The squashes belong to at least three species. The 

 summer squashes (of the crookneck and scallop type) are

 species. The large field squashes of the Hubbard and 

 turban types are Cucurbita maxima. The winter squashes 

 are mostly of the species C. moschata, although forms of 

 C. maxima are good keepers. The summer squashes are 

 probably native to America. These do not intercross 

 with the winter squashes. Large squashes of any of the 

 three species are usually called pumpkins. Squashes of 

 some kind are grown in several parts of the tropics, and 

 when acclimated often give better results than the first 

 sowing of seed grown in a colder climate.

 melons and cucumbers, or any other combination of these 

 vegetables, are planted together, they will produce hybrids,
