Apart from colour, there is very little to separate this 
plant from Iris persica, Linn, (Bot. Mag. t. 1), which, 
however, has the inner perianth-segments toothed. The 
peculiar colour of the flowers of the present plant is 
difficult of definition, and has been compared with that of 
the soil on which the plant grows. It is produced by a 
silvery-grey ground being covered with a large number 
of fine, closely-placed, reddish lines. This species was 
introduced from Asia Minor by Mr. W. Siehe about 1901, 
and distributed as J. Haussknechtti, a name which had 
been previously given by Bornmiiller to a plant belonging 
to the section Apogon. At Kew this species commences 
flowering in a south border in February, and produces a 
succession of flowers for several weeks. 
Of the various species, besides I. persica, figured in the 
present work belonging to the section Juno (characterized 
by the small spreading inner perianth-segments), the 
present approaches nearest to J. rosenbachiana, Regel 
(t. 7135), which differs in having broader leaves and 
larger, acute crests. The latter is found in Turkestan, at 
an elevation of from 6,000 to 9,000 feet. This section 
occurs chiefly in Asia Minor and Western Asia, but one 
species, I. Aitchisoni, Boiss., is found in Afghanistan and 
Feprvuary Ist, 1906.
