- The plant from which the drawing now given has been 
prepared was obtained for the Kew collection by purchase 
from the Yokohama Nursery Company in February, 1908 ; 
afew days after its arrival a flowering example of the 
same species was presented to the herbarium at Kew by 
Mr. W. E. Ledger, who had grown it in his garden at 
Wimbledon. The species, which is described in the Yoko- 
hama catalogue as “a lovely tiny Iris, 4 or 5 inches high, 
with yellow flowers,” is only known ina cultivated state. It 
is generally assumed to be the plant described by Franchet 
January, 1910.
