Fig. 29. D.asterothrix{Fée) C. Chr. Entire 

 leaf X *l!,: base of pinna X 1'/»; frag- 

 ment x 4; sporangium. (Linden 1878). 



From D. reptans D. asterothrix can be di- 

 stinguished by its size, never rooting apex, its soft- 

 hairy rachis and stipe, setose sporangia and its 

 whole liabit. The rhizome bears often under the 

 long-stalked fertile leaves a rosette of small sterile 

 ones. — The following specimens are very uniform; 

 several of them from various herbaria were deter- 

 mined by Dr. Christ as A. dissidens Mett., under which 

 name the Guatemalan specimens were distributed 

 by DoNNELL Smith.

Not essentially different from the type, but 



the basal pinnæ the largest (small, reduced pinnæ 



always absent), on longer petioles (2 mm long), 



stipe and rachis with fewer or no long soft hairs. 



Jenman describes the indusium as distinct; I have 



failed to find it.
