This species is very similar to T. acuminata, Baill., in general 
subcordate. The inflorescence also is pear-shaped or ellipsoidal, not 
globose, and evidently much larger, as the measurements given above 
are from the largest inflorescences on the specimens, which are evidently 
amens have only grown to about $rds the length of 
the perianth. This has lanceolate acute lobes, whilst in 7. acuminata 
the perianth lobes are rounded or subtruncate.
