Westerleigh Aquarium, Plant ID and Info

I received an advertisement from Westerleigh Aquarium and I am assuming 
that they obtained my name and address from the AGA member list.
They had a few plants I'm interested in as well as quite a few of the 
more common species. 
The water orchid I am assuming is Spiranthes (listed in the Dennerle 
catalog as well as other texts). The nitilia I am guessing is nitella?

Other species of interest are fontinalis and Utricularia minor. I have 
raising local (Minnesota) forms of the fontinalis and Utricularia without 
much luck. 
Any recommendations on cultural conditions on any of the four species 
from someone who has been successful?
