I think it is another name for Lemonwood. I read the article, and yes I did see they also stated Lemonwood. The time period the most popular woods were osage, yew, and lemonwood. I remember (vaguely) the word Boam I think yrs ago the question was on stickbow, I could be mistaken. Ask Badger he may know, he spent time on stickbow.
