The subject of our illustration, Rhododendron sublanceo- 
latum, is an Azalea which is cultivated rather widely in 
Japan as the ‘Chinese Azalea.’ It is undoubtedly very 
nearly allied to R. indicum, Sweet, and observers so 
competent as Dr. Buerger and Mr. Makino have even 
suggested that our plant may be considered a variety of 
that Chinese species. But &. sublanceolatum differs so 
markedly from R. indicum, not only in the size of the 
flowers but in the form of the calyx, that this suggestion 
appears to be as unnecessary from the systematic as It Is 
inconvenient from the cultural standpoint, and there is no 
doubt that Mr. Craib is justified in treating the two as 
distinct. It now appears, moreover, that £. sublanceolatum.
