    I really like the green colour. I hope my catasetums will bloom soon.

    Well Bruce do you think these are female or male flowers? To me they look like female flowers, though my search has only turned up samples showing this one type of flower only.

    It is hard to say for sure. These could be the female flowers, but to me they looked like the male blooms, just not opened up all the way. Here is a shot of some catasetum blooms that are labeled as male:



    They look very similar to the ones in the photos of this thread, only they appear more open. The only reason I asked the question is that Catasetums are unique for the dimorphic flowers they produce. The male and female blooms are so different that John Lindley originally thought they were separate genera. I believe the female bloom is much flatter and more broad than the male bloom.

    Check out the description on: Jay's Orchid Photo Page

    He shows a couple of photos of a catasetum orchid with both the male and female blooms as well as what they look like after pollination.

    Also see this brief article on Sexual Dimorphism in Catasetum Orchids

    First I don't understand your mean, Bruce. But now I see and I looked on some site, then see my tree is male flowers, hopefully I will earn female flowers like a full pair. Thanks for your information.

    Thanks Bruce. I checked out both links and found them very informative. I have a few catasetums and almost all have borne male flowers which are extremely attractive. However only one, Ctsm Tuanku Zainab Petra ( Sumani x fimbriatum ) has consistently produced both male and female flowers, although never at the same time. Female flowers are produced, I believe (in the case of T Zainab Petra) when the temperature is higher than normal. The reason I thought the planiceps of Raika's were female flowers was because they are reminiscent of the female flowers of Tuanku Zainab Petra in both form and colour and the upside-down positioning of the individual bloom - plus there is the absence of the two hair-like appendage protruding from the anther cap of the pollinias that act like triggers to propel the pollinia. Of course my observation is confined to the characteristics and behaviour of Ctsm T Zainab Petra and may not apply to the majority of catasetums , and the flowers of the planiceps shown may very well be male flowers.

    Unfortunately I have no photos of Ctsm T Zainab Petra at the moment but expect it to bloom in a month or two and will post photos - hopefully showing both the male and female flowers. Incidentally the male flowers are light apple-green in colour with tiny spots and on the flower spike look like birds in flight.
