    G'Day everyone,

    I went on a fieldtrip today in the hope of finding some native Australian Utricularias in flower. Ended up finding huge colonies of U. dichotoma and U. tenella both in full flower. It was quite a windy day but the flowers managed to stay still long enough to get a few good shots. This is a few more photos than I would normally add but I wasn't sure which ones to leave out. Hope you enjoy seeing these plants in their natural habitat.

    Firstly, a shot of the habitat of U. dichotoma. You can see many of the purple flowers. This area is a small depression on the side of a walking track in a flora and fauna reserve in the middle of Melbourne suburbia. The water was around 10 cms at its deepest and slowly beginning to dry out as summer approaches-

    Next, a shot of U. dichotoma flowers sticking up out of the water-

    A picture of a bunch of flowers growing amongst reeds-

    Three flowers growing close together-

    A nice robust double header-

    A flower spike growing up against a Drosera aff. peltata plant-

    And finally a double header of Utricularia tenella. If you look carefully you can see Drosera peltata plants in the background. These plants grew in soil that was just moist and not submerged as U. dichotoma prefers. It may pay to take these growing conditions into account when you grow these species yourself.

    Also present in this area close by were many plants of D. peltata, D. auriculata, D. aff. peltata, D. whittakerii ssp. aberrans, D. pygmaea and D. glanduligera.

    Regards,

    Sean.

    Nice photos as always Sean. Have you ever observed a pollinator for U. tenealla? My plants will not self seed, despite being annuals. Since the plants produce seed in habitat there must be something there doing the deed.

    Thank you so much! I have almost no feeling for what the natural habitat of my plants is like, and it's great to get a guided tour, so to speak. Your photos of the flowers are incredible, too.

    Great job!

    Hey Tamlin, I've never actually seen the U. tenella flowers being pollinated but whatever does it is extremely efficient. The plants we found in this area numbered in the millions, nearly all had been pollinated with seed capsules forming. The only insect that I could imagine to be present in great enough numbers to achieve this is some type of ant. There are many present in the area.

    The U. dichotomas also had many flowers that had been pollinated and I'm not sure what the pollinator for these would be either. It couldn't be ants as the plants grow in water making it impossible for the ants to get to them. Next time I see these plants I'll make sure I take a closer look to see which insect is responsible.

    Regards,

    Sean.

    I am pretty sure that a small beetle did the pollination here on my outdoor grown U. dichotoma. I really have to learn some way to pollinate these plants by hand: as it is I am going to lose both species of "Polypomphlox". U. multifida flowered already: wonderful flowers they were too! U. tenella is close to flowering size now, and that will be a first for me.

    Sorry for this off topic question, but have you ever seen either a pink or a white form of U. dichotoma in habitat?

    I have seen white U. dichotomas in flower several times. During the trip I took these photos we saw a single white flowered dichotoma that hadn't quite opened up yet. Another day later and the picture would have been on the forum.

    I am visiting a spot on Friday which is extremely rich in CPs- U. dichotoma and D. binata forms in particular. I have seen many white flowered dichotomas there in previous years. The dichotomas found in this area grow mainly on granite rocks in the millions, they really are an awesome sight. I plan on adding a few photos to the forum next weekend. I know you'll be impressed. I'm really hoping to find U. beaugleholei, lateriflora, tenella and violacea as well while I'm in the area.

    I don't recall ever seing a pink flowered dichotoma but I've seen every shade between white and deep purple. I'm on the lookout though.

    Regards,

    Sean.

    Hello, Thanx for the pics.

    I always thought U. Dichotoma was pretty plain and rather ugly but your pictures have changed my mind. The dichotomas in your pictures are very pretty little skirts. I might get some for an Australian CP terrarium I'm planning to put together when I divide my cephs.

    Man I can't wait to see you next pictures. Good luck on finding some U. Violacea! I hope you take requests, I would really love to see U. Multifida and U. Simplex, hope you can find some of those too. [img]http://www.**********.com/iB_html/non-cgi/emoticons/biggrin.gif[/img] Thanks so much

    Well if I have made one extra person appreciate the charm of these beautiful little plants then I am a happy man.

    I don't like my chances of getting any shots of U. simplex or multifida in the near future. The problem is that they grow on the other side of the country- about 5000 kms away. Something like from NYC to LA. Hopefully next year I'll be over there.

    Regards,

    Sean.
