300. The Crown imperial, Fritillaria 
Imperialis, exhibits in the claw of each 
of its petals, a cavity called a nectary ; 
each one is always filled with a sweet 
liquid. If these drops are removed, 
others immediately take their place. You 
have here a representation (Fig. 51,) of 
Z this flower; its petals appear as if cut off, 
4) in order to show the six nectariferous 
? glands at the base of each. 
201. In the Ranunculus, the nectary 
is a production of the corolla, in the form 
of a scale ; in the violet a process of the

Stamens and Pistils. 
302. The stamens and pistils in most plants are enclosed by 
‘tthe same envelope, or stand upon the same receptacle; in the | 
‘class Monecia they are on different flowers which spring from | 
one common root; and in Diccia, they are on different flowers | 
‘springing from different roots. Yet, however distant the sta- 
mens and pistils may be, nature has provided ways by which | 
the pollen from the staminate flowers is conveyed to the pistil- 
late, to assist in perfecting the seed. That you may be better 
understand this curious process, and the organs by means of 
which it is carried on, we will examine each one separately. 
Stamens. 
303. Stamens are thread-like parts, exterior as to the pistil,. 
and interior as to the corolla. They exhibit a variety of posi 
tions, some being inserted wpon the pistil, some below it, and) 
others around it.
