DESCRIPTION OF PHOTOGRAPHS OF PLATE XXXV 
All sections are transverse, in the region just below the departure of the traces. 
Photo, i. Betula, trilacunar type. X 20. 
Photo. 2. Cornus, trilacunar type. X 12. 
Photo. 3. Lindera, unilacunar type. Although the gap is single, there a!re 
three bundles in the trace, indicating that the unilacunar condition in this instance 
has probably arisen by the approximation of three originally distant strands. X 25. 
Photo. 4. Eucalyptus, umlacunair type^ In this case the trace is single. X 20.
