About Jacquemontia tamnifolia (L.) Griseb.
Jacquemontia tamnifolia (L.) Griseb. has ovate to elliptic-ovate leaves that are 5 to 12 centimeters long, with acuminate tips and usually cordate bases, though the base may occasionally be rounded. Peduncles are equal to or longer than the leaf they subtend. The capitate inflorescence is roughly 2 to 3 centimeters in diameter, and is subtended by lanceolate to elliptic, leafy bracts. Its sepals are lanceolate to subulate and densely covered with tawny-colored (fulvous) hairs. The corolla is blue, funnelform, and 1 to 2 centimeters in diameter. The stigma has two ovoid or oblong lobes; the styles are fused, and the ovary is two-locular. The fruit is a subglobose capsule 4 to 6 millimeters in diameter. Seeds are brownish-black, smooth (glabrous), and approximately 2 millimeters long. This species is widespread across North America, Central America, South America, and the West Indies. In the United States, it occurs from Southeastern Virginia south to Florida, and west to Arkansas and Texas. It grows in fields, along roadsides, and in other disturbed areas.
