Very interesting reading. I must learn more about lignotubers, but I suppose they have not developed on my plants yet. If I knew you would use the image of my plants, I would have put more effort in the photos. Always fun to have your plants used as bad examples :-)
Gus, do you have an idea of what Euc it can be on my image? We concluded in an earlier discussion that E. gunnii or E. gunnii ssp Archeri are good guesses. What do you think?
