8. Dioscorea hyalinomarginata Raz View in CoL , nom.nov. Rajania spiculiflora Uline ex Knuth(1917:219) .Type:— DOMINICAN REPUBLIC. “ Santo Domingo ”, no date, Poiteau s.n. (holotype B!, isotype K!)

Rajania marginata Knuth (1935: 121) . Type:— DOMINICAN REPUBLIC (“ Santo Domingo ”). Provincia Samaná: Loma Zaramagua, light forest on limestone, 200 m, 9 June 1930, Ekman 15251 ♂ (holotype B!, isotypes S!, US!).

Notes: Endemic to the Dominican Republic. In the protologue of Rajania marginata, Knuth cited in synonymy, “ex. aff. R. spiculiflorae Uline ,” but no such annotation appears on any of the material I examined. As the epithet suggests, this species is easily distinguished from others in section Rajania by its hyaline margin, especially prominent in dried specimens. The inflorescences are always arrayed in scorpioid cymules, and it is one of only three Rajania species with striate pollen.
