THE CALYX. 



The calyx {calyx) is the whorl placed outside of the corolla and androecium. It 

 is usually simple {Wallflower), sometimes double {Magnolia, Trollius) ; its component 



leaves are termed sepals {sepala). It is poly- 

 sepalous (c. polysepalus), when its sepals are 

 wholly separate {Wallflower, fig. 8 ; Colum- 

 bine, fig. 31) ; gamo- or mono-sepalows (c. gamo- 

 or monq-sepalus), when its sepals cohere more 

 or less. 



A monosepalous calyx is partite (c. partitus), 

 when the sepals are united at the base only ; 

 and it may be bi- tri- multi-partite {Pimpernel, 

 fig. 203) ;— it is bi- tri- muUi-fid, yvhen the sepals cohere about half-way up {Comfrey,
