Phew! Thanks guys! What is it they say.... a little knowledge can be dangerous? :s
Its weird, it sort of looks like another leaf... maybe because i split the top of the new leaf dusting it?...
But your right its not coming from the centre of the new leaf... its behind it and coming from the leaf underneath on the opposite side, the same way as roots and spikes do
Ive had her 3-4years, seen endless blooms, aerial roots, and never lost a single leaf... but ive never seen anything come out of the crown with the new growth like this!
If its not the dreaded 'terminal spike', i can go back to looking forward to finding out what it is
