How does one tell the difference between P. bambusoides and P. vivax. Most
photos and descriptions that I've seen appear almost identical. Anything in
particular that differentiates them apart? Thanks!

David,

I've read somewhere that the easiest way to tell the difference is to look at
the tops of the culms. Phyllostachys bambusoides is supposed to have tips that
are very upright and P. vivax is supposed to have tips that are less upright
(they weep).

I believe the other reply which says the culm wall thickness is different is
also true but unless you have both and can compare them you don't have an easy
way to say which one you have.
