D9 SRis had the 16", but 15" versions were found on the post 2002 Rapiers.

Ah, yes - forgot about the later S models which have them. Only other 16" 406 wheels were the Hoggar (with 7 flat smooth spokes) which were on the later Executive, SE & coupe models & the 16" Starfish wheels which are on the earlier coupes.

It would seem that they different names for different markets but after a quick check, I note that Servicbox lists them as Boreal so I am feeling at least partly vindicated!
