Cucurbitaceae (from the genus Cucurbita, the classical name for the gourd). Gourd Family. Fig. 56. Herbs, rarely shrubs, climbing, usually with branched tendrils: leaves alternate, more or less rounded; veins palmate: flowers usually unisexual, perigynous, regular; stamens 5, rarely separate, usually connate in 2 pairs and 1 free stamen (thus apparently, stamens 3), or monadelphous, inserted at the summit of the ovary; anthers 2-celled, the cells often queerly curved and contorted; carpels usually 3, rarely more or fewer; ovary inferior, mostly 3-celled, many-ovuled: fruit a dry berry with thick rind and spongy center (Pepo), or juicy with hard rind, very exceptionally dehiscent.

There are 87 genera and about 650 species, widely distributed over the earth but most abundant in the tropics; they are wanting in the cold regions. Several are wild in the eastern United States.

The gourds are cultivated as curiosities and for the fruit to be used as household utensils, e. g., bottle-gourds and calabash (Lagenaria). The leaves, stems, or roots of very many species contain bitter, subresinous substances which render them drastic purgatives. The roots of Bryonia alba (bryony) of Europe are highly purgative.

Cucurbitaceae (from the genus Cucurbita, the classical name for the gourd). Gourd Family. Fig. 56. Herbs, rarely shrubs, climbing, usually with branched tendrils: leaves alternate, more or less rounded; veins palmate: flowers usually unisexual, perigynous, regular; stamens 5, rarely separate, usually connate in 2 pairs and 1 free stamen (thus apparently, stamens 3), or monadelphous, inserted at the summit of the ovary; anthers 2-celled, the cells often queerly curved and contorted; carpels usually 3, rarely more or fewer; ovary inferior, mostly 3-celled, many-ovuled: fruit a dry berry with thick rind and spongy center (Pepo), or juicy with hard rind, very exceptionally dehiscent.

There are 87 genera and about 650 species, widely distributed over the earth but most abundant in the tropics; they are wanting in the cold regions. Several are wild in the eastern United States. The family is related to the Campanulaceae, possibly also to the Passifloraceae. The tendrils are usually borne singly at the nodes and are thought to be modified axillary branches. The fruits are exceedingly diverse and odd. Some are the largest fruits of the vegetable kingdom, others are very tiny. The gourds are very diverse in shape and color,—club-shaped, globular, or flattened from above, or curiously curved.

The family is of considerable economic importance. The fruits of many are edible; e. g., Cucurbita Pepo (pumpkin, summer crookneck squash), C. maxima (squash), C. moschala (winter crookneck squash), Cucumis Melo (muskmelon and other melons), C. sativa (cucumber), Citrullus vulgaris (watermelon).

Cucurbitaceae is a plant family commonly known as gourds or cucurbits and includes crops like cucumbers, squashes (including pumpkins), luffas, melons and watermelons. The family is predominately distributed around the tropics, where those with edible fruits were amongst the earliest cultivated plants in both the Old and New Worlds.

Most of the plants in this family are annual vines with large showy-blossoms, usually white or various shades of bright yellow to orange-yellow. The plants produce male and female flowers separately on the same plant, and the female flowers have inferior ovaries. The fruit is a kind of berry called a pepo.

Most of the plants in this family are readily susceptible to the larva of a particular moth, the Squash Borer.

Classification

There are about 118 extant genera in Cucurbitaceae, including 825 species. The following is the classification as given by Charles Jeffrey as of 1990.

Subfamily Zanonioideae (small striate pollen grains)

Subfamily Cucurbitoideae (styles united into a single column)
