CORRECTIONS AND EMENDATIONS. 
ee PART I. 
No. 5. Setaria caudata, 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. Hilaria mutica Benth. It should be stated that this is Plewraphis 
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. Hpicampes macroura Kth. Iwas 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 EL. macroura Kth., which has a dense, cylindrical 
howl spicate panicle, It is Epicampes ligulata Scrib. Pee: in Enumeratio Mexi- 
canarum Plantarum enumerates 13 Mexican species of Hpicampes, 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. Chloris elegans H. B. K. is believed to be a synonym. 
Plate 32. This is Hustachys glauca Chap. That genus being now united to 
Chloris, it becomes C. glauca (Chap.) Vasey. 
Plate 45. Bouteloua stricta. It cae have been stated that this species was 
collected by G. C. Nealley in western Texa 
Plate 47. The figures 1 and 2 in the stats should be transposed, No. 1 being 
“sg the female plant, No. 2 the male plant. 
q Plate 48. Hremochloé. This name, or one too close to it, viz, Hremochloa 
Buse, is one of earlier date for a different genus; and Professor Hackel has named 
our plant Blepharidachne.
