Plate 158. Nat. size, b Part of pinnule, with sori. 
Frond repeatedly dichotomous, and often with the central 
buds developed ; but the branches are all without pinnules, 
except the terminal ones, which are six to fifteen inches long, 
one to three inches broad, tapering both to the base and to 
the point, and cut throughout, almost to the rachis, into linear 
pinnules one line broad, one to one and a half inches long, 
undivided, with a wide base, and a blunt or notched, or fre- 
quently one-sided point. The lowest pinnule on the lower 
side is generally elongated, and sometimes lobed, while at 
each forking of the branches arise a pair of small pinnae, 
two to four inches long, one half to one inch broad, divided 
into pinnules like the terminal pinnae, or lobed or sinuated, 
especially towards the base, but with the lowest lobe also 
enlarged. 
Sori of six to eight capsules, surrounding a raised re- 
ceptacle, placed near the middle of a vein. The frond is 
glaucous on the under surface, and quite glabrous throughout 
on the Natal specimens, though abroad it is described as 
being sometimes densely tomentose, as well as changeable 
in cutting, but characterised by the small pinnae at the base 
of branches without pinnules.
