THE FERNS OF SOUTH AFRICA 
winged upward, entirely without wing in the lower half, and 
bearing alternate pinnae a third to half-inch apart. Pinnae 
deltoid ; the lower, which are largest, one inch long, and a 
half-inch broad at the base ; cut to the slightly-winged rachis 
into three to four pairs of pinnatifid pinnules with four to five 
linear segments, those above gradually less divided, and with 
the pinnules linear and undivided. Pinnules (or segments) 
half a line broad, one to two lines long, distant, blunt, and 
with entire margins. Sori terminal on the pinnules of the 
upper pinnae, about as broad as the pinnule, hardly longer 
than broad, with roundish triangular valves cut about halfway 
down. Not unlike H. tunbridgense , but with entire margins 
and terminal sori.

This species was till recently only known from South 
Africa by specimens at Kew in the Rawson Herbarium, from 
Pietermaritzburg, Natal (Sanderson, 1863), which I have been 
unable to see, but it is included in Swynnerton’s list from 
Mt Pene, Rhodesia (7000 ft), as his 6016, and a small frond, 
not fertile but apparently of this species, was sent me from 
Mazoe, Rhodesia, by Eyles as his 359, from 5200 ft alt.; 
description and figure are from Mauritius specimens kindly 
forwarded to me from Kew.
