DOUBTFUL SPECIES. 



In the following list are given the names of species described from 

 the West Indies, for which we have not been able to account : 



Alva gigantea Steud. Syn. PI. Glum. 1: 224. 1854. Described from a specimen 

 in the herbarium of Mougeot, said to be very likely from the Antilles. - 



Anatherum berterianum Spreng. ; Schult. Mant. 2: 443. 1824. "In Portorico 

 et Guadeloupe." Has been referred to Imperata, but the description does not 

 well apply. 



Anatherum pedunculosum Desv. Opusc. 70. 1831. "Antillis." Possibly An- 

 dropogon condensatus. 



Avena lutea L. f . Suppl. PI. 112. 1781. Trisetum luteum Pers. Syn. PI. 1 : 97. 

 1805. " Martinique." The description does not apply to any species known 

 from the West Indies. 



Cenchrus hirsutus Spreng. Neu. Entd. 3: 15. 1822. " Hispaniola." The de- 

 scription does not agree with any species known to us from the West Indies. 



Cenchrus parviflorus Poir. in Lam. Encycl. 6 : 52. 1804. Described from Porto 

 Rico. Probably Chaetochloa geniculata, but the description does not well apply. 



Chaetochloa corrugata parviflora Scribn. & Merr. U. S. Dept. Agr. Div. Agrost. 

 Bull. 21: 24. 1900. Based on Cenchrus parviflorus Poir. The species to which 

 this name is applied is Chaetochloa geniculata, 



Chondrachijrum scabrum Nees; Steud. Syn. PL Glum. 1: 288. 1854. Described 

 from " Ind. Occ." but the locality possibly erroneous. The description suggests 

 Melica, which is not known from the West Indies. 



Digitaria (?) doming ensis Roem. & Schult. Syst. Veg. 2: 475. 1817, based on 

 Panicum domingense Zuccagni.
