I looked at a couple of the references that Pankaj sent,and don't quite see what the structure is that they are referring to as pulvinus - it looks like a part of the internode to me, but maybe it's because I can't easily see the details of the photos.  

Please take a look at this. As shown by the authors it appears to be 
like the basal part of leaf sheath, that is attached to the culm.
