ID: Veronica ?

Some tiny little flowers, I tried to find the name, some kind of Veronica perhaps but the Visible and UV pattern seems a little bit different to any I found here or on Wikipedia (German version).

 

Taken with modified Panasonic G2 (UV..IR), UV-Nikkor 105mm, at f11 with Baader- U, UV with flash modified Vivitar 285 (got a quartz window).

 

Place: On a wayside Bonn/Drachenfels 9.6.2013

 

PS: picture quality and colors are a bit lousy (edited on a laptop wilth Silky Pix)

Looks like it might be a Veronica persica. A specific foto of the leaf usually helps with Veronica identification.

The example I have posted on the website looks the same in Visible light, but the upper petal in UV is a little darker than yours.

Here's the link: http://www.ultraviol...sian-speedwell/

 

An old study I made of V. persica has a flower with the UV-brighter upper petal - which is to the right in this foto. "-)

Found another one with the brighter upper petal.

Well, that is if we can decide which petal is really the "upper".

Here I seem to have posed the Veronica flower upside down. :)

IIRC, the narrowest petal is considered the "bottom" petal when looking at the way this zygomorphic flower actually grows in the sun.

 

I'm beginning to think my posted V. persica which I linked to above is an anomaly in UV with its darker upper petal.

Hello Andrea,I had considered Veronica Persica, but was not shure, because of the different appearance of the upper petals, which were much brighter with the little flower I found. But the last picture of yours indicates at least also a little bit brighter appearance of the upper one (posed at the lower side). Next time I will try to get more from the leafes as well (though what I can see and compare looks rather similar). What had puzzled me as well was the "change of the bright" zone from the visual picture (lower petal) to the UV-Picture (upper petal).

It is not uncommon to see a white or light Visible area become UV-dark (absorbing)

and a darker Visible area become UV-bright (reflective) -- even within the same flower.

Many combinations and variations are possible.

 

I think these little Veronicas we have found are very pleasing for the way they "flip"

the Vis light/dark to UV dark/light on the upper & lower petals. :)

 

There can be variations in colouration within a species.

As we build the website here, I hope that we will eventually several examples of each species

so that we can illustrate some of the colour or pattern variations whether in Visible or in UV light.
