History Museum at Stockholm. They were more completely described in a 
later work entitled Florae Indiae Occidentalis (vol. 1, 1797; vol. 2, 1800; 
vol. 3, 1806). The grasses were mostly from Jamaica, 
Hamilton, W. Prodromus plantarum Indiae Occidentalis. 1825. Several 
grasses are described, mostly from specimens in the herbarium of Professor 
A. N. Desvaux. 
Sagra, R. de la. Historia fisica polftica y natural de la isla de Cuba. Vol- 
umes 9 to 12 are devoted to botany, the grasses being described by Richard in 
volume 11 (1850). 
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 
the Kew Herbarium. Many Cuban grasses are described in his Catalogus 
plantarum cubensium (1866).?\ In his “ Vegetation der Karaiben”* there is an 
annotated list of the grasses of the Lesser Antilles.

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. 8. 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, 
and others.

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 Leén, 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 Leén has 
contributed to the National Herbarium; the collections of Harris
