  1. "S. 'Tina' Here is the cultivar we selected for its beauty. Rare, it comes either from a crossing involving Sarracenia purpurea ssp. purpurea f. heterophylla (a form with no red pigments), or a variety which has not been officially described. Just like Sarracenia flava var. rugelii, the leaves are light acid green - a rare characteristic among plants - with one or several red spots under the hood, making it strongly attractive to most flying insects. As any Sarracenia purpurea, it is a very cold-hardy carnivorous plant." Hmm, there are several odd things in this advertisement... "Light acid green" being just like rugelii, really? "Strongly attractive to most flying insects", come on man... It reads like they are just making it up. And it has, apparently, already been named as 'Sorrow', so much for it not having been described.
  2. Well, I think is this clone C plant, but I don't know what was bred together to make clone C. Looks like it could be just straight purp, but the petioles seem a little too long... Whatever it is, it really is a nice looking clone. There aren't any natural hybrids between "venosa" and "purpurea" as they are the same species or if you include S. rosea into S. purpurea, the same subspecies.
  3. I've been out looking at S. purpurea in the field for fifteen years. You can literally find venosa like plants right next purpurea like plants in New Jersey, Delaware, Virginia (not there are any left at this point, but I did get to see some before they went extinct), New York, Pennsylvania, Georgia and Indiana. There is no clear division in S. purpurea between the northern and southern populations. There is, however, a big separation between S. purpurea and S. rosea. They are not connected and haven't been since long before people started altering water tables and other habitat reduction schemes... Though I do wonder if some of the mountain purpurea in what is considered the southern locations for S. purpurea montana might be intermediate in nature... But none of them have the short and pale flowers of S. rosea. The only way your venosa look more like S. rosea then they do S. purpurea is because they are S. rosea which were mislabeled as S. purpurea venosa somewhere in their past history and this used to be common practice in horticultural circles. :)
  4. I have not reviewed every single plant from every location, but I strongly suspect there is only one location for S. purpurea var. montana, but other locations have perhaps different kinds of purpurea... I also don't support the idea of separating S. purpurea into two subspecies as the differences between purpurea and venosa are just plain nonexistent... I wonder what went into that purp hybrid "C"?
  5. Well, there are four clones from Wistuba and two or three from Borneo Exotics. But I think these first clone batches were grown from seed collected from the same female plant, or at least from the same location. These plants *should show* very little differences as they are all siblings or cousins to each other--but hey not a problem for me as they all look really nice. Just wish there had been a female in the bunch...

    ID please

    Looks like P. emarginata and 'Sethos' to me... Of course, photos of the leaves help a lot too.
  8. Hello Seaman, I have grown seed of the same cross you mention, but the plant is not "thorelii", more likely it is N. kampotiana or one its very close relatives. So this name is more accurate: "Nepenthes sp. Phang Nga * N. kampotiana?" I don't know if it might N. thai instead of N. k.... The seed I received was grown by a fellow named Nong from Thailand. His "thorelii" is also from Thailand and so cannot be N. thorelii as this species is from Vietnam and has never even been found as far north as Cambodia.
  9. Well, my deposits don't taste sweet either... (what a phrase! lol)
  10. No, it seems to happen randomly to plants. There is a photo of N. khasiana in McPherson's new book which also has a "salty peristome". I don't really understand what is happening that causes this. Looks similar to honey which has become sugary...
  11. Because it should be making nectar; not the odd salty, sugary material...
  12. Hey there, And just the other day I was wondering if these two species can hybridize...

    ID Help

    While the plant in question cannot be ID'ed using the photo presented, it certainly is possible to ID a Nepenthes plant, especially in person.
  14. The hairest species: N. albomarginata, N. argentii, N. chaniana N. glandulifera, N. hurrelliana, N. hispida N. hirsuta, N. fallax (some call it stenophylla) N. peltata, N. petiolata, N. pilosa N. veitchii, N. villosa N. maxima is not particularly hairy.
  15. I seen this happen, seemly randomly, on a couple other plants. N. platyhila for one. Not sure wh this happens. I hope my plant grows out of it.
  16. Most likely the plant which could not finish growing its flowers was either heat stressed and/or nutrient deficient.
  17. Dear Andreas, Great photos! Is this _Schizaea_ growing behind the sundew?
  18. Dear Simon, There has only been one plant found, ever. It is male. Some folks visited the plant and removed parts of it. Perhaps they took samples to grow or to make herbarium specimens so it could be named.
  19. I can see how pure water, right at the surface of the liquid in the pitcher might be able freeze without any of the plant tissue or even less pure water deeper in the pitcher would not thanks to chemicals which lower the freezing point. But still, I think this would be pushing it and maybe too far. Local people may have seen this happen, but maybe the rosettes died later anyway and the plants regrew from roots...
  20. Well, we agree with you :) Anyway, D. filiformis var. tracyi is different from D. filiformis var. filiformis in several respects, not just coloration. The leaves have a different shape and so do the traps. It is not a separate species, however, nor a subspecies as the ranges of both kind of thread-leaved sundew overlap.
  21. Nope, this is the one and only known plant of its kind. This thread is the recording of its discovery. Rather cool, huh? BTW Jonathan, those bird do look awesome. I'm not much of a birder, but I do enjoy looking at them.
  22. Ah; maybe Manders, maybe not. Unfortunately urban legends aren't confined to the cities... I don't think I'll be "volunteering" any of my plants to a cold weather test ;)
  23. I agree, I think these varieties and forms are just normal variation for the entire species. Some populations may display more of one characteristic than other populations, but I don't find these differences to carry much taxonomic importance...
  24. Regardless of the infection type, the basals might not yet be infected. The longer they stay on the plant the more likely they will be infected though... Take the cuttings, keep them separated from each other and your other plants. Watch, wait and see what happens...
  25. Hello Chris, I really doubt this would be the reason for difficulty in making seeds... I don't have another theory though...
