 on rocks in dense compact tufts, or creeping amongst mosses, 

 when it is remarkably flagelliferous. Moderately rare.

Found on the Continent. 



Obs. — Distinguished from PlagiochUa qnnulosa (Dicks.) by its 

 smaller size, more compact habit, darker colour, rounder leaves, 

 which are more transversely inserted, not decurrent, cells slightly 

 smaller, bracts broader proportionately, perianth shorter with 

 longer cilia ; it is also more flagelliferous. I do not rely much 

 upon the punctate character of the leaves, for there is little 

 difference to be observed in the cell structure of P. spinulosa and 

 P. punctata.
