Mr. G. C. Nealley, who has made a thorough exploration of 

 Western Texas, has discovered several new species, among which 

 are Triodia Nealleyi^ of similar aspect to 7! avenaceUy and another 

 Triodia of which, unfortunately, too little for full characterization 

 was collected and which may be called T, repens ; also Bouteloua 

 stricta, 2-3 feet high, with rigid, erect culms, and panicle of 4-6 

 short, appressed spikes; Stipa Jlexuosa^ di species resembling^. 

 avenacea, but distinct, with larger panicle, longer and more capil-
