The petal appendages in Pseudanatias consist of a 
pair of thick fleshy ridges which are produced along their 
inner edges so that they overlap the filament of the epi- 
petalous stamen. They are thus wholly unlike the del¬ 
icate funnel-shaped appendages of Ananas. 
As already indicated by Castellanos, Bertoni’s use 
of Ananas microcephalus corresponds to Pseudananas. 
The identity of true A .microcephalus is wholly uncertain. 
Baker and Collins could find no material to support the 
varieties proposed by Bertoni either in his collection or 
in localities from which the varieties had been described. 
All their material indicates that Pseudananas macrodontes 
is a very uniform species.

The description of Bromelia Sagenaria shows certain 
similarities with Ananas bracteatus , but it shows also 
differences that it is practically impossible to explain 
away. For instance the floral bracts are given as about 
twice as large as they are ever known to occur in Ananas
