    Misionella es propuesto como un nuevo género perteneciente a la tribu Tigridieae, con relaciones estrechas alos géneros Cypella, Kelissa y Onira y vegetativamente y anatómicamente es semejante también a Herbertia.Misionella es constituido de dos especies Misionella Hauthalii y Misionella opalina (con dos subespecies:opalina y minuticristata). Misionella es endémico en los pastizales ocurrentes en el nordeste de la Argentina(provincias de Corrientes y Misiones), centro y noroeste del estado de Río Grande de Sur, en Brasil y sur delParaguay (departamentos de Itapuã y Paraguari). Misionella es taxonómicamente revisado, sus especies sondescriptas e ilustradas en detalle y su distribución geográfica es representada en mapa. Son fornecidos dadossobre etimología, distribución geográfica, hábitat, fenología, conservación, usos y nombres vernáculos, ademásse discuten las relaciones taxonómicas de Misionella con sus taxones afines. Una clave dicotómica para lasegregación de los géneros de Iridaceae-Tigridieae ocurrentes en Sudamérica es propuesta.

    It is proposed the new genus Misionella belonging to the tribe Tigridieae. Misionella is closely related to thegenera Cypella, Kelissa and Onira, and vegetative and anatomically also resembles Herbertia. Misionella isconstituted by two species, Misionella Hauthalii and Misionella opalina (with two subspecies: opalina andminuticristata). Misionella is endemic on grassland areas occurring in northeast Argentina (Corrientes andMisiones provinces), center and northwestern Rio Grande do Sul state, Brazil and southern Paraguay (Itapuãand Paraguari departments ). The genus Misionella is taxonomically revised, and its species are described andillustrated in detail and its geographic distribution is represented on a map. Data on etymology, geographicdistribution, habitat, phenology, conservation, uses and vernacular names are provided, as well as discussionsof taxonomic relationships of Misionella with related taxa. A dichotomous key for distinguishing the genera ofIridaceae-Tigridieae from South America is presented.
