It resembles members of the Meliceae in its closed leaf sheaths, truncate, scarious lemma apices, and chromosome base number, but lacks the distinctive lodicule morphology of that tribe. Some features support its inclusion in the Poeae. The lodicules are similar to those found elsewhere in the Poeae, and the closed leaf sheaths are not uncommon there. Chloroplast DNA data also support its placement in the Poeae (Soreng et al. 1990). The scarious glumes and prominently 3-veined lemmas are unusual in both the Poeae and Meliceae, but are also found in Cutandia of the Poeae. One species is native to the Flora region.</p> |tables= |references={{Treatment/Reference |id=soreng1990a |text=Soreng, R.J., J.I. Davis, and J.J. Doyle. 1990.
