monoecious (fl. monoid), when the male and female flowers are on the same plant (Carex,

 Mercury, figs. 201, 202); polygamous (fl. polygami), when hermaphrodite flowers 

 occur amongst the male or female (Pellitory). The general term diclinous (diclinus) 

 is applied to monoecious, dioecious, and polygamous flowers. 



THE CALYX. 



The calyx (calyx) is the whorl placed outside of the corolla and andrcecium. 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-sepalous (c. gamo- 

 or mono-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- multi-fid, when the sepals cohere about half-way up (Comfrey,
