1 1 2. Nephrodium cicutarium. Baker. 
Plate CXLVIII. Part of lower pinna, natural size. 
This species can only be introduced here with some doubt, as 
I have seen no South African specimen of it, and it is not known 
at Kew from our area; but in Buchanan’s List (No. 5, page 30) is 
mentioned “ A Sagenia, apparently very near to if not a variety of 
Neph. cicutarium,” sent by Mr. Ayres from Macamac, Transvaal. 
The section Sagenia is characterised by veins anastomosing 
copiously, and as this could not be mistaken for any other plant 
here included, and as Neph. cicutarium is the only Sagenia 
recorded from continental South Africa, the following description 
and figure are given from specimens from Johanna Island, kindly 
forwarded to me from Kew. 
Frond deltoid, three-pi nnati fid, glabrous, thinly herbaceous 
but firm, with three to six pairs of pinnae, and a pinnatifid apex. 
Lower pinnae opposite, eighteen inches long, twelve inches broad, 
deltoid, stalked, cut to the rachis below, and to near the rachis 
above, into numerous, alternate pinnules, of which the upper are 
lanceolate, increasing from the point downward to six inches in 
length, one-half to one and a half inches broad, tapering to the 
acute point, and cut two to three lines deep into rounded oblique 
lobes three lines broad ; while the lower are six to nine inches 
long, three to four inches broad, and pinnatifid like the upper part 
of the pinna into rather distant, lanceolate, deeply crenate pinnules 
half-inch broad, and two to three inches long. Other pinnae 
gradually smaller upward. Mid ribs distinct throughout, other 
veins fine but anastomosing freely into rather irregular areolae.
