A graceful scandent, but we should scarcely call it, as Kunze ‘ 
does, a“‘ twining” Fern ; having assuredly its pinnules very much — 
resembling those of Adlosorus cordatus, figured at Tab. 4698 of © 
our last volume: nor can we point out any specific difference, _ 
but that the latter has an erect habit, while this is flexuose in 
the main rachis, and quite zigzag in the secondary ones. For the 
character of the genus Pellea, M. Fée places reliance on the 
colour, ete., of the stipites and principal nerves, black and shining, — 
ete., as in Adiantum ; whereas his first species (the same as ours) _ 
and his second, or Pel/ea sagittata, are peculiarly pale, almost 
Straw-coloured, in the stipites and principal nerves. It isa 
native of Peru and Mexico, and flourishes in a temperate Fern- _ 
house, requiring support in its cultivation. eee 
Descr. Our plants are from four to five feet long; the rather 
short stipes and main rachis being flexuose, more or less downy, 
with soft patent hairs ; secondary rachises, or branches, long and 
straggling, often pendent or refracted, these are glabrous, or 
scarcely downy, singularly zigzag or angulato-flexuose, bearing —
