Is this a Spike a Keiki or Other, on my hardcane Den?

[RosieC]

Ok, so my Dendrobium (phalaenopsis type) is growing something and I don't know what it is.

I've never re-bloomed a Den, so it could be a spike for all I know, but it doesn't look like I would expect for that.

I bought this Den just over a year ago in flower, then at Christmas I noticed the start of a new cane (shown in the first pic).



This has grown all year and is now about twice the height of the original cane which has been pushed to a sideways angle as this new one grew.

It had stopped growing and seemed to have terminated.

About a month ago I put it outside in the sun-shine for the afternoon (being careful that it was not burning). I had heard from Hedge that her's had done well and spiked with outside sunshine here in the UK and while I thought it was too late to get flowers I decided to give it more light when I could.

A week or so later I noticed the start of a tiny new growth. Since then it has gone outside on a couple of sunny days including this afternoon.

This growth is noticably extending...

So any idea what it is?
