J^. turbinella belongs probably to the J^. chrysolepis group, 

 and evidently close to J?. vacciniifoUa Kellogg, but lacks the 

 white bloom usually found on the lower sin-face of the leaves 

 of the latter ; the teeth are more distant and more decidedly 

 spinulose tipped, and the cup is more turbinate.
