Black or Hybrid ?

[David Humphries]

At a request from a local artist, I have been on the hunt for any Populus nigra ( Black poplar.)

 

On a tip off from a colleague, I had a look at a couple of local trees today.

Seeing them on the side of the highway makes me siddle away from them being nigra's, so my guess is that these are Poplus x canadensis (Hybrid Black poplars)

 

Thought I had a shot of the tree in situe, but must of deleted it.

Tree is appox 18-20m, but having been pollarded (sic)

and looks to be on a 5-7 year cycle.

 

1st on the branch

2nd top side

3rd underside.

Btw, the leafstalk is very flat.

 

Have tried the usual suspects, Mitchell, Dorling Kindersley et al., and I'm none the wiser.

Any thoughts fellas ?

 

Also, anyone know of any Black Pops in London.

I have the BSBI handbook of willows and poplars in front of me, and the leaf looks more like the hybrid to me.

Both nigra and x canadensis have the flat petioles, although nigra's are slightly shorter, 3-7 cm as opposed to 4-10 cm. nigra has no glands or swellings at the junction of petiole and lamina, x canadensis usually has one or two glands.

If you want the relevant pages I could scan and send you the info....

Anything nearer North London Dave?

 

Vespa's in the body shop at the moment due to ending up on the deck twice within 24hrs last week.

 

So without wheels, something more local would be good.

Almost certainly Hybrid, Native Black Poplar have a much longer leaf tip tapering off to a fine point.

The tree is probably matchsticks now.
