The characters of this group require careful consideration. Many gynobaseous plants 

 have a calyx imbricated in a similar way, but they are removed by their gynobasic 

 structure. The imbricated character of the calyx depends upon this ; that the whorl of 

 floral leaves is broken, so that about two of the sepals are out of the place of the others, 

 and are, consequently, altogether external. 



The Calycose passes into the Parietose group by Turnera, and into the Syncarpous by 

 Hugoniaceae.
