SYSTEMATIC POMOLOGY 



this assemblage of tiural leaves is the flower. The stem or axis 



which bears the flower is the pedicil. When the pedicels are two 



or more in a cluster, they 

 are borne on a common stem 

 or peduncle. The arrange- 

 ment of flowers on the pe- 

 duncle is the inflorescence. 

 The upper part of the pe- 

 duncle, upon which are ar- 

 ranged the floral organs, all 

 modified leaves, is the recep- 

 tacle or torm. Usually there 

 are four quite distinct types 

 of floral organs plainly to be 

 seen in a flower, — calyx, cor- 

 olla, stamens, and carpels. 

 The lower of the two whorls 



of floral leaves form the ccdyx, each leaf of which is a sepal. 



Closely set on the receptacle above the calyx is another whorl of

floral leaves, the corolla, each leaf of which is a petal. The third 

 whorl, within and above the corolla, is the androecium, the sepa- 

 rate parts of which are stamens. Each stamen is composed of
