 195. R.B. 36:245 (as I.japonica). G.F. 1:259 (adap- 

 ted in Fig. 1975). On account of the presence of 

 a prominent ridge, formed by one or more veins along 

 the middle of the Ivs. of 7. Kaempferi, this 

 species is sometimes considered as distinct "*"*-'*<*, 

 from I. Isevigata. If the species are distinct, 

 the numerous cult, forms of Japanese irises 

 are probably all derived from 7. Kaempferi since, at least 

 so far as available material from forms cult, in the 

 U. S. shows, all have the prominent midrib on the Ivs.

 creeping: sheaths not splitting into fibers: Ivs. linear,
