As Srieathagh ae this was sent to Dr. Brotherus, who named it 
T. ceylonensis, and wrote later that he had found a peristome 
present. There must have been some admixture, for the material 
Ih shows tr f peristome whatever in either old or 
ea 
distinct, the upper cells in 7. ceylonensis being shorter, 2 x 1 or 
subquadrate, and the leaf apex usually denticulate for some 
distance down. Here the upper cells are larger, and about 3 x 1, 
the leaf apex subentire, or denticulate so at point. 7’. Schmidit 
differs in the leaf apex very narrow, acute, and entire, the upper 
cells shorter, the capsule neck only equal to or shorter than the 
re the spores, according to Roth, also are larger (20-30 »)
