Solanopteris brunei - from Colombia - Info:


Recommended Posts

There are claims on the WWW that the domatia within tubers of Microgramma are created by ants eating tuber contents, I suspect this is incorrect except that resident ants may enlarge upon plant produced domatia. Has anyone cultivating tuberous microgrammas confirmed this?

Here is an interesting link with images of Microgramma brunei with tuber structure details.

There are some macro images of Microgramma bismarckii I have photographed and posted. This was the most fitting place to post the images.

I will follow up with more images of a tuber I have preserved that I plan to section; to get more details on the natural, versus ant created boundaries of the tuber chamber formation.

Here are some Microgramma bismarckii tuber images:

The tuber is split vertically in line with the rhizome attachment and the entrance canal. It has been in a preservation solution. This tuber is from the same fern in the link above.
