3. Oplismenus hirtellus (L.) Beauv. 



Panicum hirtellum L. Syst. Nat. ed. 10. 2: 870. 1759. No locality given. The 

 type, in the Linnaean Herbarium, is from Jamaica, having been sent to Linnaeus 

 by Browne. The specimen is the upper part of a flowering culm with seven racemes 

 and two leaves, with glabrous sheaths. 



Milium undulatifolium Moench, Meth. PI. 202. 1794. A garden specimen is 

 described and Panicum hirtellum L. is given as synonym. Panicum undulatifolium 

 Ard. 1 is not mentioned. Moench's name is evidently independent of that, which 

 has been applied to an Old World species. 



Oplismenus hirtellus Beauv. Ess. Agrost. 54, 168. 1812. Based on Panicum hir- 

 tellum L. 



Orthopogon hirtellus Nutt. Gen. PL 1: 55. 1818. The name is based on Panicum 

 hirtellum L., but the plant described by Nuttall is Oplismenus setarius. In the errata 

 Nuttall changes the specific name to parvifolium (see a preceding paragraph under 

 Oplismenus setarius). 



Panicum velutinum Meyer, Prim. Fl. Esseq. 51. 1818. "In nemorosis plantationis 

 Sophienburg," Essequibo. A duplicate type has been examined in the Trinius 

 Herbarium, having been sent to Trinius by Meyer. The sheaths are pubescent. 



Oplismenus velutinus Schult. Mant. 2: 271. 1824. Based on Panicum velutinum

Orthopogon cubensis Spreng. Syst. Veg. 1: 3i7. 1825. "Cuba." The type of this c/ 

 has not been examined. 



Oplismenus cubensis Kunth, Rev. Gram. 1 : 45. 1829. Based on Orthopogon cubensis 

 Spreng. 



Panicum cubense Steud. Nom. Bot. ed. 2. 2: 255. 1841. Based on Orthopogon 

 v cubensis Spreng. 



Oplismenus chondrosioides Fourn. Mex. PI. 2: 39. 1886. "Absque loco (Liebm. 

 n. 367); Cordova (Bourg. n. 1668, Schaffn. n. 281 b.)." The first specimen cited 

 may be taken as the type. This has been examined in the Copenhagen Herbarium. 

 It has hispid sheaths. The name is on the label in Fournier's hand.
