Sammanfattning (abstract):
Three new species of South American Randia (Rubiaceae, Gardenieae) are described and illustrated: Randia wigginsii Standley ex Gustafsson from montane tropical forests in Ecuador and Northern Peru is mainly recognized by its tomentose to velutinous corolla tube and the lanate-velutinous pedicels and fruits. The possible features of beeing unarmed and having single male flowers are discussed. Randia pubistyla Gustafsson from lowland tropical dry forests in Western Ecuador and Colombia is recognized by its puberulous style, the tomentose to puberulous fruits that usually are crowned by a calyx with reflexed lobes, and by the small thorns. Randia longifolia Gustafsson from lowland tropical humid forests in Western Ecuador is mainly recognized by its relatively large, glabrous corolla, the linear calyx lobes and by the reticulate finer vasculature on the abaxial surface of the leaves. The affinities for each species are discussed.
