Bob; I think you are correct !! Took me awhile, but I new I had seen this pattern before. This is what I came up with, but it may not be exact, as there are over a thousand different classes of tree ferns. Judgeing by the frons, the grouth pattern of the branches on the trunk, and the cut end of the tree, I also would guess it to be a Tree Fern. Order-Cyatheales. Genera-Dicksonia or Cibotium. Cyatheales is a Tayonmic division of the fern class Polypodiopsida. As for the trunk, tree ferns do not grow woody tissue in their trunk as they grow. The trunk is supported by a fibrous mass of roots that expands as the tree grows to as much as 60 meters. ( How big is that greenhouse ? ) As for the pattern in the center, almost all ferns grow in damp areas, and my guess would be that at different points in time the water ph changed causing the mineral stains and patterns. The bottom of the tree is going to be like a thousand straws bundeled together. It would make a beautiful bowl if you filled all the cells. Peace !! Jim S

Jim, The Nursery tag said it would grow 1m x 1m, the trunk is now 8ft to the start of the branches and is approx, 10in in diameter all the way up. Our greenhouse is 10ft tall and the fern branches are pushing up the shade cloth. I have two options, cut a hole in the roof or take the fern out. LOML doesn't like either option, but something has to give. Trouble is I don't think the trunk is going to get any thicker.
