Descripción
Sumario:A new species of Tarigidia from Puerto Rico is described and illustrated. Additional micromorphological characters of the inflorescence and spikelets are included. This species constitutes the first report of the genus Tarigidia in the New World. Tarigidia axelrodii grows together with Anthephora hermaphrodita and Digitaria bicornis, showing intermediate characters. This species gives additional evidence to support Loxton's hypothesis that Tarigidia is derived from hybridization between Anthephora and Digitaria and also supports the phylogenetic hypothesis showing close relationships between Anthephora and Digitaria.
