Chilopsis saligna D.Don
Chilopsis is a monotypic genus of flowering plants containing the single species Chilopsis linearis.
It is a shrub or tree native to the southwestern United States and Mexico. The common name is desert willow or desert-willow because of its willow-like leaves, but it is a member of the catalpa family, Bignoniaceae. It is commonly seen in washes and along riverbanks at elevations below 1800m in its range.
Ranging from 1.5 to as much as 8 meters in height, it can take the form of a shrub or small tree. The linear, curved, deciduous leaves are 10 to 26 cm long and just a few millimeters wide.
The generic name is derived from the Greek words χεῖλος, (cheilos), meaning "lip," and ὄψις (opsis), meaning "resembling," referring to the flowers. They occur in a terminal panicle or raceme, blooming in May through September. About two to four flowers at a time are open in each inflorescence. The calyx is about 8–14 mm, slightly inflated, and varying shades of purple, while the corolla is 2–5 cm, and with colors ranging from lavender to light pink. The throat and lower lip has a pattern of yellow ridges and purple lines, and the margins are crinkled. It is pollinated primarily by large bees in the family Apidae, such as carpenter bees, bumblebees, Anthophora, and Centris. The fruit is a linear pod up to 35 cm long, containing numerous winged seeds.
