of four bracts in opposite pairs. The Mallow (figs. 225, 227) has, outside the five-fid 

 calyx, a caljcule of three bracts, and the Marsh Mallow one of six to nine bracts. 



The five green bodies beneath and adherent 

 to the calyx of the Strawberry (fig. 228), and which 

 alternate with the five sepals, are .not a calycule 

 of bracts but of pairs of stipules belonging to the 

 sepals. The pitted cup with fringed margins which 

 encloses each flower of the Scabious (figs. 223, 220) 

 may be considered a calycule. 



Calycules are true one-flowered involucres, ana- 

 logous to the many-flowered involucres of heads 

 and umbels. 



The following are also one-flowered involucres : 

 the three foliaceous cut bracts of Anemone (fig. 230), 



placed far below the 

 calyx ; the three entire 

 bracts of llepatica (fig.

 below the calyx; the 

 many foliaceous bracts
