This is the plant Dr Spruce speaks of in his Hep. Amaz. 
and And., page 572 in a footnote. It resembles very much 
our common Anth. punctalus in size, but may easily be 
distinguished by the frond creeping flat on the soil 
beneath, while in A. punctatus 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 subepidermous caverns, which in the younger parts 
of the frond are smaller and more distinctly reticulate. The 
epidermis of both bears numerous little crests and short 
cales, always arranged parallel to the axis and neve 
running across. The frond is — as usual in the genus — 
repeatedly forking, the forks however are not divided and 
free (as in some exotic species) but connate with ea 
other by means of a thin lamina; a cross section of t 
plant shows therefore 4hin and thick parts regularly 
ternating, the thicker being the costa, which also bi 
uch larger caverns, lying over a solid base of unbroke 
ssue, In both species the frond is running out into
