E. JoNEsrr. Annual, erect, villous ; root filiform ; stems 

 terete; brandies ascending, internodes longer tban the 

 leaves. Leaves narrowly lanceolate, acute, obliquely cordate 

 at the base, sharply serrate on both margins ; petioles very 

 short ; stipules deltoid, ciliate. Inflorescence solitary in the 

 axils of the upper leaves, appearing glomerate on the ends of 

 the young branchlets ; involucres campanulate, raised upon 

 a pedicel twice the length of the petioles ; lobes similar to 

 the stipules but smaller ; glands 4, small, green, transversely 

 ovate, concave ; appendages white, entire. About thrice the 

 width of the glands ; styles long, bifurcated to the base. 

 Capsules smoo°th, shallowly tri-siilcate ; carpels strongly 

 keeled. Seeds steel-gray, short, tumid, sharply quadrangular. 

 The facets transversely niarked by 2-3 blunt ridges, in some 

 also by a longitudinal accessory ridge causing a shallow pitted 

 appearance to obtain. Plant 26 cm. high, branches 7—17 cm. 

 long; internodes average 2-7 cm.; leaves 3 cm. and shorter, 

 2-5 mm. wide. Closely related to E. florida, Engehn. Col-
