The Ferns of South Africa. 
123. P. lanceolatum. Frond set with peltate scales, simple, lanceolate. 
— /3. sinuatum. Frond sinuate or pinnatifid. 
124. P. lycopodioides. Fronds dimorphous, naked, with a line of large 
medial areolae containing the sori in one regular line in free veinlets. 
Veinlets outside the areolae anastomosing irregularly. 
= /3. Mackenii. Larger, with a wider, flattened, paleaceous, epiphytal 
rhizome, and larger thinner fronds. 
125. P. Africanum. Fronds coriaceous, clothed on the underside or at 
first on both surfaces with stellate-pubescence. Sori numerous, small, 
scattered over the upper part of frond. 
126. P. irioides. Frond coriaceous, one to four feet long, without 
pubescence. Sori very numerous, scattered, minute. 
1 15. Polypodium proliferum. Presl. 
Plate CVIII. Natural size. 
Rhizome creeping. Frond thinly coriaceous, simply pinnate, 
lanceolate, two feet long, six to eight inches broad, with a naked 
stipe one foot long. Rachis and frond glabrous, or very minutely 
villose ; pinnae lanceolate, acuminate, sessile, from a rounded 
base, four to five inches long, one-half to three-quarter inch broad, 
cut along the margin about one line deep into rounded oblique 
lobes, with four to six pairs of veinlets meeting below the sinus. 
Veins conspicuous ; sori on the middle of the veinlet, often 
irregular or elongated as in Gymnogramme. Wood remarks — 
“A coarse-looking fern, having much the appearance of Nephro- 
dium unitum, growing in similar places, and often in company 
with it ; it is sometimes erect, and sometimes decumbent and 
rooting at the point, and is easily recognised by its habit of 
sending out long branches, which take their rise from an angle 
between the main rachis and one of the pinnae, no other Natal 
Polypodium having this peculiarity.” 
This species appears to be omitted by Kuhn, and resembles 
small specimens of Polypodium unitum, Hk.

Bkr. Syn. Fil. 315 ; Wood, Natal Ferns, 31 ; Buchanan’s List, No. 96;
