@Calvin, @SOS,
I am not actually sure whether my plant is a typical filicornu. It could even be a hybrid: I wouldnt have a clue with what though.
* The shape of the labellum is not typical
* The petals are a little too round
* The leaves of the plant are more oblong and narrow on the typical form and the plant is more compact than the typical form
In any case, if anybody has any ideas what it might be, do let me know
