36. Bouteloua curtipendula (Michx.) Torr. 



Chloris curtipendula Michx. Fl. Bor. Amer. 1 : 59. 1803. The type, collected in 

 Illinois, is in the Michaux Herbarium. 



Bouteloua racemosa Lag. Var. Cienc. 2 4 : 141. 1805. Lagasca cites Chloris curtipen- 

 dula as a synonym in his later paper. a 



Bouteloua pendula "H. R. M." Lag. Var. Cienc. 2 4 : 141. 1805. A garden name 

 published as a synonym of B. racemosa.

Bouteloua melicaeformis Brauss.; Hornem. Enum. PI. Hort. Hafn. 7. 1807. I fol- 

 low Roemer and Schultes, & who place this as a synonym under Atheropogon apludi- 

 oides. Only a name is listed. 



—^Bouteloua melicoides Beauv. Ess. Agrost. 40. pi. 9.J. 6. 1812. Based upon "Bout. 

 melicoides Horn." (evidently an error for "melicaeformis"). Beauvois's figures, 

 however, do not apply to B. curtipendula. They resemble more closely some species 

 of the B. procumbens group. In his private copy of the Agrostographie Beauvois has 

 written in his own hand "= Atheropogon apludioides." This name was later listed, 

 with Muhlenberg as the author, by Steudel c as a synonym of Atheropogon apludioides. 



Dineba curtipendula Beauv. Ess. Agrost. 98, 160. 1812. Presumably based upon 

 Chloris curtipendula Michx., though Beauvois erroneously cites "Melica curtipendula 

 Mich." See also DC. Cat. Hort. Monsp. 105. 1813 (where the generic name is spelled 

 "Dinebra"); H. B. K. Nov. Gen. & Sp. 1 : 171. 1816; Presl. Rel. Haenk. 1 : 292. 1830. 



Dineba melicoides f Beauv. Ess. Agrost. 160. 1812. A name only, given in the index. 



Atheropogon racemosus Roem. & Schult. Syst. Veg. 2 : 414. 1817. Based upon 

 Bouteloua racemosa Lag. 



Eutriana curtipendula Trin. Fund. Agrost. 161. 1820. Based upon Chloris curtipen- 

 dula Michx. See also Steud. Syn. PI. Glum. 1 : 215. 1854. 



Melica curtipendula Michx.; Steud. Nom. Bot. 1:91, 519. 1821. Based upon 

 Chloris curtipendula Michx. This name was earlier erroneously given by Beauvois 

 .(see_a_bove under Dineba curtipendula).

 Div. Bot. Bull. 12 1 : pi. 43. 1890; Britt. & Brown, Illust. Fl. 1 : 180./. 413. 1896; U. S.

Eutriana a ffinisILook. f. Trans. Linn. Soc. Bot. 20 : 174. 1851; Steud. Syn. PL Glum. 

 1 : 215. 1854. The original description states that this is closely allied to E. curtipen- 

 dula. Our present conception of this species would include the form described by 

 Hooker. It is said to be identical with Atheropogon apludioides, Eeterostegon curtipen- 

 dulus, and Eutriana curtipendula of Schweinitz in the Hooker Herbarium. It is based 

 upon Drummond specimens from Missouri and Texas. 



Eeterostegon curtipendulus Schwein.; Hook. f. Trans. Linn. Soc. Bot. 20 : 175. 1851. 

 A name only. 



Bouteloua curtipendula aristosa A. Gray, Man. Bot. ed. 2. 553. 1856. This is the 

 typical form in the mountains of the Southwest, but even there the awns often drop off 

 toward maturity. One can establish many varieties in any of these species if he 

 choose, but it appears better not to recognize this form as a subspecies. 



Atheropogon curtipendulus Fourn. Mex. PI. 2 : 138. 1881. Based upon Bouteloua 

 curtipendula A. Gray. Schaffner 535 and Bourgeau 2755, cited by Fournier, are in the 

 herbarium of the St. Petersburg Botanical Garden.
