the grasses for Gay's work, cites Bertero's No. 117 under his Bromus stamineus, while 

 the other numbers do not appear to be cited at all, at least not under the genus Bromus 

 or Festuca, where one would expect to find them. Steudel does not give auy reason for 

 using the specific name he has given this plant, but the inference is that it is the popular 

 name, yet it is not among those given in the last volume of Gay's Flora. It may be a 

 diminutive of cebada, barley, grain ; though on turning to a dictionary the only English 

 equivalent of cebadilla given is " powder of hellebore " ! We suspect this is one of the 

 forms of the common Bromus unioloides. Cebadilla is the name in Central America of 

 the fruits of Schcenocaulon officinale, A. Gray, a Melanthaceous plant.
