-petiolis plus minus 3 lin. longa, tertiam fere internodiorum partem equantia, costa mediana 
superne sulcata inferne in nervum producta, Stipule filiformes. Involucra circa 1 lin. longa, 
pedicellis longiora ovoidea quinque-costata, quinque-dentata, dentibus laciniatis ochroleucis et 
alternantibus cum totidem glandulis margine annulari apothecia simulantibus, plerumque 
ochroleucis sed in capitulis junioribus nonnunquam purpureis. Capsule haud carinate. 
Stem cespitose, depressed, ascending, glabrous ; foliage flat and two-ranked, nodes enlarged. 
Leaves opposite, about 3 lines long including the very short petiole, scarcely one-third the length

cordate. The middle rib arched, furrowed on the upper surface and prominent on the back. 
Stipules filiform. Involucre ovoid, 5-ribbed, about1 line long, with shorter pedicels. Segments
