 the case of <nnerkana.

Variegation marginal, yellowish green. 



Recognized since 1865, when it was found in French and 

 Belgian gardens under the name A. laetcolrens, which Koch had 

 found applied in 1862 to a median variegation of A. americana, 

 from which this is very distinct in specific characters as well as 

 in its variegation marks. It is one of the least decorative forms, 

 and, apparently never common, appears today to be one of the 

 rarest.

') Dr. Franceschi infornis me that this name has been in use in European gar 

 dens for the plant for over a Century, so that the date of introduction is doubtless far 

 earlier than that here given ; but its carlicr histoiy seems not to have been recorded.
