Spikelets glabrous or minutely pubescent, tbe hairs of

In North America Axonopus proper is represented by the following 

 species : 



Axonopus compressus (Sw.) Beauv. 



Milium compression Sw. Prod. Veg. Ind. Occ. 24. L788. "Jamaica; 

 India occidentalis." No specimen of this could be found in the Swartz 

 Herbarium, but the later detailed description of Swartz (Fl. Ind. Occ. 

 1 : 183. 1797) leaves no room for doubt. 



Paspalum platicaulon Poir. Encyc. Suppl. 5 : 34. 1S04. " Cette espece 

 a ete recueillie a Porto-Ricco, par le citoyen Ledru. (V. s. in herb. 

 Lam. )." The type has not been examined but the description identifies 

 the species. 



Axonopus compressus Beauv. Ess. Agrost. 12. 1812. Based on Milium 

 compressum Sw. 



Paspalum compressum Rasp. Ann. Sci. Nat. I. 5 : 301. 1825. Based on 

 Axonopus compressus Beauv. 



Anastrophus platycaulis Schlecht. ; Ind. Kew. 1 : 118. 1893. Based on 

 Paspalum platycaule. 



Closely related to this species is a narrowerdeaved form with nearly 

 obtuse spikelets and usually few racemes which may be Paspalum tri- 

 stachyon Lam. (Tabl. Encycl. 1 : 176. 1791. "Ex America merid. Com- 

 munic. D. Richard"). This name has been referred by Trinius and 

 others to P. platycaule, but Lamarck's description " spicis ternis " points 

 to the other form. The type has not been examined. 



Axonopus furcatus (Fliigge) Hitchc. 



Paspalum furcatum Fliigge, Cram. Monog. 114. 1810. "Carolina. 

 Bosc. Walne." The type has not been examined, but the description 

 identifies the species. 



Paspalum digitaria C. Muell. Bot. Zeit. Id : .">24. 1861. "America 

 septentrionalis, ubi forsan in Texas legit T. Drummond (coll. no. 276)." 

 The type specimen was examined in the Berlin Herbarium. 



Axonopus furcatus Hitchc. Rhodora 8 : 205. 1906. 



Michaux's name Digitaria paspalodes and several names based upon 

 it, Milium paspalodes Ell., Paspalum ellioltii Wats., Paspalum paspalodes 

 Scribn., and Anastrophus paspaloides Nash, have been misapplied to this 

 species. Michaux's type specimen is Paspalum distichum L.* 



Axonopus Rosei (Scribn. & Merr. ). 



Paspalum Rosei Scribn. & Merr. U. S. Dept. Agr. Div. Agrost. Bull. 

 24:9. f. 2. 1900. "Foothills of the Sierra Madre Mountains, between
