FLOWER CALYX, COROLLA, AND STAMENS. Ill 



The calyx and corolla are together called the 

 perianth * ; but the word is more particularly used 

 to signify either calyx or corolla, when a flower 

 has not got both but only one of them. 



Sometimes, however, you find an extra calyx 

 close under the first one. Such a second calyx 

 is called a caliculus (little calyx) or epicalyx.f You 

 can see it in the strawberry (Fragaria), or common 

 cinquefoil } (Fig. 94): and when you 

 have an opportunity compare also 

 the flowers of the common mallow, 

 and the garden hepatica. These 

 extra calyx leaves are considered 

 to be sometimes stipules (p. 99) 

 of the sepals, sometimes involucral 

 bracts (p. 103).

 really leaves : and so also are the stamens and the 

 pistil. You must therefore add another to the kinds 

 of leaves you have already learnt about. There are 

 not only foliage leaves, and scale leaves, and bract 

 leaves, but also flower or floral P leaves, those of the
