Khat or qat (Catha edulis), also known as Bushman's tea, especially in South Africa, is a species of flowering plant in the family Celastraceae, and the sole species in genus Catha. It is a shrub or tree native to eastern and southern Africa, ranging from Ethiopia and South Sudan to Angola and the Cape Provinces of South Africa. It grows in montane riverine and evergreen forests from 1,100 to 2,400 metres elevation. It has a history of cultivation originating in the Harar region of Ethiopia, and it was subsequently introduced at different times to countries nearby in East Africa and South

Abies nordmanniana, the Nordmann fir or Caucasian fir, is a fir indigenous to the mountains south and east of the Black Sea, in Turkey, Georgia and the Russian Caucasus. It occurs at elevations of 900–2,200 m on mountains with precipitation of over 1,000 mm. The current distribution of the Nordmann fir is associated with the forest refugia that existed during the Ice Age at the eastern and southern Black Sea coast. In spite of currently suitable climate, the species is not found in areas of the Eastern Greater Caucasus, which are separated from the Black Sea Coast by more than 400–500 km.

Paulownia tomentosa, common names princess tree, empress tree, or foxglove-tree, is a deciduous hardwood tree in the family Paulowniaceae, native to central and eastern China and the Korean Peninsula. It is an extremely fast-growing tree with seeds that disperse readily and is considered an invasive exotic species in North America that has undergone naturalisation in large areas of the Eastern US, even though it might be able to successfully get established through seeds only under ideal conditions. P. tomentosa has also been introduced to Western and Central Europe, and is establishing

Glebionis coronaria, formerly called Chrysanthemum coronarium, is a species of flowering plant in the family Asteraceae. It is native to the Mediterranean region. It is cultivated and naturalized in East Asia and in scattered locations in North America. Glebionis coronaria is used as a leaf vegetable.

Glebionis coronaria has been hybridized with related Argyranthemum species to create cultivars of garden

Mitragyna speciosa is a tropical evergreen tree of the Rubiaceae family native to Southeast Asia. It is indigenous to Cambodia, Thailand, Indonesia, Malaysia, Myanmar, and Papua New Guinea, where its dark green, glossy leaves, known as kratom, have been used in herbal medicine since at least the 19th century. They have also historically been consumed via chewing, smoking, and as a tea. Kratom contains multiple alkaloids (primarily, mitragynine and to a lesser extent, 7-hydroxymitragynine) that bind to opioid receptors, most notably as partial μ-opioid agonists. Kratom can also be subjectively

Chamaecyparis, common names cypress or false cypress (to distinguish it from related cypresses), is a genus of conifers in the cypress family Cupressaceae, native to eastern Asia (Japan and Taiwan) and to the western and eastern margins of the United States.

They vary in size from shrubs (Z. sicula) to large trees up to 35 m (115 ft) tall (Z. carpinifolia). The bark is smooth, dark brown. Unlike elms, the branchlets are never corky or winged. The leaves are alternate, with serrated margins, and (unlike the related elms) a symmetrical base to the leaf blade. The leaves are in two distinct rows; they have pinnate venation and each vein extends to the leaf margin,

Putranjivaceae is a rosid family that is composed of 218 species in 2 genera of evergreen tropical trees that are found mainly in the Old World tropics, but with a few species in tropical America. Members of this family have distichous and coriaceous leaves, which, if fresh, typically have a radish-like or peppery taste. The flowers are fasciculate and usually small, and the fruits of these species are a single-seeded drupe crown by the persistent stigmas. This family has its origin in Africa and Malesia. It is the only family outside those in the order Brassicales that produces mustard oils.

It is now very common in northern Norway, where one of its names is Tromsø palm (after the city of Tromsø). The plant has also been spotted in Sweden. In Finland, it has been declared an invasive species. Persian hogweed is a polycarpic perennial, that is, a mature

The generic name comes from the ancient Greek pachys ('thick') and phyton ('plant'), a reference of the succulent nature of the leaves.

Xylopia aethiopica is an evergreen, aromatic tree, of the Annonaceae family that can grow up to 20m high. It is a native to the lowland rainforest and moist fringe forests in the savanna zones of Africa. The dried fruits of X. aethiopica (grains of Selim) are used as a spice and an herbal medicine.

Kniphofia uvaria is a species of flowering plant in the family Asphodelaceae, commonly known as tritomea, torch lily, or red hot poker, due to the shape and color of its inflorescence. The leaves are reminiscent of a lily, and the flowerhead can reach up to 1.5 m (5 ft) in height. There are many varieties of torch lily, and they bloom at different times during the growing season. The flowers are red, orange, and yellow.

Merremia is a genus of flowering plants in the morning glory family, Convolvulaceae. Members of the genus are commonly known as woodroses.

Bromheadia, commonly known as reed orchids, is a genus of about 29 species of orchids in the family Orchidaceae. They are evergreen terrestrial and epiphytic plants with unbranched stems, the leaves arranged in two rows along the flowering stem. The flowers appear in succession near the end of the flowering stem with the sepals and petals free from each other. The labellum is like a landing platform and has three lobes. They are native to areas from tropical Asia to northern Australia.

Ridolfia segetum, called false fennel, corn parsley, or false caraway, is an annual weed of the Mediterranean region. Its height is 40–100 centimetres (16–39 in). The stem is erect, striate, and branched. The glabrous leaves are finely divided several times with filiform leaflets. The upper leaves frequently reduced and the base of the petiole enlarged.

The essential oil contains the chemicals α-phellandrene, α-terpinolene,

Anogramma leptophylla, sometimes called Jersey fern, is a species of fern in the family Pteridaceae. It is found worldwide in temperate and subtropical regions. A rarity in the Pteridophyta, it is a fern whose sporophyte tends to have an annual life cycle. The gametophytes of this species have the ability to become dormant and wait as much as two and a half years until conditions are appropriate for the sporophyte stage of the life-cycle.

These plants grow mainly in the warmer regions of the Americas and West Indies. Over 150 species are native to Mexico. Some flourish in the cooler areas of the eastern United States. Two Mexican species have become a pest in parts of Australia and Taiwan. Ageratina used to belong to the genus Eupatorium, but it has been reclassified. The genus name Ageratina means "like Ageratum" and consists of Ageratum and -ina, the feminine form of the Latin adjectival suffix

It grows in arid and semi-arid conditions, throughout a range of cold desert, steppe, and mountain habitats in the Intermountain West of North America. Big sagebrush and other Artemisia shrubs are the dominant plant species across large portions of the Great Basin. Sagebrush provides food and habitat for a variety of species, such as sage grouse, pronghorn antelope, grey vireo, pygmy rabbit, and mule
