• Discussion

  The following species of Eragrostis have not been identified and the types have not been examined: Eragrostis alba Presl, Rel. Haenk. 1: 279. 1830. Described from Monterey, Calif. The type specimen at the National Museum, Prague, is labeled " Regio montana." It appears to be E. virescens Presl of Chile. Scribner " examined a duplicate in the Bernhardi Herbarium at the Missouri Botanical Garden, and referred it doubtfully to E. pastoensis. Poa olmedi H. B. K. Nov. Gen. & Sp. 1: 159. 1816. "'Crescit in montibus Peruanis et Loxae ad vias, juxta domum botanici hispani Don Vicente Olmedo." This is a species of Eragrostis which, from the description, may be the same as E. montufari. Doctor Lecomte informs me that the type specimen cannot be found in the Paris Herbarium. Eragrostis tristis Jedw. Bot Archiv Mez 5:205. 1924. "Bolivia, ad Huancapamba (Pflanz nr. 359). Quechisla (Bender nr. 19) ; Peruvia. prope Tacna (Meycn)." From the description it may be E. nigricans. Eragrostis villamontana Jedw. Bot. Archiv Mez 5: 197. 1924. "Bolivia, prov. Tarija, ad Villamontes (Pflanz nr. 632)." Eragrostis stenoclada Presl, Rel. Haenk. 1: 278. 1830. Published from mountains of Peru but the locality corrected in the Addenda to Monterey, California. The specimen in the National Museum at Prague is labeled " Luzon." It is E. elongata (Willd.) Jacq.
