C: a part of a flower
D: a secret

I haven't the faintest idea about all 4 photographs!

Is it an aquatic plant?

WOW-photos!

I would like to know with what you are taking these out-of-situ photos? Do you have a stereomicroscope with an attached camera? I was ordering one for myself, but I do not know the results so I kept back.

il-Pine: really no idea? Pic A is a real wild one, indigenous, very common-
B is frequent in the wild but not really indigenous (the taste is absolutely delicious)!
C is an ornamental, sometimes in the wild, too
D is a secret, but I am sure only for another day-
MWP: yes, it is (in the case you mean D)!

-still 3 days time for you to search-

regards to picus

A: JUNCACEAE, CYPERACEAE, POACEAE ??

B: ?! pic not very clear ?? Is the fruit commercial? (Eg: Vitis!?)

C: Aizoaceae? (too good to be yes!)

D: Wolffia arrhiza !

Let's try

A)Graminaceae
B) Ficus carica
C) Carpobrotus?
D) Chlorella! (I am remembering my O-Level examination!)

Maybe I hit one!

Pine, actually Chlorella is a better guess. Haslam don't mention it, so I taught of Wollfia at first. (it also says budding!) . If it was Wolffia jackpot would not say "D is a secret". We see his response

ok- the secret with D is over- yes, it is Wolffia (yes MWP, this pic was done with a stereomicroscope with an attached camera.
A & C is pretty wrong and therefore, extremely cold, by both of you-
B: Pine is somewhat warm!

Bwah! I should have more confidence in my botanical conclusion than to my detective ones!

D is out then!

Is the direction of Chenopodiaceae for A a bit warmer?
Is C really hanging over head, might be like a very early Eucalyptus?
And what`s about the Ficus for C?
My first idea was, small bulbillas with a rest of flowers. But I prefer the idea of Mulberry-Flowers.

Yes true A might be a Salsola

jackpot · Post by **jackpot** » Tue Sep 05, 2006 6:41 pm

applause-
yes, A is Salsola soda
B is in fact Morus albus-
and C is Eucalyptus leucoxylon
....very very good!

applause to you. very nice photographs

What are the brown linings in pic D? And it is stereomicroscopy with top illumination or darkfield or bottom illumination?? My pics at work are different (more texture detailed but not as x-rayed through as yours).

Do Wolffia has down growing rootlets in water?

jackpot · Post by **jackpot** » Wed Sep 06, 2006 6:56 pm

damaged chloroplasts (first brown then getting black)-
they never have roots!
Foto was a combination of light microscopy and (we call it): Interferenzphasenkontrastmikroskopie (don`t try to say it)

Thanks, il-Pine (but Bernd shot pic B)

Thanks very much JackPot -

Yes I can say it

Interference Phase Contrast Microscopy, works with the principle of converting different densites of specimen (refractive indexes) to visual contrast differences (hope my microscopy credit in 1998 still holds!) Much used for living cells without the need of killing by staining or mounting. (some educ for the students!)

This week I started experimenting a bit at work with a stereomicroscope (very nice viewing with background music from the implimented stereo

- not for students!) Maybe tomorrow, I will post something - perhaps a quiz!

Thanks for the info again.
