DIVISION II 

 PERIANTH INFERIOR AND OVARY SUPERIOR 



Lily Family (Liliacecs). — There is great uni- 

 formity in the structure of the flowers of this 

 family. The chief differences are as follows : — 

 Since the parts of the outer whorl (calyx) are 

 coloured, as are those of the inner (corolla), 

 botanists call the whole a perianth^ as stated, and 

 its individual parts leaves. There are usually three 

 parts in each whorl, and these may be all free as 

 in a tulip, or all coherent as in the garden hyacinth. 

 Then the stamens may rise freely from the recep- 

 tacle as in a tulip ; or they may be adherent to the 

 free parts of the perianth as in the wild bluebell ; 

 or again, if the perianth have its parts coherent as 

 in the hyacinth, then the stamens are usually 

 adherent to it as in the hyacinth or Lily of the 

 Valley. 



The pistil is composed of three carpels, coherent 



from base to summit as of a tulip, and may 



become a capsule as in the flower of colchicum, or
