I haven't been involved with the beauty snakes for quite a few years, but to the best of my knowledge there has been no morphs of the taiwan beauty specifically.
The taiwans are a subspecies of a larger group though and morphs of some of the other subspecies have been found such as albino and calico, and a couple of others.
When I was keeping them they were in the genus Elaphe. The genus has been changed I do believe, but I still refer to them by that name out of habit.
Taiwans are
Elaphe taeniurus friesi. I do not remember exactly, but I believe the albinos were either the Chinese Beauty snakes (
E.t.taeniurus), or the Mocquard's Beauty Snake (
E.t.mocquardi)
I have no experience at all with the Baron's Racer.
Here's a pic of one of my clutches of Taiwans. She was about 7 1/2 feet here.
