4. T. bilabiatum Nees et BI.; C. Chr. Ind. 636. 7. Filicula Christ, l.c. 
Differs from T. bipunctatum by its short-stalked, broad, deltoid 
fronds and by the presence of short spurious veins in the cell-tissue 
within the marginal spurious vein. The form collected is small, with few 
spurious veins.

5. T. siamense Christ, 1. c. 
Klong Munsé (no. 401). 
Christ incorrectly makes this a subspecies of J. rigidum Sw.; it 
resembles that species by its tufted fronds, rigid texture and brown 
colour, but otherwise it is very different, e. g. its rachis being distinctly 
winged throughout. Christ's description is somewhat inadequate. The 
lobes are not finely denticulate, but entire, the sori not 
free, but fully immersed to the mouth in an anterior tertiary lobe, 
leaving only a narrow margin of the lobe free as a wing to the sorus. 
The erect, short, branched rhizome is clothed at the growing apex with 
numerous dark-brown, cylindrical, articulated hairs. 
The affinity of this species is probably with 7. hispidulum Mett. 
from Malacca and Borneo. 
To this species probably belong some small tufts of a little young 
fern found in the jungle on rocks near Klong Munsé (sine num.). It was 
determined by Christ as 7. nanum v. d. B., Ghrist, lc. = 7. Kurzii 
Bedd., GC. Chr. Ind. 643, ‘but this, belonging to the subgenus Hemiphlebium, 
has nothing to do with our plant. Unfortunately, the small plants are all 
sterile, but in many characters: the tufted fronds, the hairs, the colour and 
texture, etc., they resemble very much 7. siamense, of which I therefore 
consider them to be young plants.

the species must be excluded.)
