The musciform Selaginella species with broad lateral leaves, which form a well defined group, are revised for the West Indies. Six species are recognized, of which three localised endemics of Cuba are described as new to science: S. undata, from the mountainous southeastern region (Nipe-Sagua-Baracoa Massif, Holguín, Santiago de Cuba and Guantánamo provinces), S. cristalensis, restricted to the Sierra Cristal (Holguín and Santiago de Cuba provinces), and S. orbiculifolia, only known from the Alturas de Trinidad (central Cuba, Cienfuegos and Sancti Spiritus provinces). Illustrations for and a key to all six species are provided.
