Abstract
Two new species of Anthurium endemic to Rio de Janeiro, southeastern Brazil, are described. Anthurium cronembergerae and A. sakuraguianum occur in humid areas in the Atlantic Forest. Descriptions and illustrations are provided, together with commentary on geographic distribution, ecology, flowering and fruiting phenology and conservation status. Comparisons are made with other similar Brazilian species of Anthurium section Urospadix, to which the two new species are assigned.
