Nice photos! I like the culm writing by Soleya. See this post (http://www.bamboocraft.net/forums/showthread.php?p=3740#post3740)
It may be a while before I can give that a try. I did manage to get a few photos of shoots this spring. They were small shoots so it was kind of difficult to get a good photo of them. Here are two photos from May 5th and May 17th, 2005.

Hi Mike, these are really nice pics, though I'm still somewhat stumped as to identifying it.

Some questions...

Did the culm sheaths have any traces of auricles at all?

Has the powdery coating below the node of the new shoot now become a strongly distinct white band below the nodes?

Is the culm surface smooth or slightly rough to the touch if you rub it lightly up and down the culm?

Are the alternating grooves on the culm where branching begins the same color as the rest of the culm?

Hi Mike,
-----------
BTW Your pics were moved for you into an album at Bamboo Flora - Is this Phyllostachys nuda? (http://www.bamboocraft.net/bamboo/showgallery.php?cat=566) If you have any more pics of this plant you can upload them to this album... or upload them into this thread.

The shoot emergence time sounds about right for P. nuda, at your location, but we need to verify that P. nuda can have oral setae on it's leaf sheaths, or maybe this could possibly be a variant? - We could call it Phyllostachys notsonuda :) )

Meanwhile we could evaluate other possible Phyllostachys candidates of which shoots emerge at about the same time as P. nuda... (considered the earliest group of Phyllostachys species shoots to emerge in northernmost / coldest climates.

Early shooting species - with green culms

Phyllostachys aureosulcata - Yellow Groove Bamboo

Phyllostachys `Alata' - Green Groove Bamboo

Phyllosatchys bissetii

All of these to some extent have leafsheath oral setae.

Hi Mike, have these pics (http://www.bamboocraft.net/bamboo/showgallery.php?cat=566) been verified as P. propinqua or still undecided?

This plant is from a different source than the one that may have come from Byron. The shoots were still too small this spring to better identify the plant. I'm hoping for some better growth this coming year. This will be its 3rd year in the ground, so it's supposed to leap, right? :)

Mark-- I just realized I didn't answer your questions above. Somehow I missed them since July. Anyway, better late than never...

1. culm sheaths had no auricles (on only pencil-thick culms)
2. no distinct white band below nodes
3. smooth culms
4. no groove coloration

The new culms turn black when exposed to direct sun, then later turn dark green. I guess this is consistent with nuda.

I suppose the plant is just too small to exhibit any tell-tale signs of its identity. I am planning to cover it with straw when single-digit & lower temps arrive, so maybe I can get a few bigger shoots to look at in spring.
