The bristle (beard) of some species. 
The thread supporting the anther. 
The pouch containing the pollen. 
The farina or fertilizing dust. 
The support of the stigma. 
The tip or end of the style. 
The reproductive organ. 
N.B. — The letters to the analysis refer to the plates, except a, b, c, and o, 
which are sufficiently explained above. 
Now these terms, with their references to our figures, will, it 
is presumed, he amply sufficient to indicate the parts of a grass 
referred to, without any more minute description, as it is no 
part of our plan to dwell upon the minute anatomical distinc- 
tions, or morphological theories that necessarily belong to this 
subject, which would then be rendered an abstruse rather than 
a popular one. 
It may be well, however, just to mention that some of the 
parts in the foregoing analytical table will be absent in some 
species ; them absence or presence will afford specific characters, 
and these are further enhanced by the different details of 
different parts, as whether the valves of the glume be pointed 
or obtuse, ribbed or plain, or those of the glumel awned, 
awnless, &c., &c. 
With these notes on the organography of grasses, we proceed 
to the consideration of our next point of inquiry. 
2. The Classification of Grasses. — In treating of this 
subject, we would again repeat that our remarks have imme- 
diate reference to our native species. These we shall find, with 
the exception of three, to possess three stamens and two 
pistils. The exceptions are— 
Antlioxanthum odoratum, sweet vernal grass, stamens 2, 
pistils, 2. Hierochloe borealis, northern holly-grass, terminal 
flower with stamens 2, pistils 2, lateral ones triandrous. 
Nardus stricta, mat-grass — stamens 3; pistil 1.
