stem ; while in plants developed in more confined and 

 humid situations, they are longer, less rigid, and more 

 spreading. 



The fructification is, in this species, not borne in ter- 

 minal spikes, as in the other kinds, but is produced in the 

 axils of the leaves along the upper branches of the stem. 

 The spore-cases are rather large, sessile, kidney-shaped, 

 two-valved, and filled with minute pale-yellow spores. 



Besides the ordinary spores, the plant is furnished with 

 other means of propagation in the shape of deciduous buds, 

 produced for the most part in the axils of the leaves, about 

 the apices of the branches. These buds separate spon- 

 taneously, fall to the ground, and there vegetate, first pro- 

 ducing roots, and then elongating into a leafy stem. They 

 are formed by an altered leaf, which, becoming somewhat 

 swollen on the outside, protrudes from its inner margin 

 five small lanceolate leaves or teeth, the whole beinir 

 elevated on a short hardened footstalk. Mr. Newman 

 describes these changed leaves as becoming transformed 

 into irregular six-cleft calices or cups, the outermost lobe 

 of the six being longer and larger than the rest, and of the 

 pair on each side, one being generally incumbent on the 

 other, so as to nearly conceal it. Within this is a whorl of
