  1. Greetings, I certainly didn't mean to suggest that bisquamata goes dormant in my earlier post. However, it is my experiance that utric seeds have an endogenous dormancy that may be due to inhibitory agents and/or a rudimentry embryo. GA3 and other growth factors may help overcome the reluctance of most utrics to germinate. On the other hand, it may be that most utric seeds are dead. Seeds from tropical perrenials usually don't have the same type of longevity that seasonal annuals exhibit. They probably do not have the thick seed coats to keep the embryo from drying out that annuals have. To that end, I am experimenting with annual utric (mostly from Australia) and tropical utric seeds (Brazilian) and GA3 to see if seed viability is affected by GA3 treatment. I'm also working on chemical treatments with hydrochloric acid and acetic acid...we will see if that helps. Peace Damon
  2. Vic, Those are great photos! I think the consensus from other discussions on microcalyx boiled down to whether trap morphology conformed to what was in Taylor. It seems that the floristic characteristics for this section of utricularia are too fluid to rely on them for a firm diagnostic. Pull out a stolon and examine it under 20-40x lens on Christmas (while crossing your fingers) and hopefully you'll have microcalyx. Your microcalyx seems to closely resemble the examples under dispute, but again the only way to find out for sure would be to examine the traps. Check out the following site for pics of many different terrestial utrics: http://www.plantarara.com/carnivoren_galer...utricularia.htm The microcalyx shown there looks very different from the examples shown on the humboldt.edu site. Which may mean nothing at all if the pic isn't of microcalyx either! I have obtained four specimens from different sources and whittled down two of them based on trap morphology...the other two appear to conform to Taylors description. I'm hopeful, but I think they may be livida also...we will see. On a side note...I read somewhere that microcalyx flowers have a pleasant odor. Is there any smell from your flowers? Peace and good luck, Damon
  3. Zongyi, Utric seed can be extremely difficult to germinate. Current advice is to start with very fresh material and to spray the seeds daily under bright lights. That being said, bisquamata is a bit of a weed in most collections and seems to have a high viability rate. I am experimenting with gibberillens to see if that will help break dormancy in other utric seeds. Difficulties stem from determining an effective concentration and finding a good source for fresh seed. Hope that helps...
  4. Greetings, My start of aureomaculata came from cpUK member tim who runs the following site: www.islandnet.com/~tmalcolm/. This plant is the collection favorite...even with no flowers! I got this start in September and it is currently growing very fast. It has a lot of aerial stolons (nothing as aggressive as blue sandersonii) and is in the process of spreading out in all directions. I keep it cool (between 75 and 60F) in a very sandy mix and brightly lit (4 40w fl). After another month of growth I'm going to repot and try different conditions. BTW, did you see any of these plants in flower when you collected your specimens last August? Peace Damon
  5. Tamlin, I too believe that the culprit lies in the peat. I have had limited success in controlling outbreaks of foreign flora by pouring boiling water over pre-moistened medium. It is a hassle...it makes me wish I had an autoclave handy :!: Please let me know how the milled LFS works out. For now I will combat the moss with constant vigilence and the repotting advice suggested in your post. Peace, Damon
  6. I grow my utrics under four 40w flourescent bulbs that are suspended six inches from the grow area. I have yet to notice any ill effects from growing them this way. I use bulbs that are closer to the red end of the spectrum and this seems to help (me at least) get blooms. Also, I have several utrics growing outdoors in full sun (bisquamata; cornuta; sp Hermanus; livida and monanthos(and of course subulata)). The leaf stolons were damaged because I didn't acclimate them correctly. But they all grew back nicely. They flowered quite a bit when SF had a heat wave a few weeks back...now there is nothing but dried up scrapes. One of my utrics that doesn't appreciate high light would be longifolia. I had a typical variety that had nice long stolons (about 7 inches) and I moved it to my high light area which caused the leaves to blacken and die. It now only has tiny little stolons. Peace, Damon
  7. Cole, Fortunately I don't have that problem. Mine started as a bright green, slightly sticky covering over the medium in pots of utric starts. I tried to scrape it off, but it would just come back. Some of the stuff is coming up through the sand, making the grains stick together. The sand makes it easy to scrape off...so that seems to be working form me now. I'm not sure what I will do when the plants send stolons up in that area. Right now I'm really leary of chemical remedies as utrics seem to be among the more sensitive CP's. Plus, it is quite a time investment to nurture a plant from a small start to where it is established enough to bloom (not to mention gifted plants that would be very hard to replace). I am experimenting with 2% hydrogen peroxide in a bisquamata pot. It keeps the moss at bay, but the plants isn't thriving either. We will see. Peace, Damon
  8. Greetings all, I had a bright ideal and would like to know if anyone thinks it would work. I thought that it would be possible to simulate the natural conditions that many epiphytic utrics grow in by constructing a tube of chicken wire and filling it with orchid bark and LFS. The tube would sit vertically in a pot of sandy peat that would be exposed to the normal utric watering regime. I’d love to know if anyone doesn’t think this is worth trying (and why). Possible candidates for this treatment are alpina, endresii, or nelumbifolia. Peace, Damon
  9. Greetings, I tried the coating of sharp sand over the exposed soil. The plants seem to appreciate it...I've noticed severa tiny stolons making their way out from underneath the sand already! Furthermore, my aureomaculata (the well-being of which has become a minor neurosis) has started to send out several little aerial stolons...I take that as a positive development indeed. For the past two weeks I've been getting some off-shore winds and I think thay brought several nasty moss spores my way. Peace, Damon
  10. Tim, It seems that even a wayward breeze is enough to spread the tiny seed. Tamlin's admonitions are spot-on, to call subulata vigorous or determined would be a compliment (and probably far more generous than you will get from most people). It still is an interesting species to cultivate and very pretty. Peace, Damon
  11. The sharp sand solution sounds like a good bet...I'll try that right away. Damon
  12. Greetings, I'm running into a problem that I have never encountered before and I hope that someone here has a solution. So here it goes: Moss is starting to run rampant in my utric collection. I'm not really worried about the species with (relatively) large and sturdy stolons. But my cultures of weltwitschii. firmula and something called sp. Zimbabwe could easily be overwhelmed if the infestation runs its course. Despite soil mistings that border on religious fanaticism, I still get a little mat of bright green moss. Is there a product out there that kills moss only? Any hints would be greatly appreciated. Peace Damon
  13. Also, there is a great website that shows aquatic and terrestial utrics in habit and bloom. Check it out at: http://www.plantarara.com/carnivoren_galer...utricularia.htm and http://www.humboldt.edu/~rrz7001/Utricularia.html The plantara wesite is pretty straightfoward (even if your german is rusty). Peace, Damon
  14. Hey Tim, There are a few utrics that might fit that description....praelonga, prehensilis, subulata, and any number of the aquatic species. Do you have a decription of habit? I'm always interested in utrics, even the homely subulata :) peace Damon
  15. Vic, The picture is stunning! This is the first time I've seen such a clear pic of tricolor. Truly well done. Peace Damon
