<![CDATA[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. ]]>
