pale, deciduous scales in which case they are also found on tl: 
rachis ; branches stout, sometimes in several tiers, curving ar 
branching repeatedly ; segments thick in texture, with smooll

toothed ; rachis rough with raised points as in C. medullaris. 
will be observed that the fronds differ from the latter in texti
