Pumpkin

Pumpkin refers to certain cultivars of squash, most commonly those of Cucurbita pepo, that are round, with smooth, slightly ribbed skin and deep yellow to orange coloration. The thick shell contains the seeds and pulp. Some exceptionally large cultivars of squash with similar appearance have also been derived from Cucurbita maxima. Specific cultivars of winter squash derived from other species, including C. argyrosperma, and C. moschata, are also sometimes called “pumpkin”. In New Zealand and Australian English, the term “pumpkin” generally refers to the broader category called winter squash elsewhere.
