Notes on L. (Convolvulaceae) in Cuba and neighbouring islands with a checklist of species found in Cuba.

An updated checklist of species of L. found in Cuba is presented with analysis of the different elements represented. Griseb. is defined broadly to include Griseb. and Urb. and its differences from the little-known (House) Urb. are discussed. C. Wright ex Griseb. is reinstated as the correct name for the species generally known as House. C. Wright is recognised as a distinct species from A. Rich. and images are provided to help distinguish the two species. Urb. and Alain are shown to be conspecific with Choisy, whose disjunct distribution is mapped and discussed. The little-known Hadač is described and illustrated and the cited collections show it to be locally common in the Guantánamo region. J. R. I. Wood & Scotland is described as new from Camagüey in central Cuba. Eight species endemic to Cuba collected by Ekman and described by Urban in 1924 - 25 are evaluated but only two, Urb. and Urb., are deemed to warrant recognition as distinct endemic species. The origin and typification of Hook. are discussed and an epitype designated. Cultivated plants named occur in many tropical countries including Cuba but their extreme variation suggests hybrid origin. Four species from Jamaica, House, Urb., Proctor and the Jamaican plant called are treated as synonyms of a variable , which is endemic to the island. Proctor is treated as var. J. R. I. Wood & Scotland of Jacq. Griseb. is treated as a synonym of M. Martens & Galeotti. Lectotypes are designated for , C. Wright, Meisn. and Urb.
