Description:Species Description - Quite different in aspect from its relative Quamoclit Quamoclit, but with similar flowers and fruits, this broad-leaved, annual vine also has wide distribution nearly throughout tropical America, and ranges north to Pennsylvania, Missouri, and Arizona; in Porto Rico growing in thickets and woodlands, on banks and along streams, mostly at lower elevations. We regard the species as indigenous; it is the type of the genus. The vine is occasionally planted for ornament, as also a hybrid with the Cypress-vine. Coral is another Spanish name. An account of the genus may be found with our description of Quamoclit Quamoclit. Quamoclit coccinea (scarlet flowers), is a smooth, or finely hairy vine, about 2 meters long, or shorter. The deeply heart-shaped, ovate, or nearly orbicular, long-pointed leaves are from 5 to 15 centimeters long, with continuous margins, or angulate-lobed, and usually a heart-shaped base, and slender stalks. The flowers are borne few, or several together on a slender stalk usually not longer than the leaves; the oblong, or ovate, long-tipped sepals are about 4 millimeters long in flower, enlarging in fruit; the corolla varies from 2 to 4 centimeters in length, its spreading limb obscurely 5-lobed. The nearly globular, 4-valved capsule is from 6 to 8 millimeters in diameter. A race with orange flowers was detected by Mrs. Britton at Rio Jueyes, in 1931.
