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 onlv. 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 taken the opportunity of thus commemorating the merits of 

 Dr, \V. de Vriese, Professor of Botany at Amsterdam, an excellent Botanist 

 and Physiologist.
