Mtdm. Curriosities - Looking for answers

[Houston]

The plant pictured is a MTDM Ruffles scent of a woman. Had 3 flower spikes, growing 2 new p-bulbs, seems to be happy as it had 3 flower spikes, 2 of which were in bloom for over a month, the 3rd never produced flowers.



My first question pertains to the leaf on new growth, it has light and dark patches in it, any thoughts?

In the 2nd photo, there is another bulb growing off the top of another bulb and is actually sending out a root as well. I heard this was common in oncidiums, figured someone might like to see what it looks like.

Again in the 2nd photo, a flower spike has bloomed that originated from the top of another bulb (this happened after the other flower spikes had passed)



The first flower spikes originated from the base of the bulb and grew to about 1' in height. This flower spike is about 4 inches high, has anyone seen this happen before?
