    Default Strange Castasetum??

    The tag says Catasetum tenebrosum, and it sure does not look like pictures of this orchid. I will say it has been a very strange Catasetum since I got it in March 2015, I remove the media from all my Catasetum and Cycnoches in the last fall and leave them in the shade bare root for their rest. Once I have about 3 inches with lots of roots I repot them. This one I did the third week of last month in sphagnum once more, I had used a different media the year before that I was sorry I had done so. This particular one started growing and only reach the height of about 2 inches when the top leaf just died, I decided that with all the new roots it was safe to pot. About a week later I saw what I thought was a new bulb that turned out to be a spike, I have a 2 inch tall pb that has a short spike with new blooms that have opened, they do not look like any Catasetum tenebrosum that I have found picture online. Any suggestions? Do I have an incorrect tag?

    The second picture is the latest new pb to grow with a little of the spike, the others are of the blooms.

    I think this is the rare hermaphrodite flower. The Cat' flowers most of us want are the male ones - they are the attractive gaudy things. The female often look the same from one species to the next, dumpy mostly green flowers. Hermaphrodite have a bit of each.
    If this post gets read by some of the more expert cataasetum growers, I think they will concur, and anyway. I will be interested to see what others think.
    By the way, male or female depend on the growing temperature at some point, so your plant may yet produce flowers you will like more - given some adjustment to your culture.

    The distinct male and female flowers of Catasetum do cause some confusion, with the showy male flowers and their longer spikes accounting for almost all pictures usually seen. I think the short thick spike here is fairly typical for female flowers of Catasetum tenebrosum. The heavy green hood and non-resupinate flowers are also typical, but the flowers themselves may not be so perhaps they are the rarer hermaphrodites. I don't see any reason to doubt the species identification. I hope a Catasetinae expert will respond and confirm.

    You need to wait for Ian to see your post.
    Defenetly looks like there is more female flower in it.
    They say with plenty of light it will give female flowers with less - male.

    Thanks for all of your comments, I have sent an email to Fred Clarke who is an expert here in the US, so I hope I will get some answers and will let you know what he has to say.

    I have heard back from Fred Clarke and he has no idea what had aborted the new growth, he thought I might have started to water them too soon but I did not. It is defiantly a female blooming!
