under this on the surface of the frond; but neither of these 
is perfectly constant. And the raised line on the surface of 
the frond is found in typical Phyllitis as shown by Fig. 3. The 
entire area between the fertile veins is usually elevated in Tri- 
phlebia; but this would be a most inadequate generic character; 
and it is not constant in any group, nor wanting in typical 
Phyllitis. The chlorophyll is often relatively wanting in this 
area, as it is under large indusia of many ferns in several tribes, 
and the nether surface is usually concave in such cases. 
At the lower end of the sorus of both Diplora and Triphlebia, 
the line of attachment of the indusium leaves the vein, and this 
contributes materially to the optical illusion as to the origin of 
the sorus. But there is nothing remarkable about this. It 
occurs in most or all of the related ferns, and in many of other 
groups (Cfr. Athyrium, Davallia, etc.). 
Coming now to the species of these ferns, I am convinced that 
there has been no less of an unnecessary multiplication than 
there has in the genera. 
Malay-Polynesian species of the group have been described in 
the following order : 
Scolopendrhim longifolium Presl, Rel. Haenk. 1 (1825) 48, t 9, f. 1, From 
Luzon. 
Scolopendrium Durvillei Bory, Dup. Voy. Bot. 1 (1828) 273. From Ualan. 
Referred by Hooker, Smith, Christensen, etc., to Stenochlaena. 
S. pinnatum J. Smith (1841) name only; Kze. Famkr. 1 (1843) 124. 
From the Philippines. Described from Camarines Sur; found from 
central Luzon to Mindanao, and reported in van Alderwerelt's 
Malayan Ferns from Borneo, Celebes and New Guinea. This is 
the type of Tripklebia.
