I don't know much about grasses, but I thought the "beard" was a tuft 
of hairs at the base of the fruit; I have never heard of its 
synonymisation with awn.

I would make a plea for not using the positional term "ventral", 
simply because this is used in two very differet senses.  Dorsal and 
ventral used early in development  are equivalent to abaxial and 
adaxial and the more colloquial lower and upper.....  Could ventral 
be replaced by adaxial or abaxial as appropriate?

As to the pulvinus, I couldn't access the illustration for some 
reason, but it does sound a little weird.
