jointed hairs. In some specinv:ns， they are also emitted near the 

 upper portion in a somewhat concentric manner. The frond is com- 

 posed of two layers of cells which are arranged in a single longitudinal 

 row of an equal breadth in surface view," In soiiie cross-sections we 

 often meet with cells of the both sides divided into two by a partition 

 parallel to the surface (Fig. 15). "Cells of the under-surface are a 

 little larger than those of the upper. Sori are found not fully formed 

 in the specimens now before me ； but some of cells beneath the line of 

 innovation are divided into 4-6 or 8 in double rows, taking an ap- 

 pearance very much resembliru 丫 to the anthericiia illustrated m J. Ap".
