Jacksparrow, following your throwing of beech and willow into the pot, I spent a good deal of last night when I should have been watching Notts beat Essex checking out both suggestions.
Beech I can see but willow I can't get close to.
I agree - have to wait for more clues from the plant itself next Spring, I s'pose. Interesting though .......
P.S.: I don't consider your knowledge of t's and l's to be very limited at all at all.
