A glabrous 



erect herb or undershrub attaining 5 or 6 ft., with the acutely angular brauohes 

 and general aspect of IL alata. Stem-leaves opposite, distinctly petiolate, 

 naiTOvv-lanceolate, regularly and acutely serrate, often above 2 in. long, the 

 floral ones alternate, gradually reduced to bracts. Flowers pedicellate, clus- 

 tered in the upper axils, forming terminal leafy thyrsoid panicles. Calyx-tube 

 acutely 4-angled, the lobes broad and short' • Petals 4, about 1 line long, 

 mucronate. Stamens 8. Styles 4, rather long; ovules 4. Fruit 3 or even 

 4 lines long, acutely 4.angled or winged, crowned by the sh^ort conmvent 

 calyx-lobes, quite smooth, the thin somewhat inflated cpicarp connected vyith 

 the endocarp by a loose network or spongy substance as in Loudonia Boei.
