DISCUSSION.— Stenandrium tuberosum has been recognized as part of the flora of Cuba (León and Alain 1957), Hispaniola ( Moscoso 1943; Liogier 1995), Puerto Rico ( Liogier 1997), the Virgin Islands, and the Lesser Antilles (Acevedo-Rodríguez and Strong 2012). Stenandrium rupestre was treated as a synonym by Sprengel (1825), Urban (1911), Jennings (1917), León and Alain (1957) and Liogier (1997); Gerardia portoricensis was treated as a synonym by Liogier (1997). The holotype of G. portoricensis was annotated by Emery C. Leonard as S. tuberosum in 1931.
