32. Bouteloua heterostega (Trim). 



Eeterosteca juncifolia Desv. Nouv. Bull. Soc Philom. Paris 2: 188. 1810, not Bou- 

 teloua juncifolia Lag. 1816. In 1813 Desvaux a reduces this to a synonym of Het er- 

 osteca americana, but he was not justified in so doing according to our present concep- 

 tion of species. Kunth & appears to have interpreted Desvaux correctly and figures 

 the plant so common in the western portion of the island of Cuba, but made the mis- 

 take of including with it Aristida americana L. Desvaux's original description of 

 the genus Heterosteca would exclude the Linnsean plant. 



? Bouteloua juncifolia Lag. Gen. & Sp. Nov. 5. 1816. It seems impossible to deter- 

 mine what this is. Lagasca does not mention Desvaux and it does not appear prob- 

 able to me that he and Desvaux had the same species. Lagasca's type comes from a 

 region to the north of the known distribution of Bouteloua heterostega as here inter- 

 preted.

 given as synonym of Eutriana juncifolia. 



Bouteloua humboldtiana Griseb. Mem. Amer. Acad. n. ser. 8: 532. 1862. (PI. 

 Wright. Cub.) The type is Wright 734 in the Grisebach Herbarium. Number 739 is 

 also mentioned. Wright 739 in the herbarium of the Paris Museum has both w?de 

 and narrow spiked forms on the same sheet. The species is the wide-spiked form 

 typical of Heterosteca juncifolia Desv., of which Kunth gave good figures. & Both 

 numbers are from the island of Cuba. Duplicates of both numbers as well as of 

 Wright 3816 (described as a different species) are in the Gray Herbarium. This should 

 not be confused with Chondrosium humboldtianum Kunth, which is based upon 

 Binebra chondrosioides H. B. K. 



Bouteloua porphyrantha Wright, Anal. Acad. Cienc. Habana 8 : 201. 1871; Sauv. Fl. 

 Cub. 192. 1873. The type is a part of Wright 739. Duplicates of this number and of 

 the other specimens cited by Grisebach, Wright 734 and 3816, are well represented in 



o Journ. de Bot. 1 : 68. 1813.
