two of the second order are closed respectively at the level of the annulus 
and of the basal whorl of sporangiophores ; of the seven that enter the cone 
two are of the third, one of the fourth, two of the fifth, and two of the 
seventh orders. 
In Cone B of this species twenty-three meshes originate and are 
closed : thirteen of the first, four of the second, three of the third, two of

the fourth, and one of the fifth orders. Three more meshes originate in the 
upper part of the cone and remain unclosed. Of the eleven meshes found 
in the branch above the last whorl of leaves two, of the first order, are 
closed below the insertion of the annulus, and three, regarded as of the 
second order, are closed at or near the level of the lowest sporangiophores. 
Six of these meshes therefore enter the cone : three of the third, one of the 
fourth, and two of the fifth orders. 
In Cone C of E. giganteum eighteen meshes originate and are closed: 
ten of the first, six of the second, one of the fourth, and one of the sixth
