The plant is cultivated for its fruit extract containing mogrosides. Mogroside extract has been used as a low-calorie sugar substitute for drinks and in traditional Chinese medicine. One mogroside, mogroside V, creates a sweetness sensation 250 times stronger than sucrose.

The red flowers typically have a diameter of 50–90 cm (19+1⁄2–35+1⁄2 in) and smell awfully of rotten meat to attract flies for pollination. This species has some claim to being the world's largest flower, for although the average size of R. arnoldii is

Halophytum ameghinoi is a species of herbaceous plant endemic to Patagonia. It is the only species in the genus Halophytum. It is a succulent annual plant, with simple, fleshy, alternate leaves. The plants are monoecious, with solitary female flowers and inflorescences of male flowers on the same plant . Halophytum has sometimes been placed in its own family, Halophytaceae. For instance, the 2009 APG III system and the 2003 APG II system recognise the family and assign it to the order Caryophyllales in the clade core eudicots, although the 1998 APG system did not recognise such a family,

Flueggea tinctoria is a species of flowering shrub in the family Phyllanthaceae, endemic to the Iberian Peninsula.

Cissus verticillata, the princess vine or seasonvine, is an evergreen perennial vine in the grapevine family Vitaceae. It grows primarily in tropical regions near sea level, including many locations in the Caribbean region.

Marojejya darianii, the big-leaf palm or Ravimbe Palm, is a species of flowering palm tree in the Palm Family (Arecaceae or Palmae). It is found only in the rainforests of northeastern Madagascar and was completely unknown to the larger world until 1984 when it was discovered by Dr. Mardy Darian. It is critically endangered, and threatened with extinction due to habitat loss. It is important because it bears the largest simple leaves (undivided, unlobed) of any known tree; up to thirty feet (9.1 meters) long by up to four feet (1.2 meters) wide.

Banksia seminuda, commonly known as the river banksia, is a tree in the family Proteaceae. It is found in southwest Western Australia from Dwellingup (32°42′ S) to the Broke Inlet east of Denmark (34°57′ S). It is often mistaken for, and was originally considered a subspecies of, the Banksia littoralis (swamp banksia). Stephen Hopper described the subspecies remanens as a short-leaved shrubby form found in the coastal sands below granite outcrops in the Walpole-Nornalup National Park. However, George does not feel this form warrants taxonomic recognition as it lies within the normal

Rafflesia pricei is a parasitic flowering plant endemic to Borneo. It is named after amateur botanist William Price, who discovered the species on Mount Kinabalu in the 1960s. The Rafflesia Forest Reserve was established mainly to protect the species.

Rafflesia micropylora is a parasitic plant species of the genus Rafflesia. It is endemic to Sumatra in Indonesia. This species was named because of the small opening of its diaphragm or corona. The flowers are 30–60 cm diameter, with the diaphragm opening only 3–9 cm diameter, with an angular (rather than smoothly rounded) margin. Unlike the bold markings of species like R. arnoldi, R. micropylora is covered with a myriad of tiny markings. The very small aperture of the corona makes its identification easy.

Campomanesia phaea is a species of plant in the family Myrtaceae. The plant is endemic to the Atlantic Forest ecoregion in southeastern Brazil. It is found in the states of Paraná, Rio de Janeiro, São Paulo. In Brazil its fruit is called cambuci and the tree cambucizeiro. Not to be confused with cambucá.

Bognera is a monotypic genus of flowering plants in the family Araceae. The single species that makes up the genus is Bognera recondita. The word recondita means "hidden" referring to the fact that the plant is only found in remote areas of Amazonian Brazil near the Peruvian border. The species was discovered in the late 1970s and was originally placed in the genus Ulearum, as Ulearum reconditum Madison, Aroideana 3: 101 (1980). In 1984, a new genus was created in Taxon vol.33 on page 690, and Bognera was named after the German Aroid specialist Josef Bogner (b. 1939), who was a botanist,

Rafflesia gadutensis is a parasitic plant species of the genus Rafflesia. It is native to the Indonesian island of Sumatra. R. gadutensis was named after the place where it was first collected, Ulu Gadut, in West Sumatra.

Nepenthes eymae is a tropical pitcher plant endemic to Sulawesi in Indonesia, where it grows at elevations of 1,000–2,000 m (3,300–6,600 ft) above sea level. It is very closely related to N. maxima, from which it differs in its wine glass-shaped upper pitchers. The specific epithet eymae honours Pierre Joseph Eyma, a Dutch botanist who worked extensively in the Dutch East Indies and who originally discovered the species.

Neolamarckia is a genus with one or two species of trees native to the Old World tropics. It has often been confused with other genera, particularly Nauclea and Neonauclea to such an extent that descriptions of Neolamarckia may state incorrectly that its fruit is a capsule.

It produces dainty, colourful pitchers reaching only a few centimetres in height. These traps are red speckled on a yellowish background, giving them a "hand painted" appearance.

Vexatorella is a genus containing four species of flowering plant, commonly known as vexators, in the family Proteaceae. The genus is endemic to the Cape Floristic Region of South Africa. The name means “little trouble-maker”, given with reference to the initial difficulties of placing V. latebrosa within the family. All species are shrubs which occur in dry fynbos habitats on the fringes of the Succulent Karoo ecoregion. The inflorescences are similar to those of the related leucospermums but also share features of the leucadendrons, with the floral bracts becoming woody and enlarged
