 by some authors as a distinct genus, but which, despite their opinion, 

 cannot easily be distinguished from /f/Jj/jertia," the androceum is 

 restricted to one side of the receptacle, and the gynseceum, 

 which at first occupied its top, is hence thrown to one side. The 

 perianth is as in the cyclandrous HihherticB. Thus, in the flower of

 five petals alternate with these, imbricated, or more rarely contorted

3 We have observed (Oj). cif., 130) that the 

 formation of this bundle begins by a single 

 nipplc-sliapcd swelling, nearly central, but 

 somewhat nearer petal No. 5, than the others.
