Hab. — On hedge banks, rocks and stones, rarely on rotting 

 wood. Rare. 1. Hedge banks near Redruth, Cornwall, 1871, 

 The Lizard, Cornwall 1883, W. Curnow. 5. ? 8. Crich, Derby- 

 shire; W. Wilson, 1833. 12. Westmorland, G. Stabler ; on dead 

 trees, Rigmaden Park, Westmorland, Peter Brecsen. 15. Scottish 

 Highlands, Drummond. 



Found on the Continent (Schwartzwasser, Sudetia, Hb. Nees, 

 as Jift/f/, Starkii, var. mimiua). 



Oes. — Differs from C. divaricata (Sm.) in its monoicous 

 inflorescence, leaves often very widely spreading, at the immature 

 flower ends squarrose (hence I suppose Taylor's name), perianth 

 always trigonous (not 4-6-angled), angles acute. 



In the original specimens from Crich the perigonial bracts are 

 dentate, in those from Cornwall and elsewhere they are quite 

 entire.
