Or Rothamsted's GENKEY (a Fortran version dating from the 1960s that
needed something like 32K, if I recall). *As I said, it wouldn't
take me long to write one - probably less time than searching for
the code of one.
The problem is getting the data - and, worse, in persuading 'data
owners' that such a thing is worth doing.
I agree with you.
What? *That Rothamsted is the weed? *;-))

I'll try again . . .
I am still trying to identify this plant.
I have added three photos to the link (I now have much more respect
for plant photographers - it is not easy !)
One shows the "opposite" leaf arrangement and how new shoots grow out
of the "armpits" -
rather like tomatos.
Another shows the tiny purple/blue flowers about to come out.
At this stage the bottom part of the main stem has (often?) turned
from green to red.
The third one is, I hope, a better overview.
The main stem, as well as becoming red for the bottom approx. 40%, is
also not
really round; it appears to have vertically-running ridges.
Total height of most mature specimen is about 60 cms.

Definitely a willowherb. Not sure which one, though. The leaves look
like Epilobium angustifolium, but they develop quite tall spikes of
flowers.
It's not one of the larger flowered ones (angustifolium and hirsutum).
I'd guess that it's Epilobium montanum (broad-leaved willow-herb), as
that's the commonest of the small-flowered species, but the books don't
specifically mention is having vertically running ridges on the stem.
The key characters for E. montanum are a four-lobed stigma, all stem
leaves in pairs, and sessile (or at most shortly petiolate at the base).
E. lanceolatum (narrow-leaved willow-herb) also has a four-lobed stigma,
but the upper leaves are alternate (borne singly), and the leaves are
petiolate (stalked) and cuneate at the base. If it has a club-shaped
stigma there's several possibilities. One feature worth checking is the
number of vertically running ridges on the stem.
