Iris Leichtlini is very closely allied to I. Eulefeldi, 

 Kegel (tab. 6902), a species referred to by Baker as a 

 variety of I. scaiHosaj Willd. ('*Handb. of Iridese," p. 32), 

 which differs notably in the plane margins of the perianth- 

 segments and bipartite crests of the style-arms. J. Korol- 

 kovi, Kegel, (tab. nostr. 7025), is another nearly allied 

 plant, but it differs from I. Leichtlini by the same 

 characters of perianth-segments and style-arms as does 

 /. Eulefeldi. All three are natives of Russian Turkestan, 

 and are variable in colour, but I. Leichtlini is the most 

 beautifully variegated of the three, and is the only one of 

 them (as far as yet figured) with brown and violet periauth- 

 segments. 



Central Asia is probably the head-quarters of the genus 

 L-is, about thirty species are enumerated by Baker as 

 inhabiting this region, whence, and especially from Tibet 

 and the regions bordering China, many novelties may 

 be expected; about forty species are European, sixteen 

 Himalayan.
