Type. Cerro Sta. Ana, Paraguana Peninsula, Edo. Falcon, Venezuela, Curran & H a m a n 672 (holotype G H ; isotype U S ) .

This species is found mostly in the Guayana Highland, with a few collections from coastal Venezuela. It differs from the closely related T. trigonum var. fimbriatum (Backh. ex Moore) Proctor from Trinidad in having relatively broader, subdeltate rather than oblong-lanceolate laminae, in having crenately lobed rather than sublacerate pinna segments, and, according to Weatherby, in having cell lumina only 0.05 rather than 0.1 m m in diameter.
