I think the small leaves you see in the picture do not belong to the pink spike. On the right upper corner you can see what I think are the typical red/orange flowers of Gesneriaceae.
As per Passiflora... no way... that's not a Passiflora!
Bromeliaceae is stil my top candidate for this spike... but... who knows... as said before, pictures of leaves and/or whole plant would help a lot!
