Texas Flowers in Natural Colors

by Eula Whitehouse

GOURD FAMILY (Cucurbitaceae)

WILD BALSAM GOURD

Tendrils mostly present, stems often prostrate; flowers usually unisexual; calyx tubular, 5-lobed; petals united or separate; stamens usually 3, one anther always 1-celled, the other two 2-celled; ovary inferior.

Wild Balsam Gourd (Ibervillea lindheimeri) has bright scarlet balls about an inch in diameter and makes conspicuous spots of color on fences in the fall. The vine is slender, bearing small yellow flowers in the spring. The fruits are green at first, turning orange and then a scarlet red. Sometimes they are a little longer than broad and pointed at the end. The few leaves are thick and deeply 3-5-lobed. It ranges from Texas to California.

The garden balsam (Impatiens balsamina) bears no relation to this plant. The vines in cultivation known as balsam apple and balsam pear are, however, members of the gourd family and were introduced from the Old World tropics. Watermelons, cantaloupes, cucumbers, squashes, pumpkins, and gourds are well-known members of the gourd family.

WILD GOURD

Wild Gourd. Mock Orange (Cucurbita foetidissima) has long trailing stems which are often 15 feet long and may be 25 feet long. It is readily distinguished by its large gray-green triangular leaves which are somewhat 3-5-lobed. The leaf-blades are 4-12 inches long, and the leaf-stalk is about half the length of the blade. The star-shaped yellow flowers, about three inches broad, are almost hidden by the leaves, the staminate and pistillate flowers being borne on different plants.

The ovoid gourds, which at first are green variegated with a lighter green, turn quite yellow at maturity. The resemblance of the yellow fruit to oranges has given rise to the common name, mock orange. The gourds are about three inches long. They are not edible, as the pulp is fibrous and bitter. Mexicans use the plant as a soap substitute by mashing the gourds or the roots in water. They call it “chilicoyote” or “calabacilla.” The pumpkins and squashes, whose origin is somewhat obscure, are close relatives of the gourd.
