124 BALFOUR—NEW SPECIES OF RHODODENDRON. 
—the large calyx about 1.5 cm. or more long and the pubescent 
filaments of the stamens. The “Io stamens” of the descrip- 
tion (both Latin and English) is a misprint; 17-20 stamens 
are shown in the drawing and are present in specimens which 
the Director of Kew kindly sent to me. I read no character 
that would deny Sir George Watt’s identification of Rh. Mad- 
dent, var. obtusifolium, with the plant here described as Rh. 
manipurense.
