Texas torchwood was first described by Samuel Botsford Buckley in 1883 based on a specimen he collected in April 1882 near Corpus [Christi, Texas|Corpus Christi], Texas. It was initially described as Zanthoxylum texanum, but Buckley later moved it to genus Amyris.Description
It is a perennial shrub, growing to a height of and roughly the same width. The evergreen leaves are compound, with three pairs of dark green, shiny leaflets. Leaves and other parts of the plant have an earthy, citrus smell, particularly when broken or crushed. Small, cream-colored flowers grow on racemes and bloom from March until October or November. Dark purple fruits form when the flowers have been pollinated, each containing one seed. The bark is mottled and lacks Thorns, [spines, and prickles|thorns]. It is able to tolerate drought and short-term exposure to freezing temperatures.Distribution and habitat
It is found in the Tamaulipan mezquital ecoregion. In Mexico, it is abundant in Coahuila, Nuevo León, San [Luis Potosí], and Tamaulipas. It occurs in the United States only in south Texas. It is found in subtropical or tropical coastal thickets, chaparral, brush, and mesic forest understory at altitudes ranging from sea level to about.Ecology
Texas torchwood attracts hummingbirds, butterflies, moths, bees, and other pollinators. The fruits are eaten by birds, lizards, and other wildlife. Giant swallowtail butterflies lay their eggs on the young leaves of Texas torchwood and other Rutaceae species.
