Hi all,

After searching around for some time, the only explanation I could find as to why crab apples are called 'crab' apples, is on account of their small size. This seems odd to me, as I've never used the term 'crab' to convey any kind of intention related to smallness. If anything I would have guessed the 'crab' in their name would indicate some kind of ill-mannered temperament - but then, that doesn't make much sense either... for a plant.

I was surprised to find there are many species of Malus, so I won't even try to pinpoint which this may be:

The nice iridescence in this UV view is much more evident in the full-res image:

The petals have such a fleshy red fluorescence in this UVIVF view, different from the chlorophyll fluorescence in the leaves:

If you look closely in this IR view you can notice two anthers glowing blue right through one of the petals :) (image upper middle):

This UVIIF view shows nice false colors, but it doesn't quite have the 'glow' I like:

Now this CyIIF view has the glow I like - enough to be seen right through some of the petals!

Very nice!
You images with a leaf, remind me I should include a leaf with mine as well. The leaf in images 3 and 5 are very nice. But I agree that I like the glow better in 6 than in 5 for the flowers.

My understanding is the name reflects the very tart taste of their small fruits.

I see. I suppose a sufficient dose of malic acid would make me recoil to a crabby disposition as well. (I feel a food adventure coming on!...)

If you eat one (and I have), it makes your mouth pucker up horribly. You can try it once but I do not think you will repeat this experiment.
