<DIV>I understand taxol is derived from the Pacific Yew. Is there any
evidence that the ornamental yew so prevelant here in suburban yards on the
East Coast could be useful for taxol or tamoxifen production? People here
prune yews usually into ugly box shapes at least once yearly and dispose of
the branches in landfills.</DIV>
