| Spanish abstract | El presente tratamiento incluye una revision taxonómica de las especies de Paspalum grupo Gardneriana. Dentro de este grupo se consideran siete especies, caracterizadas por incluir plantas anuales o perennes, con espiguillas usualmente obovoides, gluma superior ausente o reducida y antecio superior endurecido y marcadamente papiloso, con papilas verrugosas en toda su superficie. Se incluye una clave de las especies, descripciones, ilustraciones y fotos de los antecios, junto con un análisis de la relación del grupo dentro del género Paspalum. Se consideran dentro del grupo las siguientes especies: Paspalum burchellii, P. delicatum, P. gardnerianum, P. nudatum, P. pictum, P. reduncum y P. subsesquiglume. Se designan lectotipos para P. burchellii, P. connectens, P. reduncum y P. subsesquiglume; P. gemmosum es sinónimo de P. subsesquiglume |
| English abstract | 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 |
