Panicum blepharophorum Presl, Rel. Haenk. 1:312. 1830. " Hab. in 

 Mexico." The type specimen is in Presl's Herbarium in the Bohemian 

 National Museum at Prague. 



Panicum tumescens Trin. Mem. Acad. St. Petersb. VI. Sci.JSTat. 3 2 : 316. 

 1834. No locality other than Brazil is given. In the Trinius Herbarium 

 is a specimen collected by Riedel in Bahia, Brazil, in 1831, marked by 



Trinius " Panicum tumescens 

 m . , " which is no doubt the type. 



Milium orinoccense Willd. ; 

 Steud. Nom. Bot. ed. 2. 2 : 146. 

 1841. This is given as a synonym 

 of Panicum aturense H. B. ly. 



Homolepis isocalyci((a (Meyer). 

 Panicum isocalycitfum Meyer, 

 Prim. Fl. Esseq. 59. 1818. "In 

 arenosis umbrosis continents " 

 Essequibo [British Guiana]. A 

 specimen of this sent by Meyer 

 was examined in the Trinius Her- 

 barium. 



Panicum Langei Fourn. Mex. PI. 

 2 : 23. 1886. " Teotalcingo (Liebm. 

 n. 435. junio)." The type speci- 

 men is in the herbarium of the 

 Botanical Garden of the University at Copenhagen. 



In the National Herbarium there is a specimen of H. isocalycina col- 

 lected by Salzmann in Bahia, Brazil, and distributed without number, as 

 "Panicum zizanioides H. B. K." It is distinguished from II. aturensis 

 by the slightly shorter, more turgid spikelets,. with a glabrous sterile 

 lemma and more indurated fruit.

Homolepis aturensis. 



(Two views of spikelet. fruit and sterile 



lemma x 6% diam.) 



Homolepis longispicula (Doell). 



Panicum long iflorum Trin. Mem. Acad. St. Petersb. VI. Sci. Nat. 3 2 : 

 317. 1834, not Gmel. 1796. No locality other than Brazil is given. In 

 the Trinius Herbarium is a packet of spikelets marked "Panicum longi- 

 florum m. Brasil," and a specimen bearing the same name and also "no.

Panicum longispiculum Doell in Mart. Fl. Bras. 2 2 : 261. 1877. " Hab- 

 itat in Brasilia, loco accuratius non adnotato (herb. Acad. Petropolit. ) . " 

 Doell cites " Paspalum longiflorum Trinius in Act. Petrop. 1835. p. 307 non 

 Gmelin Syst. Veg. I. 158." This must be an error for Panicum since 

 there is no Paspalum longiflorum of Trinius nor of Gmelin. The page 

 reference is also erroneous. Evidently Doell' s name is a typonym of 

 Panicum longiflorum Trin. 



Ichnanthus longiflorus Benth. Journ. Linn. Soc. Bot. 19 : 45. 1881. This 

 is based on " Panicum longiflorum Trin"., though from his statement that 

 "in /. longiflora (Panicum longiflorum, Trin.) they [the auricles] are very
