Two new species of Cuban Tectaria Cav. (Tectariaceae) are described: T. squamosa Riverón-Giró & C. Sánchez and T. caluffii Riverón-Giró & C. Sánchez; both are endemic to E Cuba (provinces of Holguín, Guantánamo and Santiago de Cuba). Tectaria squamosa can be distinguished by the presence of abundant scales throughout the petiole and rachis, sometimes also on the costae, and the apical segment having a pair of basal lobes in which the main vein branches from the rachis, not the costa; it is compared with T. cicutaria (L.) Copel. Tectaria caluffii can be recognized by the presence and position of bulbils (propagules) at all pinnae axils and at the base of the apical segment, and the number and width of the pinnae; it is compared with T. incisa Cav. and T. vivipara Jermy & T. G. Walker. Images of the type specimens of both new species are provided in addition to information about distribution and ecology.
