Revision of Paspalum group Gardneriana (Poaceae, Paspaleae). Species of Paspalum group Gardneriana are revised as a whole for the first time. Seven species are treated in this work, being the group characterized by including annual or perennial species, with spikelets usually obovoid, upper glume absent or reduced, and upper anthecium indurate and strongly papillose, with verrucose papillae all over its surface. A key to the species is provided, together with a discussion of previous infrageneric classifications and relationships of Gardneriana; morphological descriptions, and illustrations of all species are also presented. The following species are included in Paspalum group Gardneriana: Paspalum burchellii, P. delicatum, P. gardnerianum, P. nudatum, P. pictum, P. reduncum, and P. subsesquiglume. Also, lectotypes are designated for P. burchellii, P. connectens, P. reduncum and P. subsesquiglume; P. gemmosum is defined as a new synonym of P. subsesquiglume.
