The /ris here figured was discovered by Professor J. K. 
Urumov at Eski Dzumaja in Bulgaria in 1901. In his 
monograph it was referred by Mr. W. R. Dykes to J. Sin- 
tenisti, Janka, but, on raising plants from seeds obtained 
from Messrs. Vilmorin, Mr. Dykes recognised it as distinct. 
This decision has been confirmed by a plant received by 
the Hon. N. C. Rothschild from the original locality in 
Bulgaria. The difficulty experienced has been due to 
the original description. Dr. Velenovsky has described 
the plant as having green leaves and greenish spathes, but 
these organs, as Mr. Dykes points out, are glaucous, this 
colour being enhanced by the fairly large white asperities 
on the nerves. The dimensions here given have been 
Apri, 1915.
