MANUAL OF THE GRASSES OF THE WEST INDIES Ls 
There is a slight uncertainty in the application of the name Milium 
paniceum. The original description apphes to the species described 
above. ‘The amplified description” also applies with the exception of 
“Raches 3- -quetrae, margine membranaceae.” ‘The rachis is only 
minutely margined. There is no specimen of Miliwm paniceum in the 
Swartz Herbarium, but there are three specimens sent by Swartz to 
other herbaria, one at Munich, one at Madrid, and one in ‘the DeCan- 
dolle Herbarium. All these specimens are Digitaria panicea as here 
understood. The habitat given by Swartz is ‘dn aridis sabulosis 
Jamaicae australis.’ This species resembles D. filiformis of the United 
States under which name Grisebach* and Nash* include it, but 
differs in having longer, more numerous racemes, longer folded or 
subinvolute blades, and slightly larger spikelets with longer pubes- 
cence.
