Galeate (Helmet-shaped), Pappilonaoeous (Like a Cruciate (Like a Cross), 

 Monk's-hood. Butterfly), Sweet Pea. Cuckoo-flower. 



Within the corolla are placed the " stamens " (male repro- 

 ductive organs) these consist generally of two parts, the 

 head and stalk, the former called the "anther" and the 

 latter the " filament," which last is sometimes absent, and 

 the anther is said to be "sessile;" on the surface of the 

 anther is the "pollen" or fertilising dust. 



Within the centre of the flower is the "pistil" (female 

 reproductive organ), this consists of one or several cells 

 called " ovaries," from the pistil a tube rises, having an 

 expanded end called the " stigma," it is by the application 

 of the pollen-dust to this stigma that the ovaries are fertilised, 

 and the various insects, especially bees, who seek for honey, 

 shake off by their movements the pollen from the anthers 

 and cause it to be applied to the stigma, thus unconsciously 

 performing a neccessary office for the plant while they rob 

 it of that only which is not required. 



The stamens are sometimes separate, sometimes bound up 

 into one or more bundles, and are placed in various situations, 

 names are given to describe such arrangements as follows : 



Stamens in one bundle, Monadelphous. 



Stamens in two bundles, Diadelphous. 



Stamens in more than two bundles, Polyadelphous. 



Filaments placed directly below the pistil, Hypogynous. 



Placed upon the sides of the calyx, Perigynous. 



On the sides of the corolla, Epipetalous. 



On the top of the ovary, Epigynous.
