Flowersia is a rather widespread genus with at least four species; two species present in the Neotropics. In the tropical Andes on soil or soil covered rocks, rarely epiphytic; high open montane and montane forest to páramo and puna. Characteristics of this genus include the absence of a hyalodermis, single papillae centered over the subquadrate cell lumen, wrinkled, not furrowed capsule and absence of a peristome characterize the genus. Flowersia was previously treated as species of Anacolia by Flowers (1952), and recently as Bartramidula by Fransén (1988). The generic name honors the United States bryologist Seville Flowers (1900-1968).

En los Andes tropicales sobre suelo o rocas cubiertas por suelo, rara vez epífita; montano alto abierto y bosque montano hasta páramo y puna. Las características de este género incluyen la ausencia de hialodermis, papilas simples centradas sobre el lumen celular subcuadrado, cápsula no acanalada, arrugada, y sin peristoma. Flowersia fue previamente tratada como una especie de Anacolia by Flores (1952) y recientemente como Bartramidula por Fransén (1988). El nombre genérico hace honor al briólogo Seville Flowers (1900-1968) de Estados Unidos.

Dioicous. Perichaetia terminal or appearing lateral by innovations; leaves slightly longer or twice as long than stem leaves. Setae short, 1.5-8.0 mm long, curved. Capsules suberect, urn subglobose, 3-4 mm long, wrinkled; opercula convex-plano; peristome absent. Sporescoarsely papillose.
