Neither Haller nor Scopoli make any mention of this grafs. According to Scheuchzer, it is common 

 in Italy and France, in dry fields, and fometimes on walls : with us it is found more frequently on the lat- 

 ter ; and though not fo common as fome of the grafles, yet it is to be found on molt of the walls about 

 London, in May and June. 



In very dry and barren fituations, the ftalks fometimes are found fimple, the panicle alfo not branched, and 

 the fpiculae, inftead of containing about eight flowers, which is the ufual number, have no more than three 

 or four: in this ftate Scheuchzer makes another fpecies of it: this alteration, from an excefs or fcantinefs 



tions in which it occurs— Information obtained from any other fource is not to be depended on.
