Both Cucurbita and Annona are considered what?
Cucurbita Cucurbita (Latin for gourd) is a genus of herbaceous vines in the gourd family, Cucurbitaceae, also known as cucurbits, native to the Andes and Mesoamerica. Five species are grown worldwide for their edible fruit, variously known as squash, pumpkin, or gourd depending on species, variety, and local parlance, and for their seeds. First cultivated in the Americas before being brought to Europe by returning explorers after their discovery of the New World, plants in the genus "Cucurbita" are important sources of human food and oil. 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 Cucurbita species.
Cucurbita argyrosperma Cucurbita argyrosperma, also the Japanese pie pumpkin or cushaw pumpkin, 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".
