I feel sure that this is the Cordia I saw in flower in a wood close to Corumbá in the 
month of August, and in the above description of the habit and colour of the flowers 
that belief has been acted upon. The plant referred to bore similar dense masses of 
large flowers at a time when leaves were not to be seen, a fact, unless I mistake, not 
known of other species of Cordia $ Gerascanthus.
