Squash - el zapallo
From Peace Corps Wiki
Zapallo in Spanish indicates any squash. The most common kinds are zucchini and auyama, which is a trype of winter squash.
Tips: Many people get frustrated that their vines are flowering, but not producing squash. This is usually because the vines start by flowering male blossoms, then start flowering male and female. You can tell which flowers are female because they have a small lump under the flower that will become the squash.
