Looks like you could be right, Brad. The over all coloring is lighter and more even than the decora. looks like the sheath blades match too, but I cant tell what the sheath blades look like in the pic Roy linked, and its nearly 12:30am, and Lord KNOWS I need my beauty sleep, so I will wait until later to satisfy my curiosity and scroll through the numerous images!
one Q- do all the aureasulcata forms have the same culm texture... the spectabalis is the only one I have heard that refered to, I just recently got a nice size aureocalis, and have not "felt it up" yet, and my harbin, harbin inversa, alata are all to small for me to tell. By going out and feeling the smaller culms in the grove, that could point out which are small vivax, which are aureasulcata.
Yep, Bama, you are going to have to explain to all and sundry what you are out amongst the bamboo doing....."its OK folks, Im just out here stroking my culms......"
on second thought, better do it when no one else is around......
