About the Author
Michael Sundue
My field work is centered in Colombia, and Papua New Guinea. I am based at the Royal Botanic Garden Edinburgh (E). If you have any ferns that you want identified, please send them to me!
Wow! What a huge plant! Interesting to see the cross-section of the petiole, with its ground tissue black and vascular tissue white. I saw this for the first time in Elaphoglossum last year, in a species endemic to Ecuador. I wonder if it is a useful character state (or perhaps the cells were just dead and rotten…). We need more petiolar cross-sections of Elaphs!
I have seen that in some Elaphoglossum as well. In this case, the black sclerotic ground tissue is diagnostic for the species.
Very interesting… Do you remember which species of Elaphoglossum it was?
I observed this only once in Elaphoglossum clathratum, a species that belongs to E. sect. Polytrichia. I wonder if the one you saw also belongs to this clade.
Sorry, no idea!
