do not descend to the base of the palea. It is perhaps this structure which 
has induced Palisot de Beauvois to consider it as an awn, but it is by no 
means fragile at the point of junction with the palea, and something of the 
sort may be traced in some species of Festuca.

These are united among themselves, and separated from others by the in- 
florescence, the spiculæ being many-flowered, sessile, or very nearly so, on 
opposite sides of a channelled and toothed rachis, each tooth being the recep- 
tacle of one or more spiculæ, which is received in the channel above. The 
exceptions are in Hordeum and some species of Elymus, where the spicule 
are only one-flowered, and in Triticum Nardus and T. unilaterale, where the 
spike is one-sided. I should not be very averse to joining these plants with 
Festuca, only that I cannot well separate them from J. Poa and T. tenellum. 
The latter has sometimes a branched spike, which, however, is not one-sided, 
The union of these two deviations from the type of the tribe, 
rachis and one-sided inflorescence, has led

Gaudinia fragilis is, Y think, the only plant among those which form the sub-
