Rueplant

Rue (Ruta graveolens), the type of the large order Rutaceae, a native of the south of Europe, commonly cultivated in England, is a shrubby plant, two or three feet high, with pinnately divided bluish-green leaves, beset with glands containing a powerfully smelling oil, and with corymbs of yellowish flowers. The calyx consists of four persistent sepals; there are four distinct petals, eight or ten stamens of unequal length, and four carpels united into a stalked four-chambered ovary with a single style.
