&quot; is given honoring the Dominican botanist Alberto Veloz, who is the Head and Curator of the Herbarium JBSD of the &quot;Dr. Rafael M. Moscoso&quot; National Botanical Garden of Dominican Republic. For 27 years, Veloz has dedicated his life to the study of the Hispaniolan flora and has conducted extensive fieldwork across the island, with many collections from the Sierra de Bahoruco, where this new species was found. Together with other botanists he has collected over 10,000 specimens and has published several papers on the flora in national and international journals. His publications have included different approaches, such as floristics, taxonomy, ecology and conservation. Veloz has also contributed to the formation of young botanists by involving students as part of the staff in the herbarium JBSD and through fieldwork.

based on further field work and demographic study. However, based on the currently known limited distribution of the species, the few numbers of individuals that have been observed, as well as anthropogenic activity near populations of the species, we consider that this species could be Near Threatened based on IUCN criteria. Further fieldwork will be essential for providing a comprehensive assessment of the conservation status of

. Fortunately, the larger population known for this species is within the Sierra de Bahoruco National Park, so it is mostly protected from large-scale anthropogenic disturbances. Furthermore, the SDTF in that area is very well developed (i.e., non-fragmented) and should provide extra protection for the species.
