*Neutral on name - "shrub rhus" gets 131,000 "shrub sumac" gets 86,000, which suggests that when Persian cookery is taken out the proposed move has more going for it.    

 ==Fork discussion== 
 Always difficult to know how to handle a Fork discussion inside a RM. See Talk:Cơm tấm for a similarish example between a bio product and cuisine. 
 *Support fork - per Sminthopsis84 and JonRichfield - I also think it would be desirable to have two pages, the genus page Rhus (or Sumac), and a page about the spice, called Sumac or my preference Sumac (spice), Sumac should still direct to the shrub/genus and that be hatnoted to the spice. Wikilegalistically speaking "(spice)" parenthetical disamb isn't needed per TWODABS, but one can see lack of it causing all kinds of mischief and trouble in the top R/H search box if it isn't there. A fork would also allow better categorization and encourage sourcing up the spice section with Sefardi and Iranian cuisine refs.
