 Au<T.-S('pt. — Stems much branched below, 1-2-feet high. Leaves 1-2^ 

 inches long, usually obtuse at the base and closely sessile, occasionally very 

 slightly petioled, membranaceous, the margins miimtely undulutc. Cyme 

 rather few-flowered. Flowers small. Sepals obtuse or acutisl*, spreading, 

 small. Styles (sometimes 4, Ell.) distinct at the summit. — The dots in the 

 leaves of this species are reddish purple when viewed by transmitted light; 

 but in the Arkansas variety (which complete specimens may show to be 

 distinct) the dots are perfectly colorless.
