Andropogon fasciculatum (L.) Thellung. 463 
Let us examine further the history of the names Agrostis radiata 
L. and Andropogon fasciculatum L. Agrostis radiata was transferred by 
Swartz!) to his new genus Chloris and Andropogon fascieulatum Linn. 
was cited as a synonym. But there is no reason to think that Swartz 
had any more knowledge concerning A. fasciculatum than we have at present. 
The first collection of West Indian plants that came to the attention 
of Linnaeus was sent from Jamaica by Patrick Browne. These plants 
were described in a small pamphlet by Elmgren?) Some of Browne's 
plants appear to have been the types of certain added species in the tenth 
edition of the Systema Naturae. In- this work appears Agrostis radiata, 
but Andropogon fasciculatum is not mentioned. Somewhat later?), in an 
article entitled „Flora Jamaicensis*, appears under Andropogon in the list 
of grasses, but without description. „6 fasciculatum 364*. This refers to 
the sixth species of Andropogon described on page 364 (error for 365) by 
Patrick Browne‘). This is evidently not Agrostis radiata (Chloris radiata), 
as shown by the description, by the Sloane citation (which refers to 
Paspalum virgatum) and by the fact that Agrostis radiata is described by 
Browne on page 137 and appears to be well understood. 
In a later work?), Linnaeus describes Andropogon fasciculatum, using 
the same diagnosis as in the first edition, the same synonym from 
Morison, adds the citation from Browne mentioned above (Andropogon 
6, page 365), and replaces the original queried citation from Sloane 
(t. 65, t. 2) by another (t. 69, f. 2) which refers to Paspalum virgatum, 
There is nothing in any of this history to connect the name „fasciculatum“ 
with an American specimen. 
Taking all things into consideration I think there is no evidence 
that Chloris radiata Swartz is a synonym of Andropogon fasciculatum L. 
In the second edition of the „Species Plantarum“ Linnaeus retains the 
latter name but he also describes Agrostis radiata (Chloris radiata Swartz) 
which is based on a Browne plant in the Linnaean Herbarium. So far 
as this evidence is worth anything it does not support the idea that 
Linnaeus considered these the same species. 
Of course, Chloris fasciculata Thellung, being based on Andropogon 
fasciculatum L. is a typonym of that species, and the application of the 
former name depends upon the identity of the Linnaean species. Ac- 
cording to the „American Code of Botanical Nomenclature“®), Chloris 
fasciculata Thell. is invalidated by C. fasciculata Schrad., which is said 
by Döll to be a synonym of C. distichophylla Lag.
