I think you're going to have to tell me, cuz I sure don't have a clue!
Can't wait to hear all the responses!!! Looks like some kind of a spike, but the plant has a pseudobulb and yet you've got it on the phal forum....you have stumped me.
Both photos have phalaenopsis in the foreground. Although it looks like a flower bud, the first photo is a very early inflorescence; the little leaf-like sheath will flatten and perhaps even disappear as the inflorescence lengthens. The second photo is an inflorescence that is a bit more mature. Actual flower buds are visible. Hope that the spike continues to elongate and that there is more room between the buds so the flowers aren't bunchy.
