CORRECTIONS AND EMENDATIONS. 



r>^.R.T i. 



No. 5. Setaria mu data, second line, Plant annual. The drawing represents a 

 perennial form or species common in western Texas, Arizona, New Mexico, and 

 northern Mexico. There is, however, a closely related form which is annual. 



No. 11. Hilar ia mutica Benth. It should be stated that this is Pleuraphis 

 mutica Buckley. Mr. Bentham united the genus with Hilaria, and according to 

 the views of some botanists Buckley's name should follow the species in paren- 

 theses; thus, Hilaria mutica (Buckley) Bentham. 



No. 15. Elionurus, plate 15. The specific name at the bottom of the plate 

 should be barbiculmis. 



Plate 19. Andropogon hirtiflorus Kth. The figures a and b do not well repre- 

 sent the glumes of the species. It is probable that by mistake the drawings were 

 made from spikelets of A. scoparius. The first empty glume should be represented 

 as narrow and acuminate at apex, with the back scabrous-roughened and hairy. 



Plate 23. Aristida divaricata H. B. K. This is Aristida Humboldtiana Trin. 

 Trinius excludes A. divaricata as a mixed and uncertain species. 



Plate 27. Epicampes macroura Kth. I was misled by the specimen in the 

 United States Herbarium (No. 1973 C. Wright's New Mexican Coll.) in naming 

 this species. Evidently it is not E. macroura Kth., which has a dense, cylindrical 

 spicate panicle. It is- Epicampes ligulata Scrib. Fournier in Enumeratio Mexi- 

 canarum Plantarum enumerates 13 Mexican speCies of Epicampes, of which we 

 have too little representation to determine if our plant is among the number. 



Plate 28. This is the Cinna macroura of Thurber in the Botany of California, 

 but not of Kth. 



Plate 29. Ohloris elegans H. B. K. is believed to be a synonym. 



Plate 32. This is Eustachys glauca Chap. That genus being now united to 

 Chloris, it becomes C. glauca (Chap.) Vasey. 



Plate 45. Bouteloua striata. It should have been stated that this species was 

 collected by G-. C. Nealley in western Texas. 



Plate 47. The figures 1 and 2 in the plate should be transposed, No. 1 being 

 the female plant, No. 2 the male plant. 



Plate 48. Eremochloe. This name, or one too close to it, viz, Eremochloa 

 Buse, is one of earlier date for a different genus; and Professor Hackel has named 

 our plant Blepharidachne.
