Highbush cranberry, a Thompson “Chinuk Wawa” word

Annie Zíxtkʷu York said, in “Thompson Ethnobotany” and the “Thompson River Salish Dictionary”:

Highbush Cranberry

kʷúkʷns  ‘highbush cranberry’ is a Chinook Jargon loan into this southern interior BC language.

This is new to me.  Any ideas of its etymology?

There are a number of other words labeled as Chinuk Wawa loans in the TRS dictionary, as I recall, that are as puzzling as this.
