Rai,
There is no evidence of Cym
lowianum or Cym
lowianum var 'i'ansonii' that I can see in your flower due to the lack of the dominant
lowianum trait of a barred lip. Because of the veination, the slight fragrance, excesssively starry form and the apparently very narrow leaves, I suspect the Asian species Cym
sinense in the first or second generation, probably bred to a Standard Cym. It should have more flowers but the plant appears quite small.
As far as a definite identification, no way to tell. Just enjoy it but handle it more as an Asian species than as a Standard Cym. i.e. blooming more easily in warm climates.
