Abstract
We provide nomenclatural and taxonomical information on the names of sixteen taxa treated by Roberto de Visiani from Egypt and Nubia (Sudan) in his 1836 work ‘Enumerazione ed illustrazione di alcune piante dell’Egitto e della Nubia con otto tavole in rame’. We designate ten lectotypes (for Chrozophora brocchiana, Convolvulus lasiospermus, Corchorus fruticulosus, Croton obliquifolium, Heliotropium brocchianum, Lithospermum obtusum, Trianthema sedifolia, Trigonella arguta, Trigonella dura, and Volkameria acerbiana), and one neotype (for Convolvulus lasiospermus).
