A taxonomic revision of Bursera subgen. Bursera in the Greater Antilles and the Bahamas, including a new species from Cuba

A revision of Bursera in the Greater Antilles and the Bahamas has confirmed that Commiphora does not occur in the region and that all but one species in the region belong to Bursera subgen. Bursera . Here we describe a new species, Bursera yaterensis ; B. nashii is synonymized with B. glauca and B. ovata is synonymized with B. trinitensis ; and we return five species from Commiphora to Bursera . A dichotomous key is provided using mostly vegetative characters due to the frequent lack of adequate reproductive material and the relative uniformity of most floral and fruit characters.
