The beautiful variegation of the leaves in this variety 
is due to a lack of chlorophyll near the margin.

The earliest name for the cultivated pineapple is 
Bromelia Ananas L., but as the International Rules of 
Botanical Nomenclature do not allow exact repetition of 
the generic name by the specific, the next earliest name 
must be used. In this way we have Ananas comosus (L.) 
Merrill based on Bromelia comosa L. Ananas sativus has 
been much in use but is antedated by the claim of A. 
comosus and so must lapse into synonymy. 
No attempt is made here to classify the numerous 
subdivisions of the species, but in line with the policy of 
evaluating Bertoni’s names, two of his so called varieties 
of A. bracteatus are reduced to the synonymy of this
