 dle, reversed, radiated at top, in two rows, on the back of

 minute.

 scattered, naked spots. 



GLEICHENIA Capsules three or four together, sessile in a 

 little hemispherical depression of the leaf. 



ANGIOPTERIS Capsules sessile, naked, placed in a double

 mersed in the frond, with two rows of cells, opening at 

 the top. 



** Capsules of one cell, with two valves.
