Chase — Notes on Genera of Panicets. IV. 



Paspalus tener Nees, Agrost. Bras. 32. 1829. This herbarium name is 

 given as a synonym of P. dissitiflorum Trin. 



This species is represented in the National Herbarium by Glaziou 15637, 

 from Brazil. 



Axonopus bijugus (Steud.). 



Lappagopsis bijuga Steud. Syn. PI. Glum. 1 : 112. 1854. (^ee above 

 under Lappagopsis. ) 



This more delicate species with smaller spikelets is represented in the 

 National Herbarium by the following, all from Brazil: Burchell 5886, 

 7703; Gardner 21178. 



Two species described by Nees, Paspalum canaliculatum and P. fasti- 

 giatum, the types of which, both collected by Martius in Brazil, were 

 examined in the Munich Herbarium, belong in this section but being 

 insufficiently known are not here transferred. 



15. Genus REIMAROCHLOA Hitchc. 



Reimarochloa Hitchc. Contr. Nat. Herb. 12:198. 1909. "For 

 R[eimaria] acuta and its allied species the above name is proposed with 

 Reimaria acuta Fliigge as the type: Reimarochloa acuta (Fliigge)" Hitchc. 



Besides the type, two other species are 

 here included in this genus, Reimarochloa 

 brasiliensis (Spreng. ) Hitchc. and Reima- 

 rochloa oligostachya (Munro) Hitchc. 

 For the discussion of Reimaria Fliigge see 

 this name under Paspalum. 



Description. — Inflorescence of few to 

 several slender racemes, approximate at 

 the summit of the culm, spreading or re- 

 flexed at maturity ; spikelets strongly 

 dorsally compressed, lanceolate, acumi- 

 nate, solitary, rather distant, subsessile 

 and alternate in two rows along one side 

 of a narrow, flattened rachis, the back of 

 the fertile lemma turned toward it ; both 

 glumes wanting (or the second glume 

 sometimes present in the terminal spike- 

 let); sterile lemma about equaling the 

 fruit, sterile palea obsolete ; fruit scarcely 

 indurated, the lemma faintly nerved, 

 acuminate, the margins inrolled at the 

 base only, the palea free nearly half its 

 length. Stoloniferous perennials with 

 linear leaves; a small genus of but few species confined to the tropics and 

 subtropics of the western hemisphere. 



The scarcely indurated, acuminate fruit, the margins of the lemma in- 

 rolled at the base only, the palea free for its upper half, and the absence 

 of the glumes, taken in combination, together with the spreading or
