The cortex curls backwards and outwards from the apex, formin 
an oblique collar with its edge turned ‘inwards. The obliquity 
(which varies in degree in different branches) is owing to more 
rapid formation of sporangia and paraphyses on one s side than on 
the other ; the axis of the cone thus comes to be noncoincident with 
that of the branch.
