Pulvinus

[kellogge]

Hi Mary -
Pulvinus is generally a thickened structure of a stem or leaf that is  
often involved in movement.  There probably needs to be a general term  
(pulvinus - is_a plant structure) with a couple of children - pulvinus  
of petiole (found in many legumes, among others), and pulvinus of  
inflorescence branch (found in many grasses).  I think it probably  
should not be part of node, since it's not clear what it's a part of.   
Bob Schmidt has isolated some inflorescence mutations that lack the  
pulvinus, and they are just trying to characterize the pulvinus and  
those mutants in particular.
