210 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
‘“Savannas, Retiro, July.’ In the Grisebach 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.

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 0.6 mm. 
6. Syntherisma villosa Walt. Fl. Car. 77. 1788.

There are two specimens in the Grisebach Herbarium, one marked ‘‘Edge of 
woods, bushy savannas, Hanabana, May 30,’ 1865, numbered 173, the other, “Bushy 
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. ALLOTEROPSIS Presl, Rel. Haenk. 343. pl. 47. 1830.4 
Blades elongated, 30 to 40 em. long; racemes several in a cluster.2. A. dura. 
Blades mostly radical, 10 to 15 cm. long; racemes | or 2 ....---- _l. A. amphistemon. 
« 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 Allote- 
ropsis semialata (R. Br.); Panicum sem ialatum 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 
pairof 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.
