Bursera, named after the Danish botanist Joachim Burser (1583-1639), is a genus with about 100 described species[2] of flowering shrubs and trees varying in size up to 25 m (82 ft) high. They are native (often for many species endemic) to the Americas, from the southern United States south through to northern Argentina, in tropical and warm temperate forest habitats.
