Table I. — Showing the condition and number of each of 15 distinct 

 varieties found in the examination of 2794 specimens. The fractional 

 parts refer to those cases in which one or more of the sepals is notched

 above is, that those botanists are in the right who, with De 

 Candolle, consider Tormentilla officinalis as a species of the 

 genus Potentilla under the name of Potentilla Tormentilla.
