Oxalis rugeliana is a species of wood sorrels from the Oxalidaceae family. It is found in Cuba, Dominican Republic, Haiti and Puerto Rico.
It resides in montane rain forests at low elevations.
It was first described in 1912 by German entomologist, Ignatz Urban as Oxalis domingensis. However, in 1943, its status as a separate species was rescinded and considered to be a variety of Oxalis corniculata â i.e.: Oxalis corniculata var. domingensis. Since 2012, it has been restored back to its previous status of being a separate species.
