32. Bouteloua heterostega (Trin.). 
Heterosteca juncifolia Desv. Nouv. Bull. Soc. Philom. Paris 2: 188. 1810, not Bou- 
teloua juncifolia Lag. 1816. In 1813 Desvaux @ reduces this to a synonym of Heter- 
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 Linnean 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.

Dineba juncifolia Beauv.; Steud. Nom. Bot. ed. 2. 1: 510, 1840. A name only 
given as synonym of Futriana 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 Muséum has both wide 
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.6 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 
Dinebra chondrosioides H. B. K. 
Bouteloua porphyrantha Wright, Anal. Acad. Cienc. Habana 8: 201. 1871; Sauv. FI. 
Cub. 192. 1873. The type isa part of Wright 739. Duplicates of this number and of 
the other specimens cited by Grisebach, Wright 734 and 3816, are well represented in 
a Journ. de Bot. 1: 68. 1813. 
bH. B. K. Nov. Gen. & Sp. 1: 173. pl. 64, 1816.
