The Cucurbitales are an order of flowering plants, included in the rosid group of dicotyledons. This order mostly belongs to tropical areas, with limited presence in subtropical and temperate regions. The order includes shrubs and trees, together with many herbs and climbers. One major characteristic of the Cucurbitales is the presence of unisexual flowers, mostly pentacyclic, with thick pointed petals. The pollination is usually performed by insects, but wind pollination is also present.
The Cucurbitaceae, also called cucurbits or the gourd family, are a plant family consisting of about 965 species in 101 genera. Those most important to humans are the following:
Gourds include the fruits of some flowering plant species in the family Cucurbitaceae, particularly Cucurbita and Lagenaria. The term refers to a number of species and subspecies, many with hard shells, and some without. One of the earliest domesticated types of plants, subspecies of the bottle gourd, Lagenaria siceraria, have been discovered in archaeological sites dating from as early as 13,000 BCE. Gourds have had numerous uses throughout history, including as tools, musical instruments, objects of art, film, and food.
Cucurbita is a genus of herbaceous fruits in the gourd family, Cucurbitaceae, native to the Andes and Mesoamerica. Five edible species are grown and consumed for their flesh and seeds. They are variously known as squash, pumpkin, or gourd, depending on species, variety, and local parlance. Other kinds of gourd, also called bottle-gourds, are native to Africa and belong to the genus Lagenaria, which is in the same family and subfamily as Cucurbita, but in a different tribe. These other gourds are used as utensils or vessels, and their young fruits are eaten much like those of the Cucurbita species.
Cucurbita pepo is a cultivated plant of the genus Cucurbita. It yields varieties of winter squash and pumpkin, but the most widespread varieties belong to the subspecies Cucurbita pepo subsp. pepo, called summer squash.
The scarlet gourds are a genus with 25 species. It is distributed in sub-Saharan Africa and with one species, C. grandis also in South Asia and Southeast Asia, and it is also introduced into the New World. Incidentally, C. grandis is also a cultivated crop and it is used for culinary and medical purposes.
Cucurbita ficifolia is a species of squash, grown for its edible seeds, fruit, and greens. It has common names including Asian pumpkin, black seed squash, chilacayote, cidra, fig-leaf gourd, and Malabar gourd. Compared to other domesticated species in its genus, investigators have noted that samples of C. ficifolia from throughout its range are relatively similar to one other in morphology and genetic composition. Variations do occur in fruit and seed color, some isozymes, and photoperiod sensitivity.
Sicana is a small genus of flowering plants in the family Cucurbitaceae. There are three or four species, found in rainforest and secondary scrub in the Caribbean and Central America.
Tetrameles is a genus of flowering plants in the family Tetramelaceae with one species, Tetrameles nudiflora. It grows as a large deciduous tree and is found across southern Asia from India through southeast Asia, Malesia, and into northern Australia.
Dendrosicyos is a monotypic genus in the plant family Cucurbitaceae. The only species is Dendrosicyos socotranus, the cucumber tree. The species is endemic to the island of Socotra in Yemen, and is the only species in the Cucurbitaceae to grow in a tree form. The species name was originally spelled D. socotrana, but this is corrected to masculine grammatical gender according to the International Code of Nomenclature for algae, fungi, and plants.
Cucurbita argyrosperma, also called the cushaw squash and silver-seed gourd, is a species of winter squash originally from the south of Mexico. This annual herbaceous plant is cultivated in the Americas for its nutritional value: its flowers, shoots, and fruits are all harvested, but it is cultivated most of all for its seeds, which are used for sauces. It was formerly known as Cucurbita mixta.
Zanonia is a monotypic genus in the flowering plant family Cucurbitaceae.
Ibervillea macdougalii is a species of flowering plant of the Cucurbitaceae or gourd family. Also called the Tumamoc globeberry, it is native to the Sonoran Desert, and is found in Arizona, Baja California Norte, Sonora, and Zacatecas.
The Cucurbiteae are a tribe of the subfamily Cucurbitoideae, which is part of the flowering plant family Cucurbitaceae (gourds). Species are usually monoecious herbaceous annuals or woody lianas.
Cayaponia is among the largest genera in the gourd family, Cucurbitaceae, with 74 species. The plants are referred to as melonleaf. They are common from the southern United States to South America. Some species are also found in western Africa, Madagascar, and Fernando de Noronha, which is about 354 km (220 mi) off the coast of Brazil.
Selysia bidentata is a species of the genus Selysia native to Panama. It is highly similar to S. smithii. It has ovate seeds and there are 6–9 of them in each fruit. The fruits turn from green to red at maturity. The leaves have three lobes. Selysia bidentata can be distinguished from the 3 other species of Selysia by its bidentate seeds. Seeds of the other three species are shaped like arrowheads.
Actinostemma is a genus of flowering plant in the gourd family Cucurbitaceae. It is native to east Asia. They are slender, weakly twining/climbing annual herbs.
Echinopepon is a genus of flowering plants in the family Cucurbitaceae, native to the southwestern United States, Mexico, Central America, and South America. Tendrillate vines, their prickly fruits are operculate, with the prickles themselves being stipitate glandular.
Hemsleya is a genus of flowering plants belonging to the family Cucurbitaceae.
