My understanding is that the bulge just above the node is referred to as "ventricosing". When my B. oldhamii culms get some size to them, they will have this bulge and also will my Bambusa textilis.

I have seen the compressed internode on D. strictus... just one out of 20. I have also seen it on B. Bambos... about 3 of 20. Neither had any pattern like first internode above the first node. The picture of two side by side is definitely unique. On the D. Strictus, the compressed internode caused a "fork" where two branches were opposite each other. The B. Bambos compressed internodes were usually close to the base with no branches.
Here's a D. asper with 3 compressed nodes together.
