410. 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.

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.
