correspond with it. But as the parts constituting the Flowers 
of Grafses are frequently very minute, we make use of the 
Botanical Microscope and the Difsecting Instruments, to dis- 
play them more clearly to the eye;* and likewise take the 
advantage of comparing them with the figures in the plate of 
Grafses. Having determined it to be an Arundo or Reed, it 
remains for us to ascertain the Species. We see that only 
four species of Arundo are natives of Great Britain; and the 
circumstances of the five Florets in each Calyx, added to the 
flexibility of the Panicle, which we had observed whilst grow- 
ing to be waved about with every wind, leave us no room to 
doubt that it is the Arundo phragmites of Linnzus, or the 
common Reed, — :

PLANTA’GO. (Plantain.) | 
The Plantain flowers in June and J uly. It is very common, 
in mowing Grafs, and on the sides of roads. It is frequently 
stuck in the cages of Linnets and Canary Birds, who are fond 
of the seeds, Upon examining a specimen of this, we find 
that each flower contains 4 Stamens, nearly of the same length ; 
therefore we refer it to the fourth Clafs. We find this Clafs 
contains 4 Orders, dependent upon the number of Pistils. 
Each of our flowers contains only one Pistil, and therefore 
belongs to the first Order, This Order admits of ten subdi- 
visions. The specimen we have, contains Blofsoms of one 
Petal ; and this Petal is fixed beneath the Germen. From 
these circumstances we look for it in the third subdivision, - 
and finding by cutting acrofs the Seed-vefsel, that it is divided 
into 2 + cells, we conclude that it is a Plantago. We now

+ To judge whether a Capsule consists of one or more Cells, the best 
method is to cut it through horizontally with a sharp knife, then care- 
fully to pick out the seeds, leaving the dividing mesnbranes entire, If it 
be very minute, cut off a thin slice horizontally, place it on the stage of 
the microscope, view it through the magnifier, and at the same time difsect 
it with the instruments,
