Seasonally dry tropical forests of the Greater Antilles yield a new species of the Caribbean clade of Castela, Castela plenaensis (Simaroubaceae), an endemic to the southern slopes of the Sierra de Bahoruco, Dominican Republic

We provide a phylogenetic dataset (of plastomes) with one copy (IRb) of the inverted repeat removed, and tree derived from the dataset for our paper on the description of the new species, Castela plenaensis.
