This member of the Malvaceae family was given this name by Joseph Nelson Rose in 1905. It is found in the Sonoran Desert, Mexico and Honduras growing in a well drained soil with lots of sun. The trunk can grow to one meter in diameter, and reach for twelve meters in height. The large flowers are from white to yellow, and the plant is said to be produced by seeds only, although I have succeeded with cuttings. The genera name is from the local languish; Taíno: ceyba for kapok. The species name means 'pointed leaves'. It does grow into a rather slim tree.
