Abstract	Alarista succina gen. et sp. nov. (Poaceae) is described from a single floret preserved in amber of Tertiary age originating from the Dominican Republic. The new genus is characterized by 1) a narrow winged lemma awn, 2) numerous (as many as 17) lemma nerves, 3) a lengthy rachilla internode (implying a lax spikelet), 4) sinuous-margined long cells, 5) silica cells arranged transversely, 6) stomatal subsidiaries low-domed, and 7) papillae. The epidermal features are characteristic of the abaxial leaf blade surface of members of the Bambusoideae and the fossil is placed in this group. Keywords: Tertiary grass, Fossilized resin, Greater Antilles, Hispaniola
