wattap etymology?

[David Robertson]

Ives Goddard has an article "Algonquian Linguistic Change and 
Reconstruction" in the volume edited by Philip Baldi, "Linguistic Change 
and Reconstruction Methodology", published in 1990 by Mouton de Gruyter.

In this article, Goddard mentions a Proto-Algonquian cognate for Yurok & 
Wiyot (NW California, distant relatives of Algonquian), all forms in the 
set meaning 'spruce root' apparently. 

The form in PA is *watapya.  The Yurok is 7wohpeG (G=gamma), the Wiyot is 
to`p.

Is this not the word we know in English as <wattap>, among other spellings, 
in historical sources?  I'd thought it was a NW word, but it looks possible 
that it's from back East, from some Algonquian language.  

I don't have access to a specialized enough dictionary of English here at 
home, so I wonder if someone else can tell about this.
