the book "Comfrey Report: The Story of the World's Fastest Protein Builder and
Herbal Healer" by Lawrence D. Hills written in 1975:
"There are two
commercial strains-- the Webster and the Stephenson. The Webster Strain: This
is the most popular commercial strain, started by the late R. O. Webster to have
been imported by his father from St. Petersburg, Russia, in 1900. Bocking No.
4- This is the dominant in the strain, about 50% to 60%. The flower color
is Bishops Violet 34/3 when fully open. It has strong stems and small wings. The
leaves are broad and round tipped; their proportion is 5 to 10, but they have
no incurling: therefore they appear far wider than a No. 1, for example. The edges
are unserrated, and the veins are prominent, with bristles thickest on the underside
so that the upper leaf surface appears smooth. At leafy stage these leaves are
very large, recovering rapidly from cutting. The stems, as in all variations under
trial, are solid."
