Monoicous, csespitose, small, green in colour. Fronds depressed, 

 creeping, flat, longer than broad, from a narrow base broadly 

 obconical, never distinctl}'^ furcate, sometimes spreading in a

Obs. — "This is the plant Dr. Spruce speaks of in his 'Hep. 

 Amaz. and And.,' p. 572, in a footnote. It resembles very much 

 our common Aiifli. 'pundattis in size, but may easily be distin- 

 guished by the frond creeping flat on the soil beneath, while in 

 A. pu/tcfaf/f.s it is almost erect, turbinate, rooting only in the 

 centre, the upper half alone being more expanded. Both have a 

 very thin frond, which appears streaked and reticulate if seen 

 from above, from the sub-epidermous caverns, which in the 

 younger parts of the frond are smaller and more distinctly

 and short scales, always arranged parallel to the axis and never
