    Actually , getting the duller peculiar female flowers or the brighter more distinctive-shaped male ones, in catasetums and their close allies is supposed to be related to temperature or light , I forget which, but so far of the ( less than a dozen, I have to admit ) species I have flowered, I have yet to see a female flower - or the rarer hermaphrodite spike, with both kinds on, which I have only ever read about.

    First, thanks Ian for the pics of the whole spike. Looks very impressive.

    Re the female flowers. My Cstm Tengku Zainab Petra ( I have already posted pics of it) produces female flowers quite readily, usually after a rise in temperature during the flowering season.I've had this plant for more than 30 years but unfortunately have not seen fit to take pictures of the female flowers....they, being extremely ugly. The next time the female flowers appear i'll make it a point to photograph them .. just for comparison.Didn't know about the hermaphrodites until now. Just realised that this year Cstm T Zainab Petra must have produced 3 of them on a short spike looking very much like the female form except that they possessed the trigger-like antennae attached to the pollinia(like the male flowers) and also the two, spotted lateral sepals, which in the 'pure' female form exist only as vestigial sepals , green without spots. Again didn't take any pics. Regrets, regrets, regrets...What a missed opportunity !!!

    OMG!!! wow ....30years......i am speechless and amazed. seems like i got a long long way to go and still got many things to learn. haven't seen one hermaphrodite myself yet (dun take my word for this, i just started with catasetum orchid less than a year...hehehehe) but i had a catasetum once where the spike appears at the tip of the bulb and not from the base of the bulb.

    Most probably a catasetum intergeneric with either a Cynoches or Mormodes.

    maybe you are right...the plant if i recall correctly is ctsm penang red X ctsm Oo Oo
    penang red = catasetum pileatum x susan fusch (orchiglade x expansum) while orchidglade is ctsm pileatum X ctsm expansum

    but i really dunno what is catasetum serdang Oo Oo made of...any clue?
