160 ANNALS OF THE ROYAL BOTANIC GARDEN. CALCUTTA. Metroxylon. 
The “Sagu molat" is without spines, and corresponds to that bearing nearly 
the same name (malat) from Amahai; all the others are referable to M. Rumphii ; 
of these “Sagu Tuni” (var. micracanthum) differs from the type more than the 
others, by its very small fruits, but “Sagu Makanaro" (which I have also reduced 
to var. micracanthum) forms a transition to the varieties with larger fruits. The 
“Sagu puttih” of West Ceram slightly differs from the “ Sagu puttih " of Amahai.
