GRASSES OF MICHAUX’S FLORA BOREALI-AMERICANA. 148 
Andropogon saccharoides 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. oce.”” is Pennisetum setosum (Sw.) Rich. as 
described in Grisebach’s Flora. Leeke refers this to Pennisetum indicum (Murr.) 
Kuntze.@ 
Poa glutinosa Sw. Prod. 26. 1788. 
The type specimen from Swartz in herbarium Casstrém at Stockholm, marked 
“e Jamaica” is Eragrostis glutinosa (Sw.) Trin., E. sudans Grisch. 
Poa prolifera 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 Hragrostis 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 Muséum 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.
