Pyrus pyrifolia is a species of pear tree native to southern China and northern Indochina that has been introduced to Korea, Japan and other parts of the world. The tree's edible fruit is known by many names, including Asian pear, Persian pear, Japanese pear, Chinese pear, Korean pear, Taiwanese pear, apple pear, zodiac pear, three-halves pear, papple, naspati, bata kisbis, Fefeta grained pear and sand pear. Along with cultivars of P. × bretschneideri and Pyrus ussuriensis, the fruit is also called the nashi pear. Cultivars derived from Pyrus pyrifolia are grown throughout East Asia, and in

The Polyporales are an order of about 1,800 species of fungi in the division Basidiomycota. The order includes some (but not all) polypores as well as many corticioid fungi and a few agarics (mainly in the genus Lentinus). Many species within the order are saprotrophic, most of them wood-rotters. Some genera, such as Ganoderma and Fomes, contain species that attack living tissues and then continue to degrade the wood of their dead hosts. Those of economic importance include several important pathogens of trees and a few species that cause damage by rotting structural timber. Some of the

Serenoa repens, commonly known as saw palmetto, is a small palm, growing to a maximum height around 200–300 cm (6.6–9.8 ft).

Circaeasteraceae is a family of two species of herbaceous plants native to China and the Himalayas. The family has been recognized by many taxonomists. The APG II system (2003; unchanged from the APG system of 1998), recognizes it and places it in the order Ranunculales in the clade eudicots. It treats the family to consist of two genera each with a single species, Circaeaster agrestis and Kingdonia uniflora, but allows the option of segregating the latter species as family Kingdoniaceae. The APG III system of 2009 also recognizes the two species but no longer allows the optional segregation

Carpobrotus edulis is a creeping plant with succulent leaves in the genus Carpobrotus, native to South Africa. Its common names include hottentot-fig, sour fig, ice plant, highway ice plant, or vygie.

The Cantharellales are an order of fungi in the class Agaricomycetes. The order includes not only the chanterelles (Cantharellaceae), but also some of the tooth fungi (Hydnaceae), clavarioid fungi (Aphelariaceae and Clavulinaceae), and corticioid fungi (Botryobasidiaceae). Species within the order are variously ectomycorrhizal, saprotrophic, associated with orchids, or facultative plant pathogens. Those of economic importance include edible and commercially collected Cantharellus, Craterellus, and Hydnum species as well as crop pathogens in the genera Ceratobasidium and

Cupressus dupreziana, the Saharan cypress, or tarout, is a very rare coniferous tree native to the Tassili n'Ajjer mountains in the central Sahara desert, southeast Algeria, where it forms a unique population of trees hundreds of kilometres from any other trees. There are only 233 specimens of this endangered species, the largest about 22 m tall. The majority are estimated to be over 2000 years old, with very little regeneration due to the increasing desertification of the Sahara. Rainfall totals in the area are estimated to be about 30 mm annually. The largest one is named Tin-Balalan is

Faucaria is a genus of around 8 species of succulent subtropical flowering plants of the family Aizoaceae. The name comes from the Latin word fauces (“animal mouth”) because of the appearance of "teeth" on the leaves. Faucaria species are native to the Cape Province of South Africa and the Karoo Desert.

Drosera regia, commonly known as the king sundew, is a carnivorous plant in the sundew genus Drosera that is endemic to a single valley in South Africa. Individual leaves can reach 70 cm (28 in) in length. It has many unusual relict characteristics not found in most other Drosera species, including woody rhizomes, operculate pollen, and the lack of circinate vernation in scape growth. All of these factors, combined with molecular data from phylogenetic analysis, contribute to the evidence that D. regia possesses some of the most ancient characteristics within the genus. Some of these are

The Leyland cypress, Cupressus × leylandii, × Cuprocyparis leylandii or × Cupressocyparis leylandii, often referred to simply as leylandii, is a fast-growing coniferous evergreen tree much used in horticulture, primarily for hedges and screens. Even on sites of relatively poor culture, plants have been known to grow to heights of 15 metres (49 ft) in 16 years. Their rapid, thick growth means they are sometimes used to achieve privacy, but such use can result in disputes with neighbours whose own property becomes overshadowed. The tree is a hybrid of Monterey cypress (Cupressus macrocarpa) and

Primula florindae, the Tibetan cowslip or giant cowslip, is a species of flowering plant in the family Primulaceae. It is native to southeastern Tibet, where it grows in huge numbers close to rivers such as the Tsangpo. It is a substantial herbaceous perennial growing to 120 cm (47 in) tall by 90 cm (35 in) wide. In summer the flower stalks rise from basal rosettes of 5–20 cm (2–8 in) long leaves. They bear clusters of 20–40 yellow, pendent, bell-like, delicately scented flowers with a mealy white bloom. The plant was first collected for western horticulture in 1924 by the British botanist

Aloinopsis is a genus of ice plants native to the Cape Provinces of South Africa.

Salvia jurisicii, commonly known as Jurisic sage and Yugoslavian cut leaf sage or locally as Ovche Pole sage, is a hardy herbaceous perennial endemic to the steppe-like region in central North Macedonia. Together with other rare species, Salvia jurisicii is a key component of the “Macedonian steppe” ecotype. Mainly due to agricultural activity, this species is considered critically endangered in its native habitat.

Dinteranthus is a genus of plants in the family Aizoaceae. It occurs in the arid northwestern parts of the Northern Cape Province, South Africa and the south-eastern parts of Namibia.

Titanopsis is a genus of about four species of succulent plants of the family Aizoaceae, indigenous to the arid regions of South Africa and Namibia. The name Titanopsis is derived from the Greek (god), Titan, the sun, and opsis, appearance, from the sun-like appearance of the flower.

Scilla mischtschenkoana, the Mishchenko or Misczenko squill, early squill or white squill, is a perennial plant that is native to the South Caucasus and northern Iran. Each plant grows from a small bulb, with 2-3 strap shaped leaves and pale blue flowers with darker veins, blooming in early spring or late winter. Plants reach 5 to 15 cm (2.0 to 5.9 in) high and approximately 5 cm (2.0 in) wide. S. mischtschenkoana and the cultivar 'Tubergeniana' have gained the Royal Horticultural Society's Award of Garden Merit.

Frithia pulchra, the fairy elephant's feet, is a species of flowering plant in the fig‑marigold family Aizoaceae, endemic to Gauteng Province, South Africa (where it is classified as "Vulnerable" by the IUCN Red List). Its natural habitat is temperate grassland with high summer rainfall. A tiny stemless succulent growing to just 10 cm (3.9 in) tall and 20 cm (7.9 in) broad, it has bulbous oblong leaves with leaf windows at the tip; and magenta and white daisy-like flowers in summer. During periods of drought it has the ability to shrink beneath the soil surface, thus avoiding excessive

Eucalyptus baxteri, commonly known as brown stringybark, is a medium-sized tree that is endemic to the south-east of mainland Australia. It has rough, stringy bark to the thinnest branches, lance-shaped or curved adult leaves, green to yellow flower buds in groups of between nine and fifteen, and cup-shaped or hemispherical fruit.

Encephalartos transvenosus is a palm-like cycad in the family Zamiaceae, with a localized distribution in Limpopo, South Africa. Its common names, Modjadji's cycad or Modjadji's palm, allude to the female dynasty of the Lobedu people, the Rain Queens, whose hereditary name is Modjadji. The queen resides near a valley (of late a nature reserve) which is densely forested with these cycads, which they protected and hold sacred. The species name transvenosus refers to the fine network of veins between the main veins. These can be seen when the leaf is held up to the light.
