Juss.[1]

The Cucurbitaceae are a plant family, sometimes called the gourd family, consisting of over a hundred genera, the most important of which are:

The plants in this family are grown around the tropics and in temperate areas, where those with edible fruits were among the earliest cultivated plants both in the Old and New World. The Cucurbitaceae family ranks among the highest of plant families for number and percentage of species used as human food.[2]

The Cucurbitaceae consist of approximately 125 genera and 960 species, mainly in regions tropical and subtropical. All species are sensitive to frost. Most of the plants in this family are annual vines but there are also woody lianas, thorny shrubs, and trees (Dendrosicyos). Many species have large, yellow or white flowers. The stems are hairy and pentangular. Tendrils are present at 90° to the leaf petioles at nodes. Leaves are exstipulate alternate simple palmately lobed or palmately compound. The flowers are unisexual, with male and female flowers on different plants (dioecious) or on the same plant (monoecious). The female flowers have inferior ovaries. The fruit is often a kind of modified berry called a pepo.

Classification[edit]

The about 125 existent genera in Cucurbitaceae include 960 species. The following is the classification as given by Charles Jeffrey as of 1990. However, a 2011 based on genetics does not support this taxonomy with 2 subfamilies and 8 tribes , but rather 15 tribes, 5 of them new, consisting of 95 genera, not 121.[3]
