The common salicylic drug we all know is aspirin, but it's not derived from
willows.  It gets it name from the German name, spirsäure,  of a synthesized
form of salycilic acid.  The “spir” in spirsäure  is derived from the name of
the meadowsweet plant, Spiraea ulmaria., a rosaceous plant.  

Here's how the wikipedia puts it "The name Aspirin was derived from the name of
the chemical ASA—Acetylspirsäure in German. Spirsäure (salicylic acid) was named
for the meadowsweet plant, Spirea ulmaria, from which it could be derived."
