Stems spreading, round, a span long, hispid with white spreading 

 hairs. Leaves short-stalked, ovate-lanceolate, cuneate at the base, 

 slightly hairy, with a short acute point. Stipules very hairy. Flowers 

 pink, arranged in a hemispherical, terminal head, surrounded by about 

 4, ovate-acuminate, cordate leaves. Calyx hispid, with linear acute 

 ciliated segments. Corolla 3 times as long as the calyx, ventricose, 

 funnel-shaped, with 6 ovate triangular acute spreading segments which 

 are hairy at the points. Von Martius speaks highly of the excellence 

 of the root of this plant as an agreeable emetic in doses of 1 or 2 

 drachms.
