Strange Spike?

[Optimist]

Blc. Copper Queen (Toshie Akoi X Bl. Richard Mueller) A Lowes rescue bag baby is giving me her first flower this year, but has an odd spike. She is a Cattleya alliance orchid and is giving me an oncidium like spike with no sheath like the other Blc.s I have.

Do you think this is a Brassovola thing? Do Brassovolas have sheaths? I do not have any Brassovolas or anything.

Copper Queen is a very healthy plant, so I am not worried about health. I have never seen a sheathless Cattleya. Is that a common thing?

Here's a picture. I cannot see any sheath. The two buds on one stem just come from the bifurcation of the leaf.
