112 H'JERiS UMRROSA.
F ro n d s lateral or terminal, adhe ren t to a b rie f creeping
rhizoma.
Sori continuous, ex tending to within an inch of the apex of
the segments, and along the d eourrent b a s e ; when young
green, afterwards reddish brown, and reflected over the edge.
Length of frond from two to th re e feet; colour splendid
b rig h t green. In my plants the h arron fronds are two feet
long, having a stipes one foot th re e inches in le n g th ; the
fertile fronds tliree feet th re e inches, having a stipes two feet
in length.
Stipes on the up p e r side flat and fluted, lower side circular,
colour of u n d e r side brownish, u p p e r side mostly g r e e n ;
da rk e r and scaly near the base.
Alv thanks arc due to Air. ITcnderson, of AVcntworth, for a

In very large species, it has been found impossible to figure
a whole frond without reducing it so materially in size, th a t it
is scarcely to be recognised; it has therefore b een deemed
more advisable in these instances to figure portions 011I3' of the
fronds.
T h e illustration is a portion of a frond from a plan t in my
own collection.
