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. Many gourds have large, bulbous bodies and long necks, such as Dipper Gourds, many variations of Bottle Gourd and caveman club gourds. 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 BC. 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.
Straightneck squash is a cultivated variety of Cucurbita pepo grown as a type of summer squash that is usually yellow-colored. It is also known as yellow squash, though other squashes, such as crookneck squash, may also be known by that name. It has mildly sweet and watery flesh, and thin tender skins that can be left on the fruit for many types of recipes. It was almost certainly domesticated in the eastern United States, although other variants of the same species were domesticated in Mesoamerica. This squash grows on vined plants reaching 60–90 cm (2.0–3.0 ft) in height that thrive in mild weather. It is well known as an item in American cooking where it is fried, microwaved, steamed, boiled, or baked. It is often used in recipes interchangeably with zucchini. A good yellow summer squash will be small and firm with tender skin free of blemishes and bruising. It is available all year long in some regions, but is at its peak from early through late summer. One similar inedible C. pepo variety is C. pepo var. ovifera.
A pumpkin seed, also known as a pepita, is the edible seed of a pumpkin or certain other cultivars of squash. The seeds are typically flat and oval with one axis of symmetry, have a white outer husk, and are light green after the husk is removed. Some pumpkin cultivars are huskless and are grown only for their edible seed. The seeds are nutrient- and calorie-rich, with an especially high content of fat, protein, dietary fiber, and numerous micronutrients. Pumpkin seed can refer either to the hulled kernel or unhulled whole seed and most commonly refers to the roasted end product used as a snack.
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, Malabar gourd and Kahurura in Gikuyu. 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.
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 moschata is a species originating in either Central America or northern South America. It includes cultivars known as squash or pumpkin. C. moschata cultivars are generally more tolerant of hot, humid weather than cultivars of C. maxima or C. pepo. They also generally display a greater resistance to disease and insects, especially to the squash vine borer. Commercially made pumpkin pie mix is most often made from varieties of C. moschata. The ancestral species of the genus Cucurbita were present in the Americas before the arrival of humans. No species within the genus is fully genetically isolated from all the other species. C. moschata can be hybridized with all other species. It has been suggested that this shows that the species of Cucurbita have diversified more recently than those of related genera such as Cucumis and Citrullus.
The name squash bee, also squash and gourd bee, is applied to two related genera of bees in the tribe Eucerini; Peponapis and Xenoglossa. Both genera are oligoleges on the plant genus Cucurbita and closely related plants, although they usually do not visit watermelon, cucumber, and melon plants. They are small genera, containing only 13 and 7 described species, respectively, and their combined range is nearly identical to the range of Cucurbita in the New World, from South America to North America. Their range has become somewhat expanded along with the movement of cucurbits into other areas.
Crookneck squash, also known as yellow squash, is a cultivar of Cucurbita pepo, the species that also includes some pumpkins and most other summer squashes. The plants are bushy and do not spread like the plants of winter squash and pumpkin. Most often used as a summer squash, it is characterized by its yellow skin and sweet yellow flesh, as well as its distinctive curved stem-end or "crooked neck". It should not be confused with crookneck cultivars of Cucurbita moschata, such as the winter squash 'Golden Cushaw', or the vining summer squash 'Tromboncino'. Its name distinguishes it from another similar-looking variety of C. pepo, the straightneck squash, which is also usually yellow. There is one similar non-edible C. pepo variety: C. pepo var. ovifera.
Delicata squash is a variety of winter squash with cylindrical fruits that are cream-coloured and striped in green or orange. As its name suggests, it has characteristically a delicate rind. It is also known as peanut squash, Bohemian squash, or sweet potato squash. It is a very sweet variety with a thin, edible skin and is typically cut into half rounds and roasted. It is a cultivar of the species Cucurbita pepo, which also includes the summer squash varieties pattypan squash, zucchini, and yellow crookneck squash, as well as winter squash varieties including acorn squash, spaghetti squash, and most pumpkins used as Jack-o-lanterns.
Winter squash is an annual fruit representing several squash species within the genus Cucurbita. Late-growing, less symmetrical, odd-shaped, rough or warty varieties, small to medium in size, but with long-keeping qualities and hard rinds, are usually called winter squash. They differ from summer squash in that they are harvested and eaten in the mature stage when their seeds within have matured fully and their skin has hardened into a tough rind. At this stage, most varieties of this vegetable can be stored for use during the winter. Winter squash is generally cooked before being eaten, and the skin or rind is not usually eaten as it is with summer squash.
Gem squash is a variety of summer squash that may have been domesticated from two wild varieties; Cucurbita texana found in the southern and central United States and Cucurbita fraterna found in Mexico. It bears notable similarities to Tatume squash or Calabacita, a Cucurbita pepo variety widely grown in Mexico and parts of Texas with a similar vining or climbing and fruiting habit The dark green spherical fruit, when fully ripe, is about the size of a tennis ball. The young fruit is often harvested before it is fully ripe when it has a more delicate texture flavor.
Cucurbita maxima, one of at least five species of cultivated squash, is one of the most diverse domesticated species. This species originated in South America from the wild subspecies Cucurbita maxima subsp. andreana over 4,000 years ago. Cucurbita maxima, known for modern varieties as Hubbard, Delicious, Marblehead, Boston Marrow, and Turks Turban, originated in northern Argentina near the Andes or in certain Andean valleys. Secondary centers of diversity include India, Bangladesh, Myanmar, and the southern Appalachians.
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 cultivated winter squash in the genus Cucurbita. The term is most commonly applied to round, orange-colored squash varieties, though it does not possess a scientific definition and may be used in reference to many different squashes of varied appearance.
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.
Peponapis pruinosa is a species of solitary bee in the tribe Eucerini, the long-horned bees. Its common name is the eastern cucurbit bee. It may be called the squash bee, but this name can also apply to other species in its genus, as well as the other squash bee genus, Xenoglossa. This bee occurs in North America from the East Coast of the United States to the West Coast and into Mexico. It is an oligolege, specializing on a few host plants, the squashes and gourds of genus Cucurbita. Its range expanded as human agriculture spread throughout North America and squash plants became more abundant and widespread. It may also have spread naturally as the range of its favored wild host plant Cucurbita foetidissima expanded.
Cucurbita ecuadorensis is a species of squash, described in 1965 as growing wild in Ecuador. Like most wild gourds and squashes, it is a creeping vine and is often found climbing over other vegetation. It has been found only in the western provinces of Guayas and Manabí. There is evidence that it was domesticated in Ecuador around 10,000 years ago, likely for its seeds, but no direct records exist and it is no longer cultivated. It is resistant to many diseases of cultivated Cucurbita species, and has been used to breed resistance to several diseases into common squashes. For example, researchers at Cornell University used Cucurbita ecuadorensis to breed resistance to papaya ringspot virus, watermelon mosaic virus, and powdery mildew, into common Cucurbita maxima cultivars. Cucurbita ecuadorensis is listed on the IUCN Red List as vulnerable and is found protected in the Machalilla National Park.
Thomas Wallace Whitaker was an American botanist and horticulturist who spent most of his career working as a geneticist for the United States Department of Agriculture (USDA). He specialized in the study of economically important plants such as squashes, investigating their systematics and resistance to disease.
