252 BALFOUR—-RHODODENDRON : 
seems to want the under stratum of rosulate hairs, the flowers 
are few and much smaller in all parts—and altogether it looks so 
different that I did not bring the later arriving large-leaved and 
flowered specimens which were described as Rh. aemulorum into 
correlation with it. If they be the same then the name aemu- 
lorum gives way to mallotum. Rather than make this name- 
change just now on the evidence I leave the two names giving the 
caveat I enter above.
