ID help (Robinia species?)

Question

There are a couple of Robinia's nearby my house, and this is the first time that I've been able to see them flower.

There seems to be three kinds: the typical Robinia pseudoacacia with white pendulous flowers and bright green-yellow leaves, a similar version of the pseudoacacia with smaller leaves and no flowers, and another that has smaller green-brown leaves, with bright red new growth. However, none of them seem to have thorns (except one tree that is very young, maybe 2 years old).

The third is the one that piqued my interest, as I haven't managed to match it's flowers to any Robinia species. Here is a photo of the flowers:

The flowers are quite small. At first I thought that possibly the flowers had just started to grow, however I never ended up seeing any flowers larger than the above photo.

Robinia have pea flowers. That aint a pea flower! What makes you think its a Robinia?

There is a hardy, thorny Robinia species that is used for grafting stock for other less hardy, more friendly Robinia species. A MopTop is a grafted Robinia standard, pretty common. The stock Robinia species tends have an extensive and invasive root system that can extend into the yard of your neighbours neighbors neighbour! Tend to sucker like a mother fucker as well. Fast growing thorny bastards of things, and in thick stands. Think bamboo with thorns.

That shit should be declared a weed!

If you have a young thorny Robinia nearby, one of those other Robinias are probably grafted.

KIll IT!

Robinia was my best guesstimation. Looking more closely today, there are a few differences so I may have been wrong, however they are all very similar, and the root systems of the two smaller-leafed trees seem to be quite invasive..

I am relatively sure that the larger leafed tree is a psuedoacacia as I saw it flower.

I managed to find a seed pod on one of the red-leafed trees today (155mm long):
