Ramuli simplices vel dichotoine aut pinnatem divisi ad 

 apices obtusi. 



The form differs from the variety in the obtuse character of

 in an otherwise exposed position. It is curved in the upper 

 part and measures 7i centimetres. The ultimate branchlets 

 measure a little over 1 mm. in length.
