This species is probably the form mentioned by Blanco in the original descrip- 
tion of Gimbernatia calamansanai, as differing from the original form, which was 
collected in Laguna Province by Azaola, in its broader fruits, G. calamansanai 
having fruits (including the wings) “mas de una pulgada de ancho v media de 
alto,” while the other form mentioned has fruits up to two and one-half inches 
wide. The specimens cited above seem to represent a form that is constantly 
distinct from typical Terrninalia calamansanai, recognizable by its much larger 
leaves, larger fruits, and its pubescence. All the sheets from Rizal Province bear 
the native (Tagalog) name Calamansacat.

This species presents several forms, which may eventually prove to be of 
specific rank when more material is available for study and comparison. The 
typical form is represented by specimens bearing fruits (including the wings) 
about 4 cm wide, and 2 cm long, as in the following specimens ;

Curran, specimen in flower, from Zambales, is probably also referable here.

are here indicated as varieties of T. calamansanai :
