Hi dear forum members.
This method would be good for many species, but I am focusing now on jaboticabas, could you help us? There are many forum members that doesnt know what kind of jaboticaba are they growing, but if we could compare leaf venation, size, shape and other details, we should identify them properly!
* How can you help? (and we maybe can help you!)
Could you take some photos of the leaves? If you could take good near photos of leaves we can identify it properly.
It would be cool to have photos of your named m. cauliflora paulista, m. jaboticaba sabará, m. coronata, other species, and photos of unidentified jaboticabas (and or eugenias too!).
Any photo of the leaves would be fine, but it would be better if you can take photos like these:
I did that just with my cell phone using android, but you can do it with a normal camera or an iphone too:
How-to:
1) take a leaf of your plant and point it directly to the sun to show their veins
2) the camera should be in "flower" or "macro" mode to focus a near object! (in android, go to Auto --> PRO, Settings, Manual Focus, select the Flower icon)
3) focus your camera or cell phone to the leaf: the leaf should be between the sun and the camera
4) be sure to focus right! take a shot (as much shots as you think till it focus right)
5) upload it here!
your photo should look a bit like this:
There you can also see the sun behind, I let it there just for explaining purposes
A good photo should look like this (although the tip is not visible, it should ideally be seen):
Here you can get some clues of myrtaceae leaf taxonomy (spanish doc):

We can work together and find what we really have!
