Perhaps most nearly allied to T. ardjunense, Fleisch. and T. subduri- 
usculum, U. Muell. The former is a smaller plant with leaves only about 
half the size, the margins not incurved-cucullate at apex, the cells much 
smaller, while the latter, which scarcely differs from 7. duriusculum, Mitt., 
has leaves much more curled and cireinate when dry, with a different apex, 
and the leaf-base widely expanded, The rigidly incurved leaves, not at 
all glossy at the back when dry, with a very acute, sub-tubular and sub- 
cucullate apex having the nerve very shortly and indistinctly excurrent, 
give the present plant a well-marked character.
