CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 



Lagasca in the herbarium at Munich and one from the herbarium of the Botanical 

 Garden at Madrid, bearing this name in Lagasca's hand, spikelets of which are before 

 me, possibly should go with B. filiformis. It seems impossible to identify it. It has 

 been commonly assumed that Bouteloua bromoides Lag. was the same species as that 

 named Dinebra bromoides by Kunth, but Lagasca does not mention Kunth's species 

 and his description does not apply to it.

 repens. See also Spreng. Syst. Veg. 1 : 293. 1825. Founder a, uses this name, but it 

 is very certain that the specimens he cites under it do not belong here.

 Based upon Dinebra repens. The former is the first correct combination which has 

 been found, although the name was applied to a different species.
