Winter squash

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.

[2] Four species in the genus Cucurbita yield cultivars that are grown as winter squashes: C. argyrosperma, C. maxima, C. moschata, and C. pepo.

In New Zealand and Australian English, the term pumpkin generally refers to the broader category called winter squash elsewhere.

Winter squash seeds germinate best when the soil temperature is 21 to 35 °C (70 to 95 °F), with the warmer end of the range being optimal.

[1] The calabazas of the West Indies and the forms grown by the people of Mexico and Central America are not uniform, pure varieties but extremely variable in size, shape, and color.
