or calathium (HaXadiov, a small cup), is formed, as in Dandelion, 

 Daisy, and other composite plants (figs. 263 and 264) ; also in 

 Scabiosa (fig. 253), and Dipsacus (fig. 265). Such a receptacle or 

 shortened peduncle may sometimes be folded so as to enclose partially 



or completely a number of flowers (generally unisexual), giving rise to 

 the peculiar inflorescence of Dorstenia (fig. 266), or to that of the 

 Fig (fig. 267), where / indicates the flowers placed on the inner sur- 

 face of the receptacle, and provided with bracteoles. This inflorescence 

 has been called Hypanthodvum (i/*i, under, Sivhg, a flower). 



Lastly, we have what are called compound indefinite inflorescences.
