This is a creeper, inhabiting the shores in the bay of Rio Janeiro. Its stem is herbaceous, rounded, covered with short and rather stiff hairs. Its leaves are simple, opposite, gradually tapering to a short channeled petiole adhering to that of the opposite side, and forming tufts at certain intervals whence arise adventitious roots. They have a smooth, trapezoid, coarsely intended limb. The flowers form little axillary heads, with from 15 to 20 flowers each, arising from an involucre with five divisions and supported by a somewhat filiform pedicle. Calix tubulous, monophyllous, with five teeth, and much shorter than the tube of the corol. The corol is monopetalous, of a yellowish white, tubulous, puffed up at its extremity, with five reflexed divisions, and five stamens with bilocular, connivent anthers which are longer than the corol. Ovary one-celled, flat at the top, whence proceeds a slender style, terminated by a glandular stygma which is longer than the stamens. Fruit monospermous, elongated, with a crustaceous integument which is covered with a number of stiff hairs that are bent over, and which presents irregular longitudinal furrows. The root is perennial and ramose. We employ the leaves.
