EUPHORBI ACEiE. 
Euphorbia ocellata, nova species. Herba csespitosa depresso-ascendens glabra, fronde ccm- 
planata, nodis tumentibus. Folia opposita oblique arcuateque cordato-ovata unaque cum 
petiolis plus minus 3 lin. longa, tertiam fere internodiorum partem sequantia, costa mediana 
superne sulcata inferne in nervum producta. Stipulae 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. Capsuke haud carinatas. 
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 
of the internodes, the exterior half of the leaf obliquely ovate, the other half acuminately- 
cordate. The middle rib arched, furrowed on the upper surface and prominent on the back. 
Stipules filiform. Involucre ovoid, 5-ribbed, about 1 line long, with shorter pedicels. Segments 
5, with laciniate ochroleucous tips alternating with as many stipitate flat glands, with an 
annular margin, and resembling an apothecium, generally ochroleucous, but sometimes purple 
in the younger involucres. Capsules not carinate. Pose creek ; August.
