I have an array of U.Gibba, Aurea and another aquatic in flower, I understand that Aurea and Gibba are the same species/section (Utricularia) so as others in their own sections have been hybridised (mainly the orchidiodes and iperu utrics) would it be possible to cross these two? I understand that their minute flower size will be an issue and imagine that this is the big thing that has stopped others from doing it. Otherwise has Longifolia (or prealonga) X Calycifida been done, as my calycifida has been flowering none stop for a few months and I am expecting longifolia to in a few months. Or bifida X uliginosa (oligosicta). Any advice would be greatly appreciated (from those whom have actually done this before or actually know what they are talking about)

I know there have been a couple cases of species crossed outside their own sections, though still within subgenera. I would assume it is possible as well, as there are a couple of species thought to have arisen from hybridization, such as if I remember correctly, ochroleuca. If it is possible though, I would bet it will be difficult to get any real results, as Utric seeds are notoriously difficult oftentimes to germinate, the only exceptions I know of being the weedy species and the Foliosa section.

Gibba and Aurea are weedy species here, my gibba flowers year rounds, but my Aurea only flowers for a few months of the year, but aurea make up for it by spreading so fast via offcuts/cuttings.
I am not sure if their seeds germinate easily, but pretty much every local swamp/river has Gibba in it, and most have Aurea to.
I know Bifida and Uliginosa seed germinated readily for me as they invade pots here, worse than Subulata, but again they are native.
I will try it and see what happens, who knows it could make a super weed that will need to be contained, or it may already exist in the wild here and just e classed a form?

Won't know if it will work unless you try, I guess. Best of luck to you!

I was hoping to hybridise my Gibba and Aurea to make a super aquatic, but this has proven harder than I though as my gibba has made over 50 Cleistogamous flowers this month, and not one true flower, it is only one variety of gibba that originated from a swamp near dads place (North QLD) that is doing this, it has never flowered for me until now (over 2 years on), I have another gibba from a swamp just 10-12km away that flowers none stop and has never made these faulty flowers, so are they genetic, is this a nw species/variety or is it just bad luck. My other gibba are all in ponds back at dads and my flowering aurea are all here in Townsville, pain in the @r$e. Sorry I can't attach images, I have placed them on another forum, as I have always had trouble posting pics on here. theauscpforum.lefora.com/topic/19398153/Gibba-Cleistogamy#.U0CWFrDNuP8 |

Thanks for sharing. I didn't know gibba made those kinds of flowers. My gibba doesn't make anything at all.

... so as others in their own sections have been hybridised (mainly the orchidiodes and iperu utrics) would it be possible to cross these two? I'm not certain who could answer such a question definitively. Even failing with crosses isn't definitive. I have attempted a number of crosses - some successful & some not. Some of them I have tried multiple times & figured that the cross doesn't work - then I find out that someone else has done the cross successfully - doh! Bob Z keeps his eye on what is happening in CP land and if he finds out a cross has been made - he posts the pics on his photofinder. Also - view people's claims of success with some skepticism as some are bogus or not yet certain. A European vendor had a cross (maybe longifolia x alpina) that look suspiciously like the result of a selfing. In fact, my claimed cross of U. asplundii x jamesoniana may also not be valid... Otherwise has Longifolia (or prealonga) X Calycifida been don Check Bob's photofinder Any advice would be greatly appreciated (from those whom have actually done this before or actually know what they are talking about) I've done a number of crosses but that doesn't necessarily mean I know what I'm talking about.  Even within the Orchidioides, I find that many of the species either are not receptive to crossing or my specific clones are never in the mood. What specific advice are you looking for - how to physically do the crosses or ...? |

I was thinking of using a small piece of wire for the process, as a toothpick seems to large for such minute species (the gibba and Aurea), I am guessing it is like pollinating orchids (as their flowers seem similar) which I have done before with a few of my orchids, I figured I would have to do several attempts to ensue it works (if at all), but this shouldn't be a problem as my Aurea should be flowering for a couple more months yet, giving me atleast 50+ flowers, and if this Gibba variant doesn't give me a flower I will just have to bring another variety and induce flowering (which is super easy in Gibba).
I have seen a fair few utric crosses involving longifolia, reniformis and alpine that I have been sceptical about as they plants sometimes just look like a sick or malformed version (I have longifolia for example and if I grow it in the greenhouse it looks normal, but if I grow it in a terrarium or my polyhouse it looks like a new species).
I am obviously not expecting a gibba that is as broad stemmed as an Aurea, but I do think that in the same conditions as the parent the hybrid offspring will be distinguishable, which is all I'm after, and obviously I will have to contain it as both species are native here (but surly have separate pollinators that would prevent hybridism) and I don't want another break out. (I have had livida and subulata escape before so they are now in containment)

I was thinking of using a small piece of wire for the process, as a toothpick seems to large for such minute species (the gibba and Aurea) Removing the 'excess' flower parts that obscure the pollen & the 'flap' and your chances of success go up exponentially. By removing these parts, you will be able to see exactly what you are doing & not operating blind. If you do not do that, you are as likely to self-pollinate or not pollinate at all as get a successful cross-pollination. |

I was just going to use a magnifying glass, on Aurea the lower corrella is easily pushed down and out of the way, along with it the palate giving a pretty clear access point.
