A cactus is a member of the plant family Cactaceae, a family comprising about 127 genera with some 1750 known species of the order Caryophyllales. The word "cactus" derives, through Latin, from the Ancient Greek κάκτος, kaktos, a name originally used by Theophrastus for a spiny plant whose identity is now not certain. Cacti occur in a wide range of shapes and sizes. Most cacti live in habitats subject to at least some drought. Many live in extremely dry environments, even being found in the Atacama Desert, one of the driest places on earth. Cacti show many adaptations to conserve water. Almost all cacti are succulents, meaning they have thickened, fleshy parts adapted to store water. Unlike many other succulents, the stem is the only part of most cacti where this vital process takes place. Most species of cacti have lost true leaves, retaining only spines, which are highly modified leaves. As well as defending against herbivores, spines help prevent water loss by reducing air flow close to the cactus and providing some shade. In the absence of leaves, enlarged stems carry out photosynthesis. Cacti are native to the Americas, ranging from Patagonia in the south to parts of western Canada in the north—except for Rhipsalis baccifera, which also grows in Africa and Sri Lanka.
Kumquats are a group of small fruit-bearing trees in the flowering plant family Rutaceae. They were previously classified as forming the now-historical genus Fortunella, or placed within Citrus, sensu lato.
The flowering plants, also known as Angiospermae, or Magnoliophyta, are the most diverse group of land plants, with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. Etymologically, angiosperm means a plant that produces seeds within an enclosure; in other words, a fruiting plant. The term comes from the Greek words angeion and sperma (seed)
Pistacia is a genus of flowering plants in the cashew family, Anacardiaceae. It contains 10 to 20 species that are native to Africa and Eurasia from the Canary Islands, all of Africa, and southern Europe, warm and semidesert areas across Asia, and North America from Mexico to warm and semidesert United States, such as Texas or California.
Lodoicea, commonly known as the sea coconut, coco de mer, or double coconut, is a monotypic genus in the palm family. The sole species, Lodoicea maldivica, is endemic to the islands of Praslin and Curieuse in the Seychelles. It formerly also was found on the small islets of St Pierre, Chauve-Souris and Ile Ronde, all located near Praslin, but had become extinct there for a time until recently reintroduced. The name of the genus, Lodoicea, may be derived from Lodoicus, one Latinised form of Louis, in honour of King Louis XV of France. Other sources say that Lodoicea is from Laodice, the daughter of Priam and Hecuba.
Conium is one of more than 400 genera of flowering plants in the carrot family Apiaceae. As of December 2020, Plants of the World Online accepts six species.
A frugivore is an animal that thrives mostly on raw fruits, succulent fruit-like vegetables, roots, shoots, nuts and seeds. Approximately 20% of mammalian herbivores eat fruit. Frugivores are highly dependent on the abundance and nutritional composition of fruits. Frugivores can benefit or hinder fruit-producing plants by either dispersing or destroying their seeds through digestion. When both the fruit-producing plant and the frugivore benefit by fruit-eating behavior the interaction is called mutualism.
Pandanus tectorius is a species of Pandanus (screwpine) that is native to Malesia, eastern Australia, and the Pacific Islands. It grows in the coastal lowlands typically near the edge of the ocean. Common names in English include thatch screwpine, Tahitian screwpine, hala tree, pandanus, and pu hala in Hawaiian. The fruit is sometimes known as hala fruit.
Eremophila is a genus of more than 260 species of plants in the figwort family, Scrophulariaceae all of which are endemic to mainland Australia.. Eremophilas are widespread in the arid areas of Australia, especially Western Australia and range in size from low-growing shrubs to small trees. The petals are joined, at least at their bases, into a tube with the upper petals different in size and shape from the lower ones. Some species have common names including emu bush, poverty bush or fuchsia bush, reflecting the belief that emus eat the fruit, their arid environment or a superficial resemblance to the flowers of plants in the genus Fuchsia.
Ricinodendron is a plant genus in the family Euphorbiaceae first described as a genus in 1864. It includes only one known species, Ricinodendron heudelotii, native to tropical Africa from Senegal + Liberia east to Sudan and Tanzania and south to Mozambique and Angola. It produces an economically important oilseed. The tree is known as munguella (Angola), njangsa (Cameroon), bofeko (Zaire), wama (Ghana), okhuen (Nigeria), kishongo (Uganda), akpi, djansang, essang, ezezang and njasang. Two varieties of the tree species are recognized R. heudelotii var. heudelotii in Ghana and R. heudelotii var. africanum in Nigeria and westwards.

A pitaya or pitahaya is the fruit of several different cactus species indigenous to the Americas. Pitaya usually refers to fruit of the genus Stenocereus, while pitahaya or dragon fruit refers to fruit of the genus Selenicereus, both in the family Cactaceae.
