Very variable in size, colour and branching. Usually laxly growing in very expanded, 

 yellow-green tufts, sometimes dark-green, elongated and subpendulous. Very common in the coast- 

 district, but very rare higher up the Cameroons Mountain, already at the height of 600 — 700 m. 

 Very seldom fertile.

 only a small speeimen, seems to be identical with P. punctulatum,
