Descriptions of the Species. 
191 
— Niphobolus, Auct. Under surface woolly. Species 125. 
§§§§§§§§§ Phymatodes. Presl. Areolae fine, copious, irregular ; the free 
veinlets spreading in various direction. Species 120, 121, 122, 123, 124, 
126. 
The other four sub-genera of the synopsis — Eu-phegopteris, 
Cyrtomiphlebium, Dictyopteris, and Phlebodium — are not repre- 
sented in South Africa, except the first, to which belongs 
Polypodium obtusilobum, Desv., which I cannot maintain, but 
which has been already noticed along with Nephrodium conter- 
minum, Desv. 
Key to the species. 
§ Stipe not articulated to the rhizome or crown. Veinlets of neighbouring 
pinnules uniting. 
1 1 5. P. proliferum. Frond pinnate, with lobed pinnae. Sori medial on 
the veinlets. 
1 16. P. unitum. Frond pinnate, with pinnatifid pinnae. Sori close to 
the mid-rib of the lobes, and situated on the veinlets. 
§§ Stipe articulated to the rhizome. Frond two-pinnate or two-pinnatifid. 
1 1 7. P. vulgare. Fronds without scales ; veins free. 
1 1 8. P. incanum. Frond clothed with peltate scales. 
1 19. P. ensiforme. Frond without scales, and with a line of large 
areolae each side the mid-rib, from which veinlets run to the margin, 
or again anastomose. The large areolae containing one free veinlet. 
120. P. Phymatodes. Frond without scales, veinlets anastomosing 
freely, and the larger areolae containing smaller areolse besides free 
veins. 
§§§ Stipe articulated to the rhizome ; frond simple (except 123 / 3 .). 
121. P. lineare. Frond one-half to one foot long, without scales. 
Veins anastomosing freely and irregularly. Sori sunk, placed in a 
medial row on each side of the mid-rib. 
a. Frond herbaceous ; rhizome long. 
/ 3 . simplex. Frond larger, thinner, veins more distinct. 
7. Schraderi. Frond small, coriaceous ; rhizome short, tufted. 
122. P. normale. Frond one to two feet long, without scales. Sori 
superficial, scattered, or sometimes in an irregular line near the
