THE BELLADONNA FAMILY. 263 



must be first observed, to distinguish any members 

 from the Lily family. The perianth may be in six 

 separate leaves or coherent into a tube. The six stamens 

 will be adherent to the tube, with introrse anthers, 

 never extrorse as in Irideoe. In some genera with a 

 polyphyllous ' perianth {i.e. with free perianth leaves), 

 the stamens are free from the perianth tube, and are 

 epigynous. 



The fruit is usually a capsule, or sometimes a 

 berry. 



Hseman'thus. — This genus has its very small flowers 

 massed into a large head surrounded by brightly 

 coloured bracts, thereby imitating a single flower ; but 

 an examination of one of the tiny flowers reveals the 

 structure as identical in main features with all other 

 members of the family, which differ in the lengths of 

 the tube and border, how they are expanded, etc. 



Some genera have the stamens connected by a 

 petaloid band, called a corona. This is seen in Pan- 

 cra'tium. It is very characteristic of the English 

 Daffodil, in which it forms a long trumpet ; but in the 

 Poet's Narcissus, it is reduced to a little purple rim. 



Amaryl'lis Belladon'na. — This plant gave the name 

 to the order and one tribe. It is the only species of 

 the genus ; it has just a slightly curved perianth, with 

 not much difference in the size of the leaves ; but it 

 well illustrates another adaptation to insects in having 

 the stamens and style declinatc, or lying down in front.
