I am currently working on my pre-dissertation research and am looking for any insightful information regarding the "debate of the cambium" that occurred between William Crawford Williamson and Adolphe Theodore Brongniart in the mid- nineteenth century. Williamson argued that Brongniart was wrong in suggesting that if the stem of a fossil plant contained a secondary growth of wood, product of a cambium layer, it could not belong to the cryptogamic division. Whose views are accepted today with respect to this debate? Any information would be useful.
