Wood from Russia

Wood from Russia - Need Ident help

Okay so I know this doesn't really belong in stabilization and casting but I started a thread here earlier to get help so I figured I'd leave it here.

Below are the woods my wife and I picked up in Russia. All but the 4th picture are supposed to be Russian woods. I think I might know what most of them are but I'm not sure. I'm excited about working with these woods because they look pretty interesting.

1 - I'm not sure what type this is but it is one of the ones that would need to be stabilized.
2 - This I believe is either a Russian Nut wood or Olive wood, doesn't need stabilized.
3 - See #2, this one will need a little CA glue for one of the blanks I make but I can get that done easy.
4 - This is the non-Russian wood. I believe it's Bubinga.
5 - This is a type of Birch. It's either spalted or burl I don't remember the word he used in Russian and since I can't identify wood yet I'm not sure. This three will need to be stabilized and one will be sent to my dad as a father's day present.

Thanks for the help!

Pics 1 and 5 both look like Masur Birch. Although pic one is kinda dark for it.

If number 2 and 3 smell like Olive Oil, then they may be Olive Wood from Southern Russia, otherwise they are more likely Russian-Olive which has a fruit that looks similar to an olive, but isn't. That hyphen makes a world of difference.

Well pic 2 does smell faintly of olives but pic 3 is supposed to be Russian Walnut (or at least a walnut tree that grows in Russia.

The first one is not the same Birch as the other 3, at least that's what the guy said.

I agree, pic 5 looks like Masur Birch. It grows mainly, if not exclusively in the Scandanavian region of Europe. I believe it is sometimes referred to as Arctic Birch. The interesting figure occurs when the tree heals itself after being infested by a boring beetle (that would be a beetle that digs in..... not one that has nothing interesting to say).

So any guesses about the first one. I might be remembering incorrectly but the guy said it was something different than the Masur Birch (I'll have to look up that in Russian and see if it jogs my memory). Plus I'm back at work today so I'll ask one of our Russian instructors to name off a few Russian woods since they seem to know every type of wood, mushroom, fruit, bird, and anything else you can find in the woods.
