Description

Menodora scabra (formerly Menodora scoparia) is broom-like shrub in the Olive Family (Oleaceae), known by the common name rough menodora or broom twinberry. It is a popular desert garden plant. It is native to the southwestern United States (Colorado, Arizona, Utah, New Mexico, Nevada, Texas and California) and northern Mexico (Coahuila, Durango, Nuevo León, Chihuahua, Sonora), where it grows in varied mountain, plateau, and desert habitat. Menodora is a genus of perennial plants and shrubs in the olive family Oleaceae. Its 23 species (as per Green 2003) are found in the temperate Americas and in southern Africa. These are uniform species of deserts and arid grasslands or savannas. The usually bisexual flowers have a united calyx with 5-10 lobes (rarely more), while the corolla is similarly united but with 4-6 lobes. The corolla is a pretty, bright yellow (except for M. spinescens, whose corollas are white), and is often scented. The fruit is a didymous, bilobed capsule with each globose locule or lobe containing 2-4 seeds. In the majority of species, each locule also features circumscissile dehiscence. Vegetatively, the plants are generally unremarkable, with a "green-stick" look that is common to many desert plants. In the dry seasons, plants may lose their generally small or reduced leaves altogether. Leaf shape within the genus is highly variable, ranging from short and linear to almost feathery and pinnatisect. Leaves are most commonly found arranged in opposite pairs, but in some individuals may be predominantly alternate.
