In Grasses of the West Indies * Pennisetum antillarum (Poir.) Desv. 
is included, the type, marked ‘‘Antilles’’, having been examined in the 
herbarium of the Botanical Garden at Florence and a fragment 
deposited in the United States National Herbarium. In 1932 C. E. 
Hubbard, of Kew Herbarium, sent us specimens of Pennisetum 
hordeoides (Lam.) Steud., from West Africa, for comparison with the 
fragment. As Mr. Hubbard suggested, the two proved to belong to 
92 Contrib. U. S. Natl. Herb. 18: 353. 1917.
