A Lepanthes stem, blooming without having its leaf

This is how an inflorescence of a Lepanthes woodburyana looks

A stem, producing flowers without a leaf.  I had never seen this in Lepanthes 

I have seen many Lepanthes woodburyana in el Yunque forest.  But it is the first time I have seen a stem producing flowers without the having a leaf.  Interestingly it is the first time I have ever taken a photo of a Lepanthes from the back of the flower.
