the first order (cf. pp. 252-3). The remaining seven persist into the cone, five 
being of the second and two of the third orders. Of the eighteen meshes 
arising above the last whorl of leaves thirteen are of the first order, being 
closed in the neighbourhood of the insertion of the annulus. Of the 
remaining five three are of the second order and are closed near the level of 
the lowest whorl of the cone, while two, both of the fourth order, persist 
into the cone. 
In Cone B of the same species twenty-two meshes arise and are closed : 
six of the first, four of the second, three of the third, three of the fourth, 
two of the fifth, and two of the sixth orders. Five meshes originate above

the annulus ; one only is of the first order and is closed just above and 
between the insertion of two of the sporangiophores of the basal whorl of 
the cone. Four persist into The latter, three being of the second and one of 
the seventh orders. Of the fourteen meshes arising above the uppermost 
whorl of leaves nine are closed near the level of insertion of the annulus and 
are, therefore, of the first order. Four of the second order are closed at the 
level of the lowest fertile node, and one, of the fourth order, extends 
upwards into the cone. 
In Cone C of E. hyemale twenty meshes arise and are closed : five of 
the first, eight of the second, two of the third, one of the fourth, and four of 
the fifth orders. In this cone eight meshes arise above the level of the 
annulus; one, of the first order, is closed just above the level of the lowest
