A nomenclatural study of Plumeria (Apocynaceae: Plumerieae) in the Caribbean Islands

Abstract An update of the nomenclature 49 Caribbean Island‐occurring taxa Plumeria (Apocynaceae: Plumerieae) is presented. We designate lectotypes for following 29 names: alba var. jacquiniana , P. apiculata barahonensis beatensis berteroi biglandulosa confusa cuneifolia dictyophylla discolor domingensis gibbosa inaguensis jaegeri jamaicensis krugii leuconeura longiflora marchii obtusa laevis parviflora ostenfeldii paulinae pilosula revolutifolia stenopetala angustissima subsessilis and trouinensis . A neotype assigned to bahamensis epitypes are presented stenopetala. portoricensis regarded as an uncertain name. Fifteen Cuban endemics were inadvertently lectotypified; three them ( cayensis cubensis stenophylla ) require a two‐step lectotypification, which here. Two names filifolia tuberculata lectotypified in previous works we concord with these typifications. The protologue magna includes holotype this
