About Tripterocalyx micranthus (Torr.) Hook.
Tripterocalyx micranthus is an annual herb with an overall compact, erect, and branched growth form. Its red stem is hairy, glandular, sticky in texture, and reaches a maximum length of about 60 centimeters. Each leaf consists of a fleshy, hairy green blade that can grow up to 6 centimeters long, borne on a long petiole. Its inflorescence is a head of several elongated flowers: each flower grows from a long, glandular pedicel, and all pedicels attach to a small central receptacle. Individual flowers are trumpet-shaped, pink or green-tinged, and can measure up to 1.8 centimeters long, with a corolla face up to half a centimeter wide and 4 or 5 lobes. The fruit has wide, thin, net-veined or ribbed wings extending out from its central body. This species is native to prairies, meadows, and fields.
