The handsome Rhododendron which forms the subject of 
our figure has been known for some time in collections 
under the name &. Metternichii, Sieb. & Zuce. It is not, 
however, the same as the plant so named by Siebold and 
Zuccarini, which differs from that here depicted in having 
a corolla with seven lobes, in having fourteen stamens and 
in having a seven-celled ovary. ‘The form in question is, 
however, the one that was originally described by Blume 
under the name /Hymenanthes japonica; to the use of this 
earlier specific name Schneider has recently reverted, though 
it is remarkable that in doing so he has not alluded to the 
existence of the variety now figured. Like the typical 
plant our variety is wild in the mountains of Central 
Japan, and both are frequently met with in gardens in 
November, 1911.
