Next time, leave the keikei attached to the cane.... With it's nice roots a growth would have popped off the side of it in no time. It is rather small, but hey I've had stuff sprout that I'd thrown in a pile to get ride of recently. I took some pics recently of some things I NEVER expected to do anything but die. Amazingly, these two tiny p-bulbs off a den had completely yellowed and looked dead but this tiny sprout grew off them after I'd thrown them into the Epidendrum basket to let them rot. lol I sure was suprised when I found the sprout coming off it! So, give it a try....what is the worst that can happen? Its already headed out anyways...
Good Luck!
