They are warm growing hard-cane Dendrobiums. Look up Phal. Type Dendrobiums on the net for culture advice.

It took me a second to recognize it! The orientation of the photo made it look almost like Epidendrum porpax!

Thanks! Now I can figure out what to do with them.

They're just bare rooted in a big bowl. just pointed the phone down a snapped a pic. I found them in the trash of a plant rental business, there were a few dozen of them. I just grabbed a handful.
