The Cucurbitaceae, also called cucurbits or the gourd family, are a plant family consisting of about 965 species in around 95 genera, of which the most important to humans are:
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.
Cucurbita ficifolia is a species of squash, grown for its edible seeds, fruit, and greens. It has many common names in English such as the fig-leaf gourd, Malabar gourd, black seed squash and cidra. Although it is closely related to other squashes in its genus, such as the pumpkin, it shows considerable biochemical difference from them and does not hybridize readily with them.
The Eastern Agricultural Complex in the woodlands of eastern North America was one of about 10 independent centers of plant domestication in the pre-historic world. Incipient agriculture dates back to about 5300 BCE. By about 1800 BCE the Native Americans of the woodlands were cultivating several species of food plants, thus beginning a transition from a hunter-gatherer economy to agriculture. After 200 BCE when maize from Mexico was introduced to the Eastern Woodlands, the Native Americans of the eastern United States and adjacent Canada slowly changed from growing local indigenous plants to a maize-based agricultural economy. The cultivation of local indigenous plants other than squash and sunflower declined and was eventually abandoned. The formerly domesticated plants returned to their wild forms.
Cucurbita palmata is a species of flowering plant in the squash family known by the common names coyote melon and coyote gourd. It is similar to Cucurbita californica, Cucurbita cordata, Cucurbita cylindrata, and Cucurbita digitata and all these species hybridize readily. It was first identified by Sereno Watson in 1876. These species form the only restricted xerophyte species group in the genus Cucurbita. Each member of this species group is native to the Southwestern United States and Northwestern Mexico where they are relatively uncommon. Each group member is found in hot, arid regions with low rainfall. They prefer soil that is loose, gravelly, and well-drained. C. palmata is native to northeastern Baja California, southeastern California, and southwestern Arizona to a point near the Colorado River. The juvenile leaves of C. cylindrata, C. cordata, C. digitata, and C. palmata show a high degree of similarity, but their mature leaves are visibly different, as are their root structures. C. palmata and C. digitata are sympatric, with C. palmata separating the ranges of C. digitata at the juncture of Baja California, California, and Arizona. C. palmata fruits are diffuse green mottle that turns yellow at maturity, striped, and round.
Cucurbita digitata is a species of flowering plant in the squash family known by the common names fingerleaf gourd and bitter squash. It is similar to Cucurbita californica, Cucurbita cordata, Cucurbita cylindrata, and Cucurbita palmata and all these species hybridize readily. These species form the only restricted xerophyte species group in the genus Cucurbita. Each member of this species group is native to the Southwestern United States and Northwestern Mexico where they are relatively uncommon. Each group member is found in hot, arid regions with low rainfall. They prefer soil that is loose, gravelly, and well-drained. C. digitata is native to northern Baja California at higher elevations, northern Sonora, Mexico, southern Arizona, and southwestern New Mexico. The juvenile leaves of C. cylindrata, C. cordata, C. digitata, and C. palmata show a high degree of similarity, but their mature leaves are visibly different, as are their root structures. C. palmata and C. digitata are sympatric, with C. palmata separating the ranges of C. digitata at the juncture of Baja California, California, and Arizona. C. digitata fruits are clear green mottle that turns yellow at maturity, striped, and round.
A pumpkin is a cultivar of winter squash that is round with smooth, slightly ribbed skin, and is most often deep yellow to orange in coloration. The thick shell contains the seeds and pulp. The name is most commonly used for cultivars of Cucurbita pepo, but some cultivars of Cucurbita maxima, C. argyrosperma, and C. moschata with similar appearance are also sometimes called "pumpkins".
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.
Cucurbita galeottii is a plant species of the genus Cucurbita. It is native to Oaxaca, Mexico. It has not been domesticated. There is very little known about this species. Nee reports that the species is a xerophyte and that Bailey only saw the species in photographs. It is only known from specimens that "lack roots, female flowers, fruits and seeds".
Cucurbita lundelliana is a mesophyte plant species of the genus Cucurbita. It is native to Mexico, Guatemala, and Belize. It has not been domesticated. It is found in the Yucatán region near sea level among limestone cliffs. In Guatemala it is found in Parque Nacional Yaxha Nakum Naranjo along Rio Ixtinto and near Laguna Julequito.
Cucurbita pedatifolia is a xerophyte plant species of the genus Cucurbita. It is native to Querétaro, Mexico. It has not been domesticated. While C. pedatifolia has been cross bred, results have met with limited success. It does not cross well with other species of Cucurbita. It is a close relative of Cucurbita radicans. Geographic location and genetics make it highly likely that Cucurbita scabridifolia is a naturally occurring hybrid of Cucurbita foetidissima and C. pedatifolia. It also has some mesophyte traits may represent a transitional state between the mesophytic Cucurbita and the xerophytic Cucurbita.
Cucurbita fraterna, also known as Cucurbita pepo subsp. fraterna, is a mesophyte plant species of the genus Cucurbita. It is native to Tamaulipas and Nuevo León, Mexico. It has not been domesticated. It is the progenitor and nearest relative of the domesticated species Cucurbita pepo and wild C. pepo is still found in the same areas as C. fraterna. It was formally described by Liberty Hyde Bailey in 1943, in Gentes Herbarum.
Cucurbita texana, also known as Cucurbita pepo subsp. texana and Texas gourd, is a mesophytic plant species of the genus Cucurbita. It is native to Texas, primarily the southeastern region. It is found only in the wild. It is possibly a progenitor and close relative of the domesticated species Cucurbita pepo, though it and wild C. pepo are native to different areas. Cucurbita fraterna is also closely related. It was first collected 1835 by J. L. Berlandier in southern Texas. It was formally described as Tristemon texanus by George Heinrich Adolf Scheele in 1848 and transferred to the genus Cucurbita by Asa Gray in 1850.
Cucurbita martinezii is a plant species of the genus Cucurbita native to Veracruz, Mexico. Locals use halved fruit shells as shot glasses for alcoholic drinks. It has not been domesticated. It is generally found in areas with rivers and forests.
Cucurbita andreana is a plant species of the genus Cucurbita, since 1982 in the rank of a C. maxima subspecies, C. maxima subsp. andreana, the wild relative of C. maxima subsp. maxima cultivated subspecies. It is native to Argentina and Uruguay. C. andreana fruits are smaller and not palatable, those of C. maxima are bigger and palatable.
Cucurbita sororia is a plant species of the genus Cucurbita, sometimes considered to be a subspecies of Cucurbita argyrosperma, C. a. subsp. sororia. It ranges from northern Mexico to Nicaragua, mostly along the Pacific coast. This species was originally considered closely related to Cucurbita texana but C. sororia was later shown to be an ancestor of Cucurbita argyrosperma, with which it hybridizes well.
Guilá Naquitz Cave in Oaxaca, Mexico is the site of early domestication of several food crops, including teosinte, squash from the genus Cucurbita, bottle gourds, and beans. This site is the location of the earliest known evidence for domestication of any crop on the continent, Cucurbita pepo, as well as the earliest known domestication of maize.
Cucurbita californica is a species of flowering plant in the squash family.
