they are character wrinkles ...like the ones you get from smiling alot :)

I can't see your pic but i think that i have the same issue with some of my broms too, particularly some potted neos.
I think it is due to water stress, that is, not enough water.
Being a novice still, i had rot issues with some of my broms and read some advice a while back that basically said "if in doubt, don't water". So, unless the brom has a nearly dry tank, i havent watered. And i now notice that some of the leaves are wrinkled (and they dont go away!).
I hardly ever remember to water the 'soil mix' so i wonder if the more extensive root system in a potted plant is stressed in some way and this is affecting the leaves??

This hasnt appeared on any of my mounted broms tho' (the bulk of which have only been mounted within the last 6 months and therefore either have no root system or only a small root system and probably will only ever have a small root system, i imagine).

I guess fcbs doesn't like people hijacking their images. Can't say I blame them, I don't like it either.

Winter,

As Ozvon said it is due to lack of water, in extreme cases it is called Fluting the leaves can close together quite tightly deforming the plant like a Flute, you can use a light detergent mix to try and separate the leaves.

I have seen this occur on some Vrieseas pups that I removed too early.

Some Neo's grow naturally with the wrinkles and I find it in mostly pink one., Also plants with coriacea in their parentage

Alcanteria imperialis often shows the same characteristic.

I have wrinkles on a few pink ones. I was surprised to see wrinkles on Dean, but I don't have one, so I don't know.

This guy is starting to show some wrinkles. He's been getting lots of sunlight although I just moved him last week to give him morning sun rather than afternoon sun.

And the moral of the story is that it will also take the wrinkles on the leaves of the bromeliads away?! My Royal Cordovan will be very happy to hear that!
