are arranged in such a manner as to form a head ; the anthers 

 are separate, the filaments are connected at their sides, and this 

 latter circumstance, 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 (ligulate), appearing flat like a strap, but being also 

 toothed at the edge ; the latter are sometimes called Semi-flo. 

 rets, or half flowers. 



Analysis of the daisy. 

 Fig. 97. 



We have, at Fig. 

 97, a representation of 

 the mountain daisy ; 

 we will, in regular or- 

 der, consider the ap- 

 pearance of its differ- 

 ent parts. 



1. The Root, a : yxm 

 will observe this an- 

 swers to the general 

 description of fibrous, 

 the small thread-like 

 parts issuing from the 

 main root, or radix: 

 from these fibres, some- 

 times spring out little 

 tubercles, it is then said 

 to be.fibrous tubercled. 



2. The Leaves, b, 

 you observe) spring 

 from the root, and are 

 hence called radical; . 

 being undivided, they 

 are called simple. In 

 form they are some- 



what 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, c, 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. 



Why is the clover not compound ? Describe the root, leaves and stem pf 

 the Daisy.
