 smallest specimens a minute spur just under a single spore-case terminating 

 the short stem ; in larger plants an oblong entire bract, lower on a stipe 

 bearing a few sporangia ; in ordinary forms springing from below the 

 middle of the stipe, short-stalked, 'half an inch long, once incised or parted 

 more or less deeply, with its fertile spike branching at base ; in the largest 

 specimens rising from the stipe near the root, long-stalked, an inch and a 

 quarter in length, three-fourths of an inch broad, four times pinnately 

 divided, the lowest lobes separate from the higher and all enlarged at the 

 end, its fertile frond terminating the long stalk, two inches in length,
