A few of my Ctsm species....
First up - Catasetum stevensonii - this is a small plant for the group and this was it's first season for blooming. I got a female spike first and then several weeks later it popped another spike that was male.
First - female flower -

Male flowers -
Mormodes skinneri (another favorite!) this one opens yellow and ages to white. It's a small plant that produces a lot of blooms. I had 4 spikes at this time and it's since pushed out 2 more spikes.
A shot of some showing the color difference -

Once all the flowers had been open a few days -
Catasetum sanguineum
I'm not a big fan of this flower but I like the upright spike so I keep it.
Cycnoches pentadactylon
Mormodes rolfeana
I had 2 spikes on it this year but they weren't open at the same time. This is the 2nd year that I've lost a couple of buds on each spike so the flower count isn't great but the flowers themselves are huge.
