Cover photo from September 2010 CPN issue containing the article Rembold, Katja, Andreas Irmer, Simon Poppinga, Heiko Rischer and Gerhard Bringmann (2010) Propagation of Triphyophyllum peltatum (Dioncophyllaceae) and observations on its carnivory. Similar studies should also be done for Africa. All thw flowers there must have been male then which is unfortunate. I just need seeds :/, Harris has a unfair advantage of living in Malaysia. If this event happened 20 to 35 million years ago simple within-landmass dispersal would be sufficient to stage the species near where their future homes would appear. The classification problems could be inadequate description of the species. Even if we assume they were there and are now lost or not found yet, a date this old is not concordant with the fossil dates or with the pompom configuration of the phylogenetic tree. King of Spades was a large male cultivar with dark colored pitchers that Rob found from those original seed and has used in breeding. What they do indicate is proto-Nepenthes-like plants were abundant along the northern Tethys Sea in what is now Europe and southwestern Asia. Nepenthes require high humidity. For all we know, the fossils could all be representatives of totally extinct lineages. The data used for this tree are chloroplast trnK gene intron, matK sequences from Heubl, Meimberg, and associates (see references) greater than 2000 bases long and deposited with NCBI. Drosophyllum apparently adapted to the changed climate in Europe by losing all the no longer useful liana characters and taking the form of a full-on sundew. Thank you for visiting and I hope you join our friendly community of CP enthusiasts! We ship this plant potted. Specific details of the phylogeny could change with additional species or analysis with a different program. The stem, leaves, and pitchers have a sparse indumentum. Nepenthes plants produce either male or female flowers but not both. Unless seeds are desired and one each sex is available, consider removing any flower spikes, as they will draw energy from the plant. This can be done by dabbing the male flower on the female flower or shaking the male flower over a piece of paper so that ripe pollen falls off on the paper. I cannot promise how fresh the pollen will be on arrival, but we will do our best. On a female plant, flowers are equipped with carpels (female reproductive structures), and on a male plant, flowers hold pollen. It appears there were two or more introductions into the Malay/Borneo region or if it was one introduction there was a split into at least four branches soon after. Until there has been time for the gene frequencies to reach an equilibrium, male sterile (i.e. Growing brand new Nepenthes from seeds is effective, but will take years for a new plant to mature and flower. There is nothing primitive about this species relative to other Nepenthes species. During periods of low sea level such as during the recent Pleistocene ice ages it is quite possible Nepenthes species spread across the land bridges. I have a Perfect plac to germinate neps i would have them under a daylight bulb 25*c day 20*c night 90% humidity day and night. Nepenthes pervillei on the Seychelles Islands between India and Africa. The green arrow points to the stigmatic surface. The data used for this tree are chloroplast trnK gene intron, matK sequences deposited with NCBI. We often get asked about Nepenthes flowers because Nepenthes are either male or female and you need one of each to make seed. Of course more interesting hybrids are preferred, but I'm looking to get some experience growing Nepenthes from seed so I … It is not clear Nepenthes inflorescences fit any of the strict definitions exactly but panicle is closest. Partial peduncles are bracteolate and two-flowered. 8:821-830. Pl. The most basal species of the Nepenthes phylogeny is Nepenthes distillatoria. Clarke, C. M. (1997) Nepenthes of Borneo. The chloroplast phylogenetic tree for Nepenthes is consistent with an initial population of Nepenthes in India and/or southwest Asia that gave rise to the species now in Madagascar and the Seychelles via long distance dispersal. The only way to tell them apart is by the flowers. Journal of Paleontology 48(3):565-567. Germinating Nepenthes seeds is not difficult, provided that you have time, space and fresh seeds. Pitcher plant is a fascinating carnivorous plant that has ornamental appeal while entertaining and educating on a unique method of feeding. Nepenthes are dioecious, that means there are male and female plants.

A little is known about how to evolutionarily get from from having both sex flowers to single sex flowers. If you have ever handled the seeds or tried to make seed packets you will know they get everywhere. The evolution of dioecious flowers must have happened before any of the currently known species came into existence. Nepenthes switched from having hermaphrodite flowers to being dioecious. (2006) Plant Biology 8:831–840. Ancistrocladus did the same to become quite widespread across Africa and southeast Asia including areas where Nepenthes is found but not necessarily immediately after leaving Europe. It would be interesting to know if N. mirabilis has special adaptations to facilitate migration or if just being in coastal swamps is enough. male) and thus not put the energy into seeds that will not contribute much to the next generation. Since many Drosera species in Australia are self-incompatible it is likely the ancestor of this whole group was self-incompatible. They have two wings that grow on either side of a central ovary. So how could all this movement happen? Nepenthes alba growing on the bleak, windswept summit of Mount Tahan on the Malay Peninsula. Of course the species will commit suicide if all the plants are male sterile or female sterile so the system needed to evolve with a proper balance and controls for there to be Nepenthes today. To produce Nepenthes seeds, you will need to pollinate the female plant with male pollen. when or if you smell it So if the explosion of species in Sumatra of the clade with N. lavicola at the base resulted from the rise of the Barisan Mountains, both isolation between populations on new mountains and the generation of new habitats gave great opportunity for Nepenthes to create new forms. The female parent of this release has the cultivar name ‘Queen of Hearts’, and is very probably the most photographed Nepenthes in history, having appeared on many of BE gold medal winning Chelsea Flower show exhibits. Miller, J. S. and Venable, D. L. . The red arrow points to the narrow column between the anthers and the sepals. All of these known species are separated from the actual ancestor by many genetic changes in matK and presumably other genes but in terms of what makes them a Nepenthes there is nothing to make one think they are "ancestral" just looking at them. I say mostly sterile because with a small probability they produce aneuploid gametes that when the right combination unites, produce offspring of a higher, more stable, fertile ploidy level. 38(4) p. 105. When two samples of the same species were included in the analysis, the one with the best quality sequence was selected for the figure. It is apparent that in the 35 to 65 million year old time frame it is difficult to link the pollen fossils to existing genera so we end up with, "well, it is most like Nepenthes but it could be Drosera". Raceme appears to be used most for inflorescences typical for Drosera where the flowers open in a wave going up the stem—never mind Nepenthes does that too but it is more subtle. Several small flowers grow on a long spike. So a lot had to happen genetically to Nepenthes after its split with its ancestors. Nepenthes clipeata – Native Exotics – Clone 1 – NE-107 – Very Rare Nepenthes seeds are typically wind dispersed. It is of course possible two or more seeds will hitchhike to the same place at the same time. If they then produced male flowers we will have proved, probably for the first time, that Nepenthes can trans-gender. The pollinators of some species seem to be flies and moth, but beetles, bugs and ants are also observed to visit the flowers. For this phylogenetic analysis we are using the chloroplast trnK gene intron which contains the matK gene. (2010) Carnivorous Plants and Their Habitats: Volume 1 and Volume 2. Care was taken to exclude the translocated matK pseudogene sequences in the figure. If female it might produce seeds without pollination but they should be clones and thus females as well. In the wild Nepenthes are fly pollinated and the flowers smell like it. Left: Fully paniculate inflorescence of Nepenthes pervillei (photo © Urs Zimmermann). Miller and Venable (2000, 2002) found an example of such a transition in the genus Lycium (Boxthorn, Solanaceae) facilitated by polyploidy. This has undoubtedly happened many times in Nepenthes so a phylogenetic tree produced from nuclear genes would probably lay out differently from the tree above which is based on chloroplast genes.
