Plantarum, as well as Reyger and Moench. The two latter I 
have not consulted. Pollich’s synonym is doubtful, because he 
describes the awn of the lowermost floret as springing from the 
top of the glume, that of the next from the back, and those of 
the third and fourth florets, if there be more than three, which 
"often happens, from the base. I find them all: nearly terminal. 
This author, though an accurate observer, affords a lamentable 
example of want of botanical philosophy, as well as neglect of 
the Linnean rule, respecting natural genera, which I have often 
had occasion of late to mention, in saying that the above dif- 
ferences in the insertion of the awns might perhaps serve to 
mark this grass as a new genus. | "his circumstance ought rather 
to have taught him, that the insertion of the awn is not infal- 
Jible as marking a genus at all; on which subject I havealready, 
in the 4th volume of our Transactions, ventured to offer some 
hints, proposing the strongly fringed or pectinated inner glume 
sas a much better generic mark of Bromus. For this reason I 
cannot but consider the plant now before us as a Festuca, its 
inner glumes being finely downy at the edge, as in that genus, 
- not fringed, nor are the awns always inserted below the c 
Sométimes they are as perfectly terminal as in any Festuca. 
_ The synonym of Haller, “ Bromus pauiculá. lava, diui: quia 
= d ifloris, brevissimà aristatis, Hall. Helv. No. 1511,” is adopted by 
Reichard, on the authority of Moench, but it is pointed out by 
the suggestion of Haller himself. His description, | however, par- 
ticularly the short awns, and his quotation of Scheuchzer, t. 5. 
f- 18, as well asof Ray, evidently belong rather to Festuca ela- 
tior. I should without scruple have rejected Haller’s synonym, 
but for a specimen in Mr. Davall’s herbarium, gathered by his — 
friend Mr. Du Cros, and marked ** Bromus, H. 1511, var. minor, 
longis aristata.” This’ specimen is Bromus Ee Probably
