J. H. Trumbull, in a letter quoted in Bull. Torrey Bot. Club, Vol. 6:69-70; 1876, states, "I could never discover where the doubt came in, as to the American origin of several well-known varieties of these gourds, or Millions as some call them, or Pompions as I may call them. In England, the name 'squash' was understood to be of American origin. Robert Boyle mentions his experiment with the seed of 'squash' which is an Indian kind of pompion that grows apace." "Beverley (History of Virginia, 124) describes the Macocks as 'a sort of Melopepones, or lesser sort of Pompion or Cashaw’ squash, or Squouter-squash, which is their name among the northern (i.e. New England) Indians." According to Alphonse de Candolle in "Origin of Cultivated Plants, 1892," the pumpkins cultivated by the Romans and in the middle-ages were Curcurbita maxima, and those of the natives of North America, seen by different travelers in the seventeenth century, were Cucurbita Pepo.
