is the more interesting, because its petals, distinct from the 
sepals, shew we were right in considering the tendency of 
Begonia to be towards the production of a corolla, and that 
it is consequently correctly associated in the Virus plantarum 
with Polypetalous orders; and secondly, that two or four 
being the number of the floral envelopes, when distinctly 
formed, the relationship of Begoniacee to Onagrarie is almost 
demonstrated.
