15. Dioscorea richardhowardii Raz , nom. nov. Rajania tenella Howard (1947: 119) . Type:— CUBA. Sierra de Nipe, south of Woodfred, in dense woods with yellow flowers, 28–9 July 1941, Howard 6134 ♂ (holotype GH! (marked as “Type”), isotypes BM!, GH!, NY!, S!, US!)

Notes: Endemic to eastern Cuba. The GH sheet that is marked on the label in pen and stamped above the label as “Type” should be considered the holotype. The second GH sheet is unmarked: it is a comparatively poor specimen, discolored and somewhat degraded. This epithet honors the late Richard Howard, who was, in all senses, a giant of West Indian botany.
