora.

<i>Anodendron</i> Genus of flowering plants
