History Museum at Stockholm.' They were more completely described in a 

 later work entitled Florae Indiae Occidentalis (vol. 1, 1797; vol. 2, 1800;

Hamilton, W. Prodromus plantarum Indiae Occidentalis. 1825. Several

Grisebach, A. H. R. Flora of the British West Indian Islands. 1864. The 

 type specimens are mostly in the herbarium at Gottingen, though many are in

Urban, I. Symbolae antillanae. 1898 et seq. In this work Pilger has de- 

 scribed several grasses. An account of the grasses of Porto Rico is found in 

 the Flora Portoricensis.* The Krug and Urban Herbarium was lent in 1912-13 

 to the U. S. National Herbarium for study. In this herbarium are many 

 Bertero specimens, some the types or duplicates of types of species described 

 by Sprengel, together with collections of Rugel, Linden, Wullschlaegel, Sieber,

 in Cuba and regarding the works of Grisebach and of Wright and Sauvalle, 

 based mainly upon Wright's collections. 



The present paper is based primarily upon the study of collections 

 in the United States National Herbarium. At the end of this article 

 all these specimens are listed with their identifications. For this 

 reason the citation of specimens under each species is limited to the 

 relatively rare species. Several other important herbaria have been 

 consulted and specimens contained therein have been considered in 

 defining the range of the different species. 



Among the more important collections examined may be men- 

 tioned Wright's Cuba plants, of which the first set is in the Gray 

 Herbarium, the United States National Herbarium having a nearly 

 complete set of duplicates ; those of Brother Leon, of the Colegio de 

 la Salle, Habana, the richest single collection of Cuba grasses that 

 has been made, a practically complete set of which Brother Leon has 

 contributed to the National Herbarium; the collections of Harris
