Andropogon divaricatus, Humb. et Bonpl. ex Willd. Enum. Pl. Hort. Berol. i. pp. 99 et 100 nomen 
(“sed vix descriptio, que potius ad A. jacguinianam, Willd. hb. no. 1802, H. B. K. Nov.

Soutn Mexico, between Salamanca and Guanajuato at 6000 feet (Humboldt & Bon- 
-pland), Toluca (Berlandier), Mirador (Schaffner), Santa Fé (Bourgeau, 677 pro parte),

Schaffner’s 1057, from San Luis Potosi, referred by S. Watson (Proc. Am. Acad. xviii. 
p- 174) to A. divaricata, Humb. et Bonpl., is altogether different from the plant referred 
hither by Fournier, but we are unable to decide who is: right. Aristida divaricata, 
Lagasca, Gen. et Sp. Nov. p. 3, Nova Hispania, Sessé, is a doubtful unrecognized species. 
Aristida jacquiniana, Tausch. (vide Trin. et Rupr. Sp. Gram. Stip. p. 119), syn. Aristida 
divaricata, Jacq. Eclog. Gram. p. 7, t. 6, was founded on a cultivated plant of uncertain 
origin. Cheturus divaricatus, DC. Cat. Hort. Monsp. 1813, p. 19, is probably the same 
thing, and this was also cultivated under the names Agrostis divaricata and Muehlen- 
bergia divaricata.

South Mexico, near Chalma (ex Cavanilles), Orizaba (Bourgeau, 3357; Thomas; 
Botteri). Hb. Kew. 
Fournier’s identification, which we have accepted, was made from the description of 
‘Trinius and Ruprecht.
