HITCHCOCK GRASSES OF CUBA. 221 



Rug. 187;" the other is Wright 748 from eastern Cuba. The type collected by March 

 in Jamaica is also here. Another specimen (Wright, western Cuba in 1863) is marked 

 by Grisebach as p stenostachyum. These last two specimens appear to be the ordinary 

 form of P. divaricatum. The pubescent form can scarcely be separated even as a 

 variety. 



Hamilton's species is based on "P. bamhusoides Herb. Prof. Desv. Porto Rico." A 

 specimen so marked in the Desvaux Herbarium in the Museum at Paris is P. divari- 

 catum. The type of P. chauvinii Steud. is also in the Museum at Paris.

Wright 755, 3450, 3877 in part, 756 in Gray Herbarium; Pinar del Rio, Earle & 

 Wilson HC 1550; Herradura, Tracy 9075, Hitchcock in 1906; La Magdalena Baler 1; 

 Isle of Pines, Taylor 35. The following are in the Herbarium of the New York 

 Botanical Garden: Isle of Pines, Taylor 35, Curtiss in 1904; Madruga, Shafer 452. 



Wright's 3450 in the National Herbarium is labeled "Low savannas, Chirigote, Oct. 

 26;" the same number in the Gray Herbarium, "Pinales, Almacigos, July 26." The 

 type in the Grisebach Herbarium is labeled "In bushy savannas, Hanabana, May 

 16, " 1865. The type of Richard's species is at Paris. Grisebach has two other speci- 

 mens of this, one from western Cuba, 1863, numbered "909=3450," which is the type 

 of his P. laxum variety variegatum,'^ and the other, also from western Cuba, numbered 

 "89=3450." Wright's 755, "Pinales, San Juan de Buena Vista, Nov. 21, 1860-64," and 

 no. 756, from eastern Cuba in 1856-57, both in the Gray Herbarium, are P. exiguiflorum. 



The type of Panicum tricolor, Eggers 3978, from Fortune Island, Bahamas, was exam- 

 ined at Hackel's herbarium.

 In the herbarium of the New York Botanical Garden are the following: Santiago 

 de Cuba, Taylor 28; Baracoa, Underwood & Earle 839; Santiago de las Vegas, Van 

 Hermann 2698b. 



This appears to be a. recent introduction into Cuba, where it occurs as a weed. 

 The type specimens of Swartz's three species differ only as to size of panicle. 



The specimen in the Grisebach Herbarium is from eastern Cuba in 1859 and is 

 numbered 754. Wright's 754 in Gray Herbarium is from "Roadsides near Saltadero, 

 Aug. 4," Monte Verde, 1859. 



The published source of P. illinoniense Desv. is "America boreali." The speci- 

 men in Desvaux 's herbarium in the Museum at Paris, marked with this name in 

 Desvaux 's handwriting, is P. fasciculatum Sw. The sheet is also marked "hab. 

 Carol." The locality is clearly an error.
