Tillandsia psittacina. Hooker in Bot. Mag. t. 2841. 
Although the limits of the genera of the Bromeliaceous 
order are much better defined than they were a few years 
ago, there are no doubt some distinct groups still concealed 
among the little known species crowded together under the 
name of Tillandsia. The present instance we conceive to be 
one of them. 
Although referred to Tillandsia this has neither a supe- 
rior ovary, nor the scaleless petals that are essential to that 
genus. On the contrary, it evidently belongs to Endlicher’s 
second section of the order, at present consisting of Pitcairnia 
and Brocchinia only. From the latter it differs in its revolute 
scaled petals, and distinct filaments ; from the latter in its 
distinct sepals, and regular revolute petals. From both its 
large channelled coloured bracts distinguish it at first sight. 
Along with it will have to be placed the Tillandsia heli- 
* We have takeu the opportunity of thus commemorating the merits of 
Dr. W. de Vriese, Professor of Botany at Amsterdam, an excellent Botanist 
and Physiologist.
