GRAMINACE/E. 



[Endogens. 



'1'he value of some of the generic distinctions upon which botanists have hitherto 

 relied is seriously disturbed by the curious discovery made by M. Esprit Fabre 

 that /Egilops is merely the wild form of Triticum, that is to say, of cultivated 

 Wheat. 



The supposed poisonous qualities of certain Grasses has become more doubtful 

 than ever. It is certain that Bromus catharticus is a nonentity, FeuilleVs figure, 

 on which this species has been founded, being made up of Br. secalinus and some 

 purgative Iridaceous rhizome (Medic, and (Econom. Bot. p. 27 )■ And the noxious 

 qualities of Darnel or Lolium temulentum seem to rest upon no certain proof. 

 That formidable list of mischief, belonging to its seeds, of which Haller says so 

 much, resembles what might be expected of some ergotised Grass. At all events 

 the properties of Darnel should be made the subject of renewed inquiry.
