The least decorative form when most typical, but insensibly 

 passing into the median type and correspondingly brighter, the 

 leaves of a given plant often presenting great differences.

Variegation marginal, white or creamy to rather bright yellow. 



The general failure to distinguish A. picta 

 from americana ma)-(jinata makes it practically im- 

 possible to properly coUocate undescriptive refe- 

 rences for the past fifty years, and the garden 

 synonymy of the whitermargined forms, here and 

 under americana, is doubtiess confused. Except 

 for rare regressions that B e r g e r has observed on 

 the Riviera, it is questionable if the normal type 

 of the species represented by this variegated 

 form has been seen, and the latter, which is 

 commonly grown on the Mexican tableland and 

 now freqiient in gardens elsevvhere, may be of 

 even greater antiquity than the comparable form 

 A. picta. of americana : Were its normal type named, A. picta.
