Diagnostic features:— Drypetes alba subsp. latifolia is distinguished from the other species in Cuba and the Caribbean by the presence of an asymmetrical fruit ( Figure 1A–C ), vs. symmetrical in the rest, only similar in the type subspecies, which differs from this by the position of the stigma regarding the ovary, being sessile in D. alba subsp. alba and subsessile in D. alba subsp. latifolia .

Taxonomic notes:— Grisebach (1865) recognized two infraspecific taxa within Drypetes alba : D. alba var. alba and D. alba var. latifolia , with the description of the new variety. Subsequently, in the latest taxonomic approach to the genus in the New World, Levin (2013) stated that D. alba var. alba grows in Hispaniola, Puerto Rico and the U.S. Virgin Islands, whereas D. alba var. latifolia grows in Cuba, Jamaica and a few Lesser Antilles ( Antigua, Guadeloupe, Martinique and Barbados). These varieties are distinguished by the absence or presence of a short style to bear the stigma of the female flowers, respectively ( Müller 1866, Levin 2013). However, due to both entities have their own vicariant areas, the appropriate status to treat them is that of subspecies and the new combination is here provided.

Lectotypifications:—The material C. Wright 1927 at GOET (#3380), lectotype of Drypetes alba subsp. latifolia doesn’t have a collector’s label that matches the 9 types described by Howard (1988). However, by analyzing the information available on the sheet label, it is possible to rule out some of them, either by locality, collection date or label color. That is why only those materials of C. Wright 1927 with the labels type 7 and 8 according to Howard (1988) are considered possible isolectotypes of this name.

Müller (1866) based Drypetes glomerata var. olivacea on the C. Wright 1929 material, however he only addressed the whole collection without naming the herbarium where it was deposited, making every material of this collection the syntypes of the name. Later on, Levin (2013) proposed that the “ holotype ” of this name was found in G-DC herbarium, a designation that cannot be considered effective lectotyping given the lack of the phrase “designated here” or an equivalent, which is necessary for this purpose as of 1 January 2010. In addition, in G-DC, there are three sheets in existence with that collection number. Between G-DC #325942, G-DC #325943 and G-DC #325944, the latter has annotations on the labels referencing the work of Grisebach (1865), which matches the protologue of the name and, therefore, here we designated it as lectotype.

Distribution:—Endemic to the Caribbean. Native to Cuba, Jamaica and Lesser Antilles ( Antigua, Guadeloupe, Martinique and Barbados). In Cuba, it is found in the provinces Pinar del Río, Artemisa, Matanzas, Villa Clara, Sancti Spíritus, Camagüey, Holguín, Santiago de Cuba, Guantánamo and the Isla de la Juventud special municipality, in mesophyllous semideciduous forest, mesophyllous evergreen forest, gallery forest, sub-montane rain forest, xeromorphic thorny thicket on serpentinite soils, xeromorphic sub-thorny thicket on serpentinite soils, coastal and sub-coastal xeromorphic thicket, anthropic savannas and mogotes vegetation complex, with an elevation between 25- 800 m ( Figure 2 ). The record of this taxon in Villa Clara province corresponds to Castañeda-Noa (2008) in Mogotes de Jumagua (materials not seen).
