Yes, you _need_ flowers, and sometimes fruits to identify most plants, 
including Echinodorus species.  If you feel confident trying to key it out 
yourself, leave the flower on the plant and gather references from the 
library and try them out.  You will be measuring small parts of the 
flower such as stigmas and ovaries.  If that is not a possibility, cut the 
inflorescence and press it along with a representative leaf (between 
newspaper and two boards or other stiff surface; lay something heavy on it 
or tie tightly with rope/cords until the plant is dry).  This still won't 
constitute a perfect specimen 'cause you won't have emersed leaves, but you 
may be able to send it to someone at a local herbarium for identification.  
Herbaria can be found in most Universities; I can help with this if you 
tell me where you live.

That is funny; don't tell my SAE's or they may put in a request for some. 
(in all seriousness though, they do seem to eat some algae - I don't have 
much and they need to eat all the time apparently, thus the supplementation 
with my favorite fine-leaved plants
