Dinebra secunda Roem. & Schult. Syst. Veg. 2 : 711. 18] 7. Based upon Cynosurus 

 secundus Pursh. 



Dinebra verticillata Wight; Steud. Syn. PI. Glum. 1 : 209. 1854. A name cited as 

 synonym of Leptochloa wightiana. It is from India and probably not a member of 

 this group. 



Enteropogon melicoides Nees; Steud. Syn. PI. Glum. 1:216. 1854. A manuscript 

 name published as a synonym of Eutriana enteropogon. 



Erucaria Cervantes, La Naturaleza (Mexico City) 1 : 347. 1870. There is no way 

 of determining with any certainty what the species described are, and consequently 

 they must be rejected. It is not certain that all of the species belong to this group. 

 Cervantes proposed the following names: Erucaria glandulosa, E. villosa, E. hirsuta, 

 E. lutescens, E. monostachia, E. tetrastachia, E. longifolia, and E. glabra. Fournier 

 .has suggested that E. glabra is B. curtipendula. The description of E. glandulosa and 

 E. hirsuta both suggest B. hirsuta. Erucaria lutescens and E. monostachia suggest 

 B. procumbens or B. scorpiodes. Erucaria villosa may be B. chondrosioides . Erucaria 

 tetrastachia may be B. gracilis. 



Eutriana antillarum Steud. Syn. PL Glum. 1 : 217. 1854. Based upon "Aristida 

 antillarum Lam . ' ' 



Eutriana ? chloridea Kunth, Enum. PL 1 : 280. 1833. Based upon Dineba chloridea 

 Presl. 



Eutriana Jcarwinsldana. Steud. Nom. Bot. ed. 2. 1 : 620. 1840. A name only, from 

 Trinius's manuscript. 



Eutriana ledebourii Trin. Gram. UnifL 238. 1824. Although citing Dinebra secunda 

 j/k Roem. & Schult. (Cynosurus secundus Pursh) as a synonym, Trinius gives the habitat 

 as St.- Domingo. A specimen named E. ledebourii in the Trinius Herbarium, is 

 doubtful. The spikelet is that of a Bouteloua, but the spikes have but a single spike- 

 let. It does not seem probable, then, that this is the same as B. americana, but I am 

 not able to decide without more material. 



Eutriana melicoides Steud. Syn. PL Glum. 1 : 216. 1854. The first synonym cited 

 is an East Indian plant. 



Eutriana villosa Steud. Nom. Bot. ed. 2. 1 : 620. 1840. No description is given, and 

 the synonyms are only manuscript names. 



Ischaemum melicoides Koenig; Willd. Sp. PL 4 2 : 941. 1806; Steud. Syn. PL Glum. 

 1: 216. 1854. Steudel cites this name as a synonym of Eutriana enteropogon. The 

 plant is from India and probably does not belong in this group. 



Leptochloa arabica Kunth, Rev. Gram. 1: 91. 1829. Based upon Dinebra arabica 

 Jacq. 



Pappophorum alopecuroideum Vahl, Symb. Bot. 3 : 10. pi. 51. 1794. Thi3 has been 

 referred tc Bouteloua megapotamica, but Vahl's figures show it to be true Pappophorum. 



Tripogon bromoides Roth, Nov. PL Sp. Ind. Or. 79. 1821. The generic description 

 excludes Bouteloua; Roem. & Schult. Syst. Veg. 2 : 600. 1817. An earlier mention 

 of the name based on Triathera bromoides Roth in manuscript.
