What happens with too many VLANs?

In the production network, we have 2950s that support up to 250 VLANs.
But they only support 64 separate VLANs running individual instance of
Spanning Tree....... So my question is what happens when you add that
65th VLAN? I partially know the answer is that you will see in the
config where it says "no spanning-tree vlan <blah>" where <blah> is the
# of the VLAN (or VLANs) over 64. But how do the rest of the switches
handle this? Do the switches toward the root treat this switch as an
end-device from a STP perspective?!?!?
 
Any input is appreciated........ just wondering how to plan and what to
do to make sure nothing breaks now that we've passed 64 (actually 68)
VLANs on the network........
 
Thanks!
