ESSENTIAL ORGANS \ ^^ Flower 



When a flower consists of four parts; namely, calyx, corolla, andrcecium^ 

 and gynoecium, as in the Kabura and Sakura, it is said to be Complete. 



When a flower wants one or more parts, as in the Jinchoge and Shidare- 

 yanagi, it is said to be Incomplete. 



When each part of a flower consists of an equal number of constituents; 

 or the constituents of one part are multiples of those of another, as in the 

 A inn, (Linum usitatissimum) and Kirinso (Sedum kamtschaticum), the 

 flower is said to be Symmetrical. 



When each part of a flower consists of an unequal number of constitu- 

 ents or the constituents of one part are not multiples of those of another,, 

 as in the Keshi and Mume, the flower is said to be Unsymmetrical. 



HYPSOPHYLLARY LEAVES OR BRACTS. 

 The Hypsophyllary Leaves or Bracts are modified leaves 

 situated below the flower or flowers. They are developed 

 either singly as in the Tennansho (Fig. 53) and Ayame, or 

 in whorls as in the Ichirinso (Anemone nihoensis) (Fig. 98)- 

 and Eiunogiku (Chrysanthemum sinense, var. japonicum) 

 (Fig. 99). In the former case, they are said to be Scattered,. 

 and in the latter, Verticillate.
