THE STUDY OF ROTANY. 17 
" succeeded by a Berry containing 4 Seeds. Looking therefore 
ta the Genus Ligustrum, in this volume, we compare it with 
the generic description, and have the satisfaction to find it 
agree with that. Being now pretty certain of the Genus, we 
look forwards to the Species, and as there is only one Species, 
‘we soon determine that it must be the Ligustrum vulgare of 
Linnzus, or the common Privet. 
EXAMPLE ff, ’ 
ARUNDO. (Reed.) 
Upon the banks of rivers, in wet ditches, and upon the 
borders of pools the Reed is sufficiently common. It is a 
sort of large grafs, five or six feet high, and flowers in June. 
. Having gathered.a specimen of this, we proceed to examine it 
systematically. At first sight we observe that the Flowers 
grow in panicles, and that each Flower contains 3 Stamens. 
“We therefore turn to the beginning of the third Clafs, and find 
that Clafs divided into three orders, which depend upon the 
number of Pistils.* Each of our flowers contains 2 Pistils, 
which brings us to the Order Digynia, This Order is subdi- 
vided into four parts. The Ist subdivision contains the plants 
with Flowers scattered, or irregularly disposed, one only in 
each Calyx. Our plant agrees with the first circumstance, 
but not with the last, for we find jive flowers in each Calyx. 
The 2d subdivision contains only 2 flowers in each Calyx ; 
therefore we pafs that over, and come to the 3d, with scat~ 
tered flowers, and several in each Calyx. Before we proceed 
further, we just look at the 4th and last subdivision, but find- 
ing those flowers in form of a Spike on a long and slender 
Receptacle, we immediately recur to the 3d subdivision. This 
subdivision contains 6 Genera, and we compare the Characters 
of each with the plant in hand. The want of an Awn, and the 
woollinefs at the base of the blofsoms, determines us to call 
it Arundo. Turning therefore to the Genus Arundo, we com- 
pare it accurately with the Generic description, and find it 
* N.B. Once for all, let it be observed, that the ‘Student should 
“Clafses, until he be perfectly acquainted with the constitution of each, 
and the exceptions which are most likely to involve him in difficulties.
