The following synonyms, all named by Ciferri (using epithets provided by Pohl as the basionym)
were not, to our knowledge, based on the examination of specimens of Pohl, but were based
on materials from the Dominican Republic. Ciferri did not cite any specimens, and we have
not found any specimens either annotated by him, nor collections made by him.
5Throughout the monograph, we employ the convention of the acronym followed with a dash
and a number to indicate that number of specimens in the herbarium.
