A new genus and species, Calderonella sylvatica (Gramineae), is described from the rain forests of Panama. Features of its spikelet morphology and leaf anatomy reveal that the affinities of Calderonella are with the centostecoid group of grasses, of which Zeugites appears to be the most closely related genus. A brief characterization of the centostecoid group is presented, as well as a key to the genera included in it, with commonts on each.
