There is no single gourd species
Whether a squash is called a gourd depends on how broadly the word is being used. Gourd commonly describes several groups in the cucurbit family. Illinois Extension discusses ornamental Cucurbita gourds, hard-shelled Lagenaria gourds and sponge gourds in Luffa. Treating gourd as one exact species would hide these differences. [1]
Some ornamental gourds share a species with squash
The overlap is more than resemblance. Iowa State lists ornamental gourds alongside zucchini and several pumpkins within Cucurbita pepo. Bottle gourd, however, is Lagenaria siceraria. A display label saying gourd does not tell you which of those plants produced the fruit. For identification, the botanical name is more precise than the decorative or culinary category. [2]
Interpreting a hypothetical autumn display
Imagine a basket marked “squash and gourds.” That heading is useful for a seasonal display, but it does not establish that every item is an edible squash. Keep produce sold for eating separate from unidentified decorative fruit, and use the named crop rather than appearance when selecting a recipe ingredient. Shared family membership alone is not an edibility test. [1][2]
