A metaschematic flower. 
Our specimen shows in complete accordance with a few species 
of Alpinia a highly interesting displacement of the parts of 
the flower. | 
1° Calyx: the two lateral sepals /ree and showing the shape of a 
normal un-paired sepa). Position bilateral. Direction downward. 
2° Corolla: an ordinary petal in the place which in normal 
flowers is occupied by the lip. Two coalescing petals on the 
top of the flower. One of these petals has the shape of a label- 
lum. If the metaschematic displacement had been complete, 
both these petals should have displayed the shape of a lip. 
° Column somewhat indistinct. 
4° Two staminodes, most probably belonging to the inner whorl, 
i.e. the normally polliniferous ones. 
5° Anthers two, covering the place of the two of the theoretic- 
[os 
ally outer whorl.
