R. podophylla, the only known species of the genus, 
inhabits open subalpine mossy woods in Japan, at Yesso, 
Hakodadi, and on Fudsi-Yama, flowering in June. It was 
introduced into the Imperial Botanical Garden of St. 
Petersburg by Dr. Maximovicz, where it flowered in 1871. 
Our specimen is from a plant flowered by Messrs. Veitch in 
June of last year, which was raised from seed sent by their 
most successful collector, Mr. Maries.
