210 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 



"Savannas, Retiro, July." In the Qrisebach Herbarium there are two specimens 

 from Wright. One collected in 1865 and numbered 178, and 294 ("var. eriogona"); 

 the other without number, labeled "Roads and fields, common, Hanabana, May 21." 

 Lamarck's type, labeled "Asperella digitaria lam. ill. ex. D. Richard," is in the 

 Lamarck Herbarium in the Museum at Paris. 



5. Syntherisma simpsoni (Vasey) Nash, Bull. Torr. Club 25: 297. 1898.

 Isle of Pines, Curtiss 521. 



Spikelets glabrous, 2.5 mm. long, the glume and sterile lemma equal and slightly 

 exceeding the fruit. Syntherisma aequiglumis (Hack. & Arech.) (Panicum aequi- 

 glume Hack. & Arech. in Arech. Gram. Urug. 93. 1894) differs in having larger spike- 

 lets, 3.5 mm. long, the acuminate sparsely pubescent glume and sterile lemma exceed- 

 'ing the fruit by 0.5 mm. 



6. Syntherisma viUosa Walt. Fl. Car. 77. 1788.

There are two specimens in the Grisebach Herbarium, one marked "Edge of

 savannas, Hanabana, May 27," 1865. Spikelets about 2 mm. long; plant pubescent 

 or nearly glabrous.

In the Grisebach Herbarium is a Wright specimen from eastern Cuba, 1859, num- 

 bered 1541. 



Steudel's type from "Ins. Guadaloupe Duchaissing" is in the Museum at Paris. 



26. ALIiOTEROPSIS Presl, Rel. Haenk. 343. pi. 47. 1830.« 



Blades elongated, 30 to 40 cm. long; racemes several in a cluster. 2. A. dura. 

 Blades mostly radical, 10 to 15 cm. long; racemes 1 or 2 1. A.ixmphistemon. 



a The type species is A. distachya Presl (op. cit. 344), which is published as coming 

 from Monterey, California, but the type in the National Museum at Prague has two 

 labels, "Peruana montana, " and "Regio montana Luzon?" The plant is AUote- 

 ropsis semialata (R. Br.); Panicum semialatum R. Br. Prod. 192. 1810, the type of 

 which is from New Holland. This is not an American species and Presl's type must 

 have come from the Philippines, as indicated by Scribner (Rep. Mo. Bot. Gard. 

 10: 37. 1899). Presl's plate and description are incorrect in that the artist incor- 

 . porated in the drawing of the spikelet of Alloteropsis a spikelet of an Andropogon 

 which had become wedged between the glumes and this is described as a second 

 pair of spikelets. Although Presl's genus is founded upon a misconception there is no 

 doubt as to the identity of the type species. Hence Alloteropsis, the oldest name 

 for this group as segregated from Panicum, is accepted for the genus.
