THE PLANT AND ITS PARTS, 9 



green Calyx, composed of five little pointed pieces 

 called the Sepals. Then follows the yellow Corolla of 

 five Petals. Observe that they are alternate in position 

 with the sepals. Next come two sets of Stamens, one 

 set of five being shorter than the other set. Each 

 stamen consists of a thread-like stalk, or Filament, 

 bearing a two- chambered Anther at the top. These 

 two chambers, or Anther-cells^ contain a powder called 

 Pollen. The continuation of the filament between the 

 two cells is called the Connective. 



In the middle of the flower is the green Pistil. 

 This is composed of five Carjpels, which are united 

 below into a bag-like Ovary. In this will be found 

 five chambers, called the Ovary-cells, each containing 

 two rows of Ovules, which are destined to become Seeds. 

 The projections upon which the ovules are situated are 

 called the Placentas. Above the ovary arises a rod-like 

 structure called the Style, which branches near the top, 

 each branch terminating in a knob-like Stigma. 



Such are the parts of the five Floral Whorls. In 

 most fiowers there are only four whorls, but Ox'alis 

 cer'nua happens to have two whorls of stamens instead 

 of one only, as is usually the case in flowers. 



In addition to the actual parts of a flower making 

 up the floral whorls, there are contrivances for secreting 

 honey. These are knobs called Glands on the Floral 

 BeceiJtaclc, the name given to the enlarged end of the 

 flower-stalk, or pedicel.
