CXLIII. FILICES. 467 
TriInE 9. EUPOLYPODIE. 
Sori without an involucre, globose or rarely suboblong, 
placed on the back of the segments, dorsal or terminal on the 
veins. 
25. POLYPODIUM, Linn. 
Characters of the tribe.— Hook. and Baker, Syn. Fil. p. 804. 
Polypodium, Goniopteris, Marginaria, Pleopeltis, Phymatodes, 
and Niphobolus, Pappe and Rawson, p. 39-41. 
A very large genus, and variable as to habit, and veining. There are two 
principal sections, viz. Phegopteris, with fronds like those of the Aspidiee, 
stipes continuous with the caudex, and sori always medial on the veins ;— 
and Eupolypodium, in which the stipes is jointed at the base, and the sori 
usually terminal on the veins. The first section is represented at the Cape 
by 2 species of subsection Goniopteris, which has the veining of Hunephro- 
dium. Of the subsections of Kupolypodiwm, there are— 
Subsection Lupolypodium proper. Veins all free.—3 species. 
Subsection Goniophlebium. Veins forming ample uniform areole, with 
the sori terminal on single free veinlets in the centre.—1 species. 
Subsection Niphobolus, with matted fronds, and a more complicated 
venation.—1 species. 
Subsection Phymatodes. Fronds not matted, veins uniting copiously 
and irregularly.—5 species. 
TrizpE 10. GRAMMITIDER. 
Sori linear or linear-oblong, without an involucre, dorsal or 
marginal. 
96. MONOGRAMME, Schk. 
Fronds like small leaves of grass, with only a central mid- 
rib. Sori in a line close to the midrib.—Hook. and Baker, 
Syn. Fil. p. 374. 
The simplest in structure of all the plants of the Order. 
1 Cape species. 
27. VITTARIA, Smith. 
Fronds grass-like, with copious, lateral, free veins. Sori 
linear, continuous, marginal. Pappe and Rawson, pp. 38, 53 ; 
Hook. and Baker, Syn. Fil. p. 395. 
A. single Cape species. 
28. NOTOCHLZANA, R. Br. 
Fronds ovate, compound. Sori marginal, at first oblong or 
subglobose, soon confluent into a continuous marginal line.— 
Pappe and Rawson, p. 42; Hook. and Baker, Syn. Fil. p. 370. 
4 Cape species, 3 of which are very rare, and nearly or quite endemic, 
the other probably identical with a plant common round the shores of the 
Mediterranean.
