132 WILSON EXPEDITION TO CHINA 



Wilson's specimen differs from the type in the nearly subulate bracts and the 

 larger leaves and possibly does not belong here, but without flowers it is difficult 

 to place.

Most nearly related to L. tangutica Maxim., which differs chiefly in the smaller 

 and narrower acute leaves nearly glabrous on the imder surface or only sparingly 

 pubescent on the veins, in petioles and veins not being yellow, in the subulate bracts 

 not exceeding the ovaries, in the corolla glabrous on the outside, and in the style 

 being glabrous or only furnished with a few hairs near the base.
