Descripción
Sumario:[EN]Sanguisuga caesarea, a new genus and species of Cytinaceae from Colombia and the first record of this family in South America, is described and illustrated. Sanguisuga is close to Bdallophytum but differs from it by exhibiting andromonoecia, with male flowers only at the base of the inflorescence, flowers zygomorphic, semiclosed, and dorsoventrally compressed. The tongue-shaped tepals are arched, curved inwards and include a ventral, sigmoid, nectar-secreting tepal. The elongated seeds are obpyriform with a length/width ratio of 1,5-1,8.
