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 foetidissima is a tuberous xerophytic plant found in the central and southwestern United States and northern Mexico. It has numerous common names, but is most commonly called the buffalo gourd in English. The type specimen was collected from Mexico by Alexander von Humboldt and Aimé Bonpland sometime before 1817. In Latin, foetidissima means most unpleasant smell.
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 okeechobeensis, the Okeechobee gourd, is a species of gourd in the family Cucurbitaceae, native to Mexico and the United States. There are two subspecies; one is endemic to Florida, primarily in the region around Lake Okeechobee, the other to the State of Veracruz in eastern Mexico. Once abundant, it has state and federal listing as an endangered species. One of its peculiarities is the yellow corolla not so common in other Cucurbita species.
Cucurbita radicans, commonly known in Mexico as calabacilla or calabaza de coyote , is a species of gourd found growing wild, but also cultivated, in southern Mexico. The type specimen was collected growing in rocks below a mountain near Guadalupe in the vicinity of Mexico City ; other specimens were also ubiquitous in the area; in corn fields and gardens, either being cultivated, or as invaders. It is a close relative of Cucurbita pedatifolia.
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 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 cordata is a species of flowering plant in the squash family. It is similar to Cucurbita californica, Cucurbita cylindrata, Cucurbita digitata, 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. cordata is found only in the vicinity of Bahía de los Ángeles, Baja California. Botanists Bemis and Whitaker suggest that C. cordata and C. cylindrata may be a case of sympatric speciation. 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. cordata fruits are gray green, striped, and round.
Cucurbita cylindrata is a species of flowering plant in the squash family. It is similar to Cucurbita californica, Cucurbita cordata, Cucurbita digitata, 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. cylindrata is found only in the middle portion of Baja California, mostly in Baja California Sur. Botanists Bemis and Whitaker suggest that C. cordata and C. cylindrata may be a case of sympatric speciation. 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. cylindrata fruits are dark green, striped, and round.
Rubus aptatus, the drybank dewberry, is a rare North American species of flowering plant in the rose family. It is found in scattered locations in the northeastern United States.
