Cucurbita moschata, which encompasses various cultivars of pumpkin and winter squash, is a plant species in the gourd family (Cucurbitaceae) cultivated in warm areas around the world as food and animal fodder. Popular cultivars include butternut, winter crookneck, and cushaw, and numerous types developed in Japan and China.
The names “winter squash” and “pumpkin” are also applied to the cultivars of C. maxima, C. mixta and C. pepo. Because the common names are used to refer to several different species, and those species may also have other common names, it can be difficult to ascertain which varieties are derived from which species. In the U.S., cultivars with round, orange fruits are generally referred to as pumpkins, while fruits with other shapes and colors are called winter squashes, regardless of the species.
C. moschata likely originated in Mexico and Central America, and was already widely cultivated in North and South America before the arrival of Europeans. Archaeologists have found evidence of C. moschata in Peruvian sites dated from 4,000–3,000 B.C., and in Mexican sites from 1440–400 B.C., suggesting a long history of domestication and cultivation.
C. moschata is better adapted to hot, humid climates than C. pepo and C. maxima, and is resistant to squash vine borers, Melittia cucurbitae, so these varieties are popular for cultivation in the southeastern U.S. A C. moschata variety, the Dickenson field pumpkin, is the dominant source of canned pumpkin (and, therefore, pumpkin pies) in the U.S. However, giant pumpkins, with fruits weighing over 45 kg (100 pounds) come from cultivars of C. maxima.
C. moschata plants are frost-intolerant monoecious annuals. Stems are hairless or soft hairy, trailing or climbing vines growing to 3 meters. Leaves are simple, alternate, and shallowly lobed, often with white spots along the veins. The peduncle (stem that holds the fruit) is five-angled and flares outward where attached to the fruit. Fruits (technically referred to as pepos) are relatively large, with shapes ranging from globose to oblong to flattened. Seeds are 16–20 mm long.
Winter squashes and pumpkins, which are low in calories and high in fiber and vitamin A, are usually eaten as a vegetable, in purees, soups, or pies. Seeds are high in protein, oil, and minerals, and are eaten raw, toasted, or pressed to make oil. Male flowers are coated with breading or batter and made into fritters. In South America, tips of young vines are boiled and eaten.
C. moschata has numerous traditional medicinal uses in South and Central America. Seeds are toasted and eaten to kill worms and other intestinal parasites and used as a diuretic; a preparation from the flowers has been used to treat measles and smallpox. Pumpkin seeds are sometimes used as a natural worming agent for sheep and goats by organic farmers, but their efficacy has not been clearly demonstrated.
World production of pumpkins, squashes, and gourds (across all species of Cucurbitaceae) was 22.1 million tons harvested from 1.7 million hectares in 2009, valued at $5.2 billion U.S. dollars. Leading producers were China, Russia, India, the U.S., and Egypt.

Comments: Similar to the uses of C. pepo. In Mexico, the seeds are given with castor oil as an anthelmintic. The seed oil is applied to persistent ulcers in Venezuela, and a decoction of the flowers has been used to treat measles and small pox. Colombians report that a root infusion is febrifugal and also is applied to syphilitic ulcers. The seeds are said to be excellent vermifuges and taenifuges and the fruits are diuretic.
Cucurbita moschata is a species originating in either Central America or northern South America. It includes cultivars of squash and 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. Evolutionarily speaking the genus is relatively recent in origin as no species within the genus is genetically isolated from all the other species. C. moschata acts as the genetic bridge within the genus and is closest to the genus' progenitor. Cultivars include:
'Butternut' type, also "Bell" type. Robinson and Decker-Walters (1997) p. 80: "Three horticultural groupings of C. moschata cultivars are recognized in the commercial trade of North America: (...) Bell. Fruit bell-shaped to almost cylindrical." "The bell squash 'Butternut' is an important winter squash with excellent quality. It was selected for better fruit shape from the heirloom cultivar 'Canada Crookneck' and introduced by the Breck Seed Company in 1936. The elongated neck of the buff-coloured 'Butternut' fruit is generally straight but occasionally curved. The neck is entirely usable because the small seed cavity is confined to the bulbous base of the fruit. 'Waltham Butternut' is similar, but produces a higher proportion of fruits with straight necks. It was obtained by crossing 'New Hampshire Butternut' with an African plant introduction to the USA, and has been a very popular cultivar ever since its commercial introduction in 1970".
Cucurbita moschata Crookneck type. Similar to 'Butternut' with an elongated neck that twistes during cultivation. Cultives belonging to this group: in USA 'Neck pumpkin' and 'Pennsilvannia Dutch Crookneck' (upper photograph), in Italy and France 'Tromba d' Albenga', 'Tromboncino' (bottom photograph). 'Neck pumpkin' most popular in the Mid-Atlantic states of the United States, particularly in areas with an Amish influence. Also within this group 'Canada Crookneck' from which 'Butternut' was originated.
37 lb 'Long of Naples' squash. Belonging to Crookneck group.
A 'Long Island Cheese' Pumpkin - exterior resembles a wheel of cheese in shape, color, and texture. Robinson and Decker-Walters (1997) p. 80: "Three horticultural groupings of Cucurbita moschata cultivars are recognized in the commercial trade of North America: (..) Cheese. Fruit variable, but usually oblate with a buff-coloured rind."

Butternut squash (Cucurbita moschata), also known in Australia and New Zealand as Butternut pumpkin, is a type of winter squash. It has a sweet, nutty taste similar to that of a pumpkin. It has yellow skin and orange fleshy pulp. When ripe, it turns increasingly deep orange, and becomes sweeter and richer. It grows on a vine. The most popular variety, the Waltham Butternut, originated in Stow, Massachusetts.
In Australia it is regarded as a pumpkin, and used interchangeably with other types of pumpkin.
It is also commonly used in South Africa. It is often used in soup or can be cooked on a grill. Grilled butternut is normally either seasoned with spices such as nutmeg and cinnamon or the de-seeded centre stuffed with other vegetables for example Spinach and Feta before wrapped in foil and then grilled. The grilled butternut is often served as a side dish to “braai's” (barbecues) and the soup as a starter dish.

Preparation, precautions, allergic reactions
The fruit is prepared by removing the skin, stalk and seeds, which are not usually eaten or cooked. However, the seeds are edible, either raw or roasted and the skin is also edible and softens when roasted. One of the most common ways to prepare butternut squash is roasting. To do this, the squash is cut in half lengthwise, lightly brushed with cooking oil, and placed cut side down on a baking sheet. It is then baked for 45 minutes or until it is softened. Once roasted, it can be eaten in a variety of ways as outlined above.
