Description
Growth-habit of T. lobbii but whole plant larger;
Distribution
Asia-Tropical: Borneo present
Malesia: Borneo (known only from the type collection).
Taxonomy
The irregular lobing of the frond apex and of distal parts of pinnae may indicate a hybrid origin, in which case T. lobbii is indicated as one parent, but there is no clear evidence of the other possible parent. Jacobs collected specimens of typical T. lobbii at a neighbouring locality.
