NATURAL FAMILIES.

such a manner as to form a head ; the anthers are separate, the 
filaments are connected at their sides, and this latter circum- 
stance, together with the papilionaceous form of the corolla, 
places the clover in the class Diadelphia. 
Most of the Syngenesious flowers are composed of two sorts 
of florets, either tubular with a toothed margin, or strap shaped, 
appearing flat like a strap, hut being also toothed at the edge ; 
these are sometimes called Semi-florets, or half flowers. 
Three sections are made upon the consideration of these dif- 
ferent florets. 
1st. Semi-flosculovs flowers, which are entirely composed of the 
strap shaped or ligulate florets, the dandelion and lettuce 
are examples of this section ; these are all of one colour. 
2d. Flosculous flowers, such as are entirely composed of the 
tubular florets, as the thistle and saffron ; these are also 
of one colour. 
3d Section comprises those flowers which are composed of 
both tubular and strap shaped Jlorets, the disk or middle 
consisting of tubular florets, and the ray or border of the 
flat florets. The colour of the disk and ray is often differ- 
ent in the common Daisy ; the disk is yellow, the rays are 
white. 
As the Syngenesious flowers are more difficult to analyze 
than any others except the Cryptogamous plants, we will assist 
you with a drawing of one of these plants. 
ANALYSIS OF THE DAISY. 
We have here a representation of the mountain daisy ; as we 
have the whole plant before us, we will in regular order consid- 
er the appearance of all its different parts. 
1. The Hoot : you will observe this answers to the general de- 
scription of fibrous, having the small thread-like parts issue 
from the main root, or radix : from these fibres sometimes 
spring out little tubercles, so that it may be said to be fi- 
brous tubercled. 
2. The Leaves you observe, spring from the root, and are hence 
called radical ; being also undivided, they are therefore sim - 
pie. In form they are somewhat oval, with the narrow end 
towards the stem ; this form is called obovate. The leaves 
are said to be crenate, on account of the notches upon their 
margin. 
3. The Stem is called a scape, because it springs directly from 
the root, and bears no leaves ; it is said to be naked, having 
no kind of appendages.
