In The Garden: Colombian plant identification

The attached photo was taken in Los Katios National Park in northwestern Colombia. Any help in identification would be appreciated.

 

Do those leaves belong to the flowers? The flowers look like Aechmea ramosa, but the leaves are wrong for that.

 

Reminds Palicourea to me.

 

Here's a convincing photo of that, that the photographer included in a Weed Ecology Book group on Flickr. It's also in a Colombian plants group. Rubiaceae family.

Hi, Wendy. Most definitely NOT a bromeliad. But thanks for your interest!

 

I think this looks promising! Thanks!

 

Now we're talking, Wendy! Many thanks for the photo. Delighted to have a family and genus-level ID!
