Description

Family Rutaceae

The Rutaceae are herbs, shrubs , and trees with glandular punctate , commonly strongly smelling herbage comprising about 150 genera and 1,500 species that are further characterized by the common occurrence of spines and winged petioles . The leaves are alternate or opposite, simple or palmately or pinnately compound , or sometimes heathlike or reduced to spines; stipules are absent. The flowers are often sweet-scented, nearly always bisexual , and are actinomorphic or sometimes zygomorphic. The calyx consists of 3-5 distinct or basally connate sepals and the corolla consists of 3-5 distinct or sometimes connate petals or rarely the petals are lacking. The androecium consists of distinct or sometimes connate stamens that are commonly obdiplostemonous , that is in two whorls with the outer whorl opposite the petals. However, sometimes there may be (1)3-4 whorls or rarely up to 60 stamens. The gynoecium consists of a single compound pistil of commonly 2-5 or more, often incompletely connate carpels that may be united only basally or apically, either one or an equal number of styles , and a superior ovary with usually 2-5 or more locules, each bearing 1-several axile ovules. Generally, an intrastaminal nectary disk is situated between the stamens and the ovary. The fruit is variable. -- Gerald Carr.
