Cycnoches blooming habit is very much like that of catasetum. From my observations, sex of the flowers is mostly dependent on light intensity … NOT AMBIENT light intensity necessarily, but specifically light intensity on the buds, at a certain developing size.
If ambient light is VERY strong (maybe 4000-5000+ foot candles, or 50% shade in very strong light) & the flower spike & buds are exposed throughout the blooming process, flowers are very likely to be all female (the not so beautiful flowers … sorry ladies). On the other hand, if the plant is in a much shadier place, the male flowers would occur.
If the plant in a shady location has some male flowers open (with some still unopened buds) and is moved into bright light, the buds, that are 1/4 or 1/3 mature, will develop into female flowers … on the same spike. Some of the buds, in the middle of the spike, which had started to develop into male flowers, may develop into bi-sexual flowers. So there might be 3 types of flowers on the same spike.
Previously, I mentioned the distinction between intensity of ambient light & intensity of light on the developing buds. For example, two plants are in the same STRONG ambient light conditions. One plant is hanging by itself or sitting by itself. This plant is likely to bloom female flowers (few flowers only). If the flower spike of other plant is heavily shaded by leaves or by other plants in close proximity, it is more likely to develop a longer spike of male flowers. Both plants are in the same greenhouse. But the developing spike & buds of one are under very bright conditions. The spike & buds of the other are under very shady conditions.
By moving a plant from very shady to very bright, the developing buds can easily shift to female buds. I have not seen the reverse happen. Moving from very bright to very shady will not change the sex midway in development … probably because the strong light has already irreversibly affected development.

Thank You for taking time to give us important information about this orchid plant.
I got male flowers again for the second time around, the light from the corner of the windowsill must be doing it....
I got this orchid plant four years ago so the people I got it from must have acquired it maybe 12 years ago since they gave me three canes to start with....
