Eleutherococcus is a genus of 38 species of thorny shrubs and trees in the family Araliaceae. They are native to eastern Asia, from southeast Siberia and Japan to the Philippines and Vietnam. 18 species come from China, from central to western parts. Perhaps the best known in the West is the species E. senticosus used as herbal medicine, and commonly known by such English names as Eleuthero or Siberian ginseng. In Traditional Chinese medicine, this is administered to increase energy, thus traditionally recognized to have attributes akin to true ginseng (Panax). This is also reflected in its

Nepenthes rajah is a carnivorous pitcher plant species of the family Nepenthaceae. It is endemic to Mount Kinabalu and neighbouring Mount Tambuyukon in Sabah, Malaysian Borneo. Nepenthes rajah grows exclusively on serpentine substrates, particularly in areas of seeping ground water where the soil is loose and permanently moist. The species has an altitudinal range of 1,500–2,650 m (4,920–8,690 ft) above sea level and is thus considered a highland or sub-alpine plant. Due to its localised distribution, N. rajah is classified as an endangered species by the IUCN and listed on CITES Appendix I.

The edible flower is the national flower of El Salvador locally called izote, and it is used extensively in Salvadoran cuisine.

Peraceae Klotzsch is a family of flowering plants in the eudicot order Malpighiales. The family was segregated from the Euphorbiaceae by Johann Friedrich Klotzsch in 1859, and its uniqueness was affirmed by the Royal Botanic Gardens, Kew's Euphorbiaceae expert, Airy Shaw. The family is accepted in APG IV (2016), but was not recognized in earlier Angiosperm Phylogeny Group III which considered that the recognition of the family may be necessary for a monophyletic Euphorbiaceae, but said that a formal recognition awaited additional molecular and morphological studies of the family. The family

Parthenium argentatum, commonly known as the guayule ( or , as in Spanish), is a perennial woody shrub in the family Asteraceae that is native to the rangeland area of the Chihuahuan Desert; including the southwestern United States and northern Mexico. It was first documented by J.M. Bigelow in 1852 through the Mexican Boundary Survey and was first described by Asa Gray. Natural rubber, ethanol, non-toxic adhesives, and other specialty chemicals can be extracted from guayule. An alternative source of latex that is hypoallergenic, unlike the normal Hevea rubber, can also be extracted. While

Sceptridium multifidum is a fern species in the Ophioglossaceae (Adder's tongue family), known by the common names leathery grapefern and leathery moonwort.

Thymelaea passerina, the spurge flax, sparrow weed, mezereon, or annual thymelaea, is a species of flowering plant in the family Thymelaeaceae. It is native to central and southern Europe, the Middle East, Central Asia, the western Himalayas, and Xinjiang in China, and it has been introduced to central North America, and to South Australia. An erect annual from 6 to 61 cm (2.5 to 24 in) tall, it is typically found in steppes, disturbed areas, and old fields.

Yucca baccata (datil yucca or banana yucca, also known as Spanish bayonet and broadleaf yucca) is a common species of yucca native to the deserts of the Southwestern United States and three states in Northern Mexico. The species gets its common name "banana yucca" from its banana-shaped fruit. The specific epithet baccata means 'with berries'. Banana yucca is closely related to the Yucca schidigera, the Mojave yucca, with which it is interspersed where their ranges overlap; hybrids between them occur.

Rodgersia is a genus of flowering plants in the Saxifragaceae family. Rodgersia are herbaceous perennials originating from east Asia.

Hedera colchica is a species of flowering plant in the family Araliaceae . It is native to the Middle East and commonly called Persian ivy or colchis ivy. It is an evergreen climbing plant, growing to 30 m high where suitable surfaces (trees, cliffs, walls) are available, and also growing as ground cover where there are no vertical surfaces. It climbs by means of aerial rootlets which cling to the substrate. In warm climates, it grows more rapidly and becomes established faster than other Hedera species.

It is known as "Chinese cucumber" and "Chinese snake gourd" in English.

Dracaena angolensis (synonym Sansevieria cylindrica), commonly known as African spear or the spear sansevieria, is a succulent plant native to Angola in Southern Africa. For years, it was placed within the genus Sansevieria (snake-plants), a specific name which is still used synonymously by some; in the 21st century, Sansevieria became part of Dracaena (dragon-trees), after improved testing methods, physical comparisons, and other analyses found sufficient commonalities between the two genera to warrant subsumption. The genus Dracaena is a part of the Asparagaceae (asparagus family)—i.e.,

Primula japonica, the Japanese primrose, Japanese cowslip, Queen of primroses, or valley red, is a species of flowering plant in the family Primulaceae, native to Japan. The common name Japanese primrose also applies to the related species Primula sieboldii. The plant prefers shady, damp, poorly drained conditions such as those found at the edge of streams and ponds. Numerous cultivars have been developed for garden use, of which 'Miller's Crimson' and 'Postford white' have won the Royal Horticultural Society's Award of Garden Merit.

Nepenthes veitchii (; after James Veitch, nurseryman of the Veitch Nurseries), or Veitch's pitcher-plant, is a Nepenthes species from the island of Borneo. The plant is widespread in north-western Borneo and can also be found in parts of Kalimantan. It grows in lowland Dipterocarp forest, typically near rivers, and on ridgetops in mossy forests, from 0 to 1,600 meters elevation. Nepenthes veitchii usually grows as an epiphyte, though the form from Bario seems to be strictly terrestrial and has not been observed to climb trees. Frederick William Burbidge described the growth habit of N.

Nepenthes lowii, commonly called Low's pitcher plant, is a tropical pitcher plant endemic to Borneo. It is named after Hugh Low, who discovered it on Mount Kinabalu. This species is perhaps the most unusual in the genus, being characterised by its strongly constricted upper pitchers, which bear a greatly reduced peristome and a reflexed lid with numerous bristles on its lower surface.
