Diagnosis. — Cinchonal Eocogens, with epipetalous stamens, straight anthers, bursting longitudinally, didymous fruit, and verticillate leaves without stipules.

Herbaceous plants, with whorled leaves, destitute of stipules, and angular stems. Flowers minute. Calyx superior, obsolete, or 4-5- or 6-lobed. Corolla monopetalous, valvate, rotate, or tubular, regular, inserted into the calyx; the number of its divisions equal to those of the calyx. Stamens equal in number to the lobes of the corolla, and alternate with them. Ovary peltate or 2-celled ; ovules solitary, erect ; styles 2 ; stigma simple. Fruit a didymous, indehiscent pericarp, with 2 cells and 2 seeds. Seeds erect or peltate, solitary ; embryo in the axis of horny albumen ; radicle inferior ; cotyledons leafy.

There can be little doubt that the inconspicuous weeds of which this Order is composed, have as strong a claim to be separated from Cinchonads, as that Order from Caprifoils. It is true that no very positive characters are to be obtained from the fructification, but the want is abundantly supplied by the square stems and verticillate leaves without stipules, forming a kind of star, from which circumstance the name Stellate is derived.
