 genus. When in fruit the postical $ and $ would readily identify 

 it, but $ has only been sparingly found b}'- Dr. Carrington in 

 Ireland, and no perianths have yet been discovered on British 

 specimens. When barren, distinguished from Plagiocliila punctata 

 Tayl., which it resembles somewhat in size and habit, by its dark 

 lurid green colour, leaves usually unispinose, antical margin 

 incurved, and the large hexagonal cells. 



The description is taken from Dr. Spruce's valuable notes in 

 "Journ. of Bot." (1876).
