Yellow Archangel (Lamium galeobdolon)

[Jim Lloyd]

Photographed a few wild flowers today (after completing 10K running race - so I think I was a little tired!)

 

May show a few other examples latter - or re-shoot. This one caught my eye. Once again I don't know what it is called despite trying to search in a book I have (A field Guide to Wild Flowers of Britain and Europe - Thomas Schauer - Collns, London, 1982). It grows pretty commonly around here on verges and field edges. The closest I think was Yellow Rattle - Rhinanthus - maybe ? Looks a bit nettle like - or possibly some form of mint or other herb. This really shows up my ignorance! Anyway I thought it had some interesting UV features - particularly the blue tube / rib like structure at the back of the flower (ignorance again!) [Edited title to correct flower after Andrea's input ...]

No, that's a Lamium of some kind. I think we have a photo of this by Bjørn somewhere.

Found it: http://www.ultraviol...llow-archangel/

 

And another one from Nico:

Jim, Personally, that is one of the more interesting UV pattern shots I have seen for a long time.

[Jim Lloyd]

Thanks Steve! It’s interesting when we see differences between the uv and visible image. I don’t know what the significance is in botanical / scientific terms, but it’s a fascinating reminder of what is hidden from our normal vision

 

Thanks Andrea - yes known as Yellow Archangel and a form of dead nettle from what I have quickly seen on internet

 

Interesting what I found with a bit of searching - in some parts of the world (eg Washington USA) classed as a “ noxious weed “ with control recommended to avoid invasive spread. In U.K. woodland trust actively manages woodland to encourage it. Funny our relationship to nature at times ...

I found a variant with variegated leaves and less prominent markings on lower flower lip this morning while walking the dog. Stuck at work now though ...

As they always say about weeds - just a lovely flower growing in the wrong place.

 

Some of the Archangel you are finding could have escaped from a garden somewhere. Is the plant grown around there as a garden ornamental?

 

So make a comparison shot of the the two pattern differences in visible and UV. Might be interesting!

[Jim Lloyd]

Not sure there is a difference. A few shots taken this evening. [i wonder if the title of this thread should be changed to the correct name now?]

 

Same settings as above, but with a new lens (essentially I think it's the same as the Photax, only got it today and haven't tested) - Optomax 35mm f/3.5 preset - M42 not sure if there is an underlying T mount. Set at f/11. R720 filter for the IR shot.

It's always fun to discover a flower having two false colors.

And look at that fringe on the upper petal - cool !

Ahh - I couldn't find where to edit the title before, but done so now. I think the full editor isn't available on mobile devices
