Pringlea antiscorbutica, commonly known as Kerguelen cabbage, is a flowering plant and the sole member of the monotypic genus Pringlea in the family Brassicaceae. Its common name comes from the archipelago of its discovery, the Kerguelen Islands, and its generic name derives from Sir John Pringle, president of the Royal Society at the time of its discovery by Captain James Cook's Surgeon, William Anderson in 1776. Despite its appearance and edibility, it is not related to the common broadleaf plantain.

Cota tinctoria, the golden marguerite, yellow chamomile, or oxeye chamomile, is a species of perennial flowering plant in the sunflower family. Other common names include dyer's chamomile, Boston daisy, and Paris daisy. In horticulture this plant is still widely referred to by its synonym Anthemis tinctoria. It is a short-lived plant often treated as biennial, native to Europe, the Mediterranean and Western Asia and naturalized in scattered locations in North America. It has aromatic, bright green, feathery foliage. The serrate leaves are bi-pinnatifid (= finely divided) and downy beneath. It

Disocactus is a genus of epiphytic cacti in the tribe Hylocereeae found in Central America, the Caribbean and northern South America. It should not be confused with Discocactus, which is a different genus. Species of Disocactus grow in tropical regions either on trees as epiphytes or on rocks as lithophytes. They have two distinct growth habits. Species such as D. phyllanthoides have stems which are round at the base but then become flattened and leaflike. Many of the cultivated plants known as epiphyllum hybrids or just epiphyllums are derived from crosses between species of Disocactus

Botrychium matricariifolium (orth.var. B. matricariaefolium) is a species of fern in the Ophioglossaceae family. It is referred to by the common names chamomile grape-fern, daisyleaf grape-fern, and matricary grape-fern. It is native to Europe and parts of eastern North America, including eastern Canada and parts of the United States. This fleshy fern grows up to 30 centimeters tall. It produces dull green sterile leaf blades up to 10 centimeters long by 9 wide divided into a few pairs of segments. The fertile leaves are a bit longer and bear the spores.

Tabebuia rosea, also called pink poui, Sakura Malaysia and rosy trumpet tree, is a neotropical tree that grows up to 30 m (98 ft) and can reach a diameter at breast height of up to 100 cm (3 ft). The Spanish name roble de sabana, meaning "savannah oak", is widely used in Costa Rica, probably because it often remains in heavily deforested areas and because of the resemblance of its wood to that of oak trees. It is the national tree of El Salvador, where it is called maquilíshuat. Even though Tecoma trees are not originally native to Malaysia, they have adapted extremely well to the Southeast

Potamogeton friesii, known as flat-stalked pondweed, or Fries' pondweed, is an aquatic plant in the genus Potamogeton. It grows mainly in mesotrophic to eutrophic rivers, lakes, ponds and ditches, rarely in brackish water. It occurs in North America, Europe, western Asia and a few scattered locations elsewhere in Asia.

Microcachrys tetragona, known as creeping pine or creeping strawberry pine, is a species of dioecious conifer belonging to the podocarp family (Podocarpaceae). It is the sole species of the genus Microcachrys. The plant is endemic to western Tasmania, where it is a low shrub growing to 1 m tall at high altitudes. Its leaves are scale-like, arranged (unusually for the Podocarpaceae) in opposite decussate pairs, superficially resembling those of the unrelated Diselma archeri (Cupressaceae). It shares the common name Creeping pine with several other plants. Females produce tiny, red, edible

Leucobryum glaucum, commonly known as leucobryum moss or pincushion moss, is a species of haplolepideous mosses (Dicranidae) with a wide distribution in eastern North America and Europe. It inhabits temperate forests in the Northern Hemisphere, and its structure allows it to absorb metal ions. Leucobryum glaucum reproduces through Apical growth, Fragmentation, and a form of sexual reproduction called Oogamy. This process requires moist conditions as the sperm can only travel through water

Acer rufinerve, the grey-budded snake-bark-maple, redvein maple or Honshū maple (Japanese: ウリハダカエデ urihadakaede, "melon-skin maple"), is a species of tree in the snakebark maple group, related to Acer capillipes (Kyushu maple). It is native to mountain forests of Japan, on Honshū, Kyūshū and Shikoku. The Latin and English names rufinerve and "redvein" refer to the reddish down on the veins.

It is a slow-growing, spreading evergreen perennial growing to 10 cm (4 in) tall by 60 cm (24 in) broad, with alternate, simple, glossy leaves, and creeping stems. The leaves may yellow in direct sunlight or in winter. When growing in a spreading mass of many plants, a dense cover is formed. The flowers are white, borne above the foliage. In temperate Northern Hemisphere sites

Iochroma is a genus of about 34 species of shrubs and small trees belonging to the nightshade family Solanaceae. Species are native from Mexico to south Brazil. They are found in the forests of Mexico and South America. Their hummingbird-pollinated flowers are tubular or trumpet-shaped, and may be blue, purple, red, yellow, or white, becoming pulpy berries. The cupular (cup-shaped) calyx is inflated in some species. The leaves are alternate, simple, and entire. Iochromas are cultivated as flowering ornamentals and in cooler zones (zones 7–8/9) make useful patio shrubs for summer display or

Acer crataegifolium (hawthorn-leaf maple or uri maple; Japanese: ウリカエデ urikaede, "melon maple"), is a species of maple in the snakebark maple group, native to mountains forests of central and southern Japan, on Honshū (Fukushima southward), Kyūshū, and Shikoku.

Hamamelis japonica, Japanese witch-hazel, is a species of flowering plant in the family Hamamelidaceae, native to Japan but widely cultivated in temperate situations elsewhere. A horizontally spreading, hardy deciduous shrub or small tree, it is notable for the slightly fragrant yellow blooms which clothe its naked branches in the depths of winter through to early spring (usually in January and February). The green leaves follow, and in favourable locations they turn yellow before dropping in autumn. H. japonica is one parent of the hybrid Hamamelis × intermedia, an extremely popular and

Eupomatia is a genus of three species of plants in the ancient family Eupomatiaceae, and is the sole genus in the family. Eupomatiaceae is recognised by most taxonomists and classified in the plant order Magnoliales. The three described species are shrubs or small trees, native to the rainforests and humid eucalypt forests of eastern Australia and New Guinea. The type species Eupomatia laurina was described in 1814 by Robert Brown.
