GKASSES OF MICHAUX's FLOKA BOEEALI-AMERICANA. 143 



Andropogon saccharoid.es Sw. Prod. 26. 1788. 



There is no specimen of this from Swartz at Stockholm, but at Munich there is a 

 specimen sent by Swartz and marked "prodr." It belongs to the species described 

 under this name in Grisebach's Flora. 



Andropogon fastigiatum Sw. Prod. 26. 1788. 



The type specimen from "Jamaica, Swartz" belongs to this species, as described 

 in Grisebach's Flora. 



Andropogon brevifolium Sw. Prod. 26. 1788. 



There is no specimen of this at Stockholm from Swartz, but. at Munich there is a 

 sheet of specimens from Jamaica sent by Swartz and marked ' ' prodr. ' ' This is partly 

 A. brevifolium as generally understood and as described by Swartz, and partly A. 

 leucostachys H. B. K. In the absence of other evidence we may consider the Munich 

 specimen as the type, excluding the portion which is A. leucostachys. 



Cenchrus setosus Sw. Prod. 26. 1788. 



The type specimen marked "fl. ind. occ." is Pennisetum setosum (Sw.) Rich, as 

 described in Grisebach's Flora. Leeke refers this to Pennisetum indicum (Murr.) 

 Kuntze. a 



Poa glutinosa Sw. Prod. 26. 1788. 

 • The type specimen from Swartz in herbarium Casstrom at Stockholm, marked 

 "e Jamaica'' is Eragrostis glutinosa (Sw.) Trim, E. sudans Griseb. 



Poaprolifera Sw. Prod. 27. 1788. 



Swartz's type of this is not in his herbarium, but there is a specimen marked "No. 

 17 Poa prolifera Sw. Carthagena Ins. Manzanillo, Febr. 1826 Billberg" which may 

 be a compared specimen, as it is in the Swartz herbarium. It is Eragrostis prolifera 

 (Sw.) Steud. as described in Grisebach's Flora. This is the same as Sloane's specimen 

 mentioned under Gramini tremulo affine, etc., and illustrated in his plate 71, figure 1. 



THE GRASSES OF MICHAUX'S FLORA BOREALI-AMERICANA. 



The plants collected by Andreas Michaux in North America in the 

 latter part of the eighteenth century, which form the basis of his 

 Flora Boreali-Americana published in 1803, are deposited in the 

 herbarium of the Museum d'Histoire Naturelle at Paris. 



The species are here considered in the same sequence in which they 

 -occur in Michaux's work. Following the name of the species as 

 published is the habitat as given upon the label accompanying the 

 corresponding specimen in the herbarium. The herbarium contains 

 the types of all except Dilepyrum aristosum Michx., Poa crocata 

 Michx., and Poa pectinacea Michx. Richard distributed some of 

 Michaux's plants to other herbaria. Many of these duplicates are 

 found*"" in the herbarium of Drake de Castillo at Paris. As will be 

 seen from the notes accompanying certain species in the following 

 list, it has not always been easy to determine which is the type 

 specimen, especially in the critical species of Panicum. In certain 

 cases the plant differs slightly from the description, or is from some 

 other locality than the one cited. These cases are considered upon 

 their merits in the notes accompanying each species.
