Stereochilus ???????

[cxcanh]

This plan look more like Cleisostoma brimanicum (much much bigger than dalatensis, and flower is the same Stereochilus dalatensis. The spike always go down not go up like dalatensis.
Do anyone know exactly what it is?

It's hard to tell without a picture of the plant.

cant help with the id, but can see the differences to your dalatensis, which has side lobes and different petals, also the anther looks more prominent.
