    I may as well start a general thread instead of cluttering this section with posts for one pic at a time. My U. "Nüdlinger Flair" has flowered!

    Hello everyone, last spring I had my first sporophytes on Sphagnum. They appeared on Sphagnum fimbriatum, a monoicous species. This means a single plant can produce both male and female reproductive cells (Both eggs and sperm cells). In order to have sporophytes on the dioicous Sphagnum species, you will need both a female and a male clone, but not for this S. fimbriatum. I decided to do a little experiment and grow Sphagnum from spores. While looking in the literature I read this article: 'Habitat requirements for establishment of Sphagnum from spores' (Sundberg et al., 2002). The authors found out that Sphagnum spore germination is limited by nutrients (phosphate). This means that Sphagnum spores germinate on places where there are more nutrients then where adult Sphagnum plants occur (usually nutrient-poor soils). I decided to do the experiment in three different setups. 3 small containers with blonde peat that has been cooked to kill all spores present. In one I added fertilzer but no spores, in the other I added spores of S. fimbriatum but no fertiliser and in the last one, both spores and fertilser (really low amount) was added. The experiment started somewhere halfway june 2017. Now we are 5 months further. Cooking the peat seemed effective as no growth is observed in the container without sown spores. Also the outcome of this little experiment is perfectly in line with Sundberg et al.: not a single spore germinated on bare peat without any nutrients available. This is how the containers looked like 5 months ago: How they look like today (the container on the bottom contains nutrients and spores, in both others not a single plant appeared) They are still not looking like adult Sphagnum, but last week I could watch them under a microscope and they show the typical characteristic hyaline cell structure like any other Sphagnum, so now I'm finally sure it's not a random moss. Now I'll show some pictures from the development of the little plants. Sporophytes are almost ripe, 7th of June First germination a month after sowing: these are really small thallose protonemata from Sphagnum fimbriatum, 17th of July Growth of the protonemata 2 months after sowing, 14th of August Development of the gametophyte on a protonema, 28th of August Young gametophytes, 11th of October Young gametophytes of S. fimbriatum 5 months after sowing, 4 months after germination, 14th of November. I consider this experiment as over now, but I might add a picture once the plants shows adult characteristics of S. fimbriatum. Enjoy the pictures, I had a lot of fun following up these little creatures!

    Hi, last year I wasn't very active and so I haven't even posted the pictures from the end of last season. Here are the pictures of my tuberous drosera from April 2017. Starting with Drosera aff. bulbosa Caballo Blanco form Drosera yilgarensis Drosera whittakeri A young Drosera lunata Drosera zonaria from Oakford Drosera lowriei "Gigant" Drosera aff. palladia south coast form Drosera stricticaulis The Lakes Two pictures of Drosera squamosa Drosera rosulata gigant swamp form Drosera rosulata gigant hills form and a Drosera rosulata without location Drosera purpurascens Not the most fascinating picture ever but a plant that is not so often seen in culture: Drosera prostrata. A flowering Drosera obriculata Will be continued. Best regards from Berlin Lutz

    Thanks, and indeed Karsty, that is what the authors of the article propose. They tried out natural resources of phosphorus like moose dung and birch litter, both setups gave germination. Contrary to big seeds, small spores don't have a reserve amount of nutrients with them. It isn't too surprising that they need some help to get started.

    I have no idea why this hybrid does so well in my flat, does it just do well for everyone indoors? Out of 12 different Nepenthes, this one is simply the most consistently happy (~8... https://photos.app.goo.gl/yIqksO3ukUBizlM22 https://photos.app.goo.gl/ytrbTuo1tibl3AKn2

    I don't have a link, try google, Peru has limestone in its geology. The only way to know if its a benefit is to try it. My memory is one guy wrote he had small peruvianums growing on the mortar in his greenhouse...

    Just been looking at my spore collection in the fridge, I have about 25 different packets, some of which are over 20 years old, I think I will grow them all out next year to see whether they are viable ( I have grown Pityrogramma from 11 year old refrigerated spores a couple of times in the last 20 or so years!)

    Well heres a couple of photos taken with my phone camera down the eyepiece of my microscope! As you can see the sporangia are very dark brown and the spores (a few visible almost in the centre of the second picture) are pale straw coloured. Interestingly not very many sporangia with ripe spores, which may be because it is a hybrid (hybrids typically produce lots of small white spores and a few large typical spores, or none at all), or maybe just drought at the time of formation...Like your superbum, mine is now producing the spore patches on the fronds that will give next years sporangia.

    Looks like it. They are very pale though, mature spores of most ferns I have looked at have been brown or yellow. However I don’t know what colour veitchii spores should be (I will check my lemoinii later and let you know Sent from my iPhone using Tapatalk

    grandiflora does need a cold rest period,to help it flower.If its too warm over winter it will eventually die. they can stand being frozen solid outside.it will do it good and won't kill it

    That’s not likely to come to much, it throws small plantlets about 2 or 3 inches across which establish easily and don’t weigh a lot! Sent from my iPhone using Tapatalk

    Yes I have a low power binocular microscope so I had a look with the x20 lens. It does suggest that, normally when I collect spores I check for ripeness and then put a cut frond on a piece of paper overnight. If the spores are ripe all the sporangia will release the spores onto the paper. If not ripe you get very few or no spores. That superbum sounds spectacular! Platycerium are quite tough and tolerant of low humidity. My Lemoinii is in a too small hanging basket in my unshaded greenhouse and gets very little water all year around, less in winter. It has fronds about 50 cm long and is clumping up vigorously, every few years I chuck the whole thing away save one offshoot and start again...

    Certainly the hybrid Lemoinii, (which has veitchii as one parent ) is happy in dry sunny conditions and tolerates the cold . However the gametophytes will need moisture to grow, but as you say may well need extra sun. I would tend to suspect unripe spores though as inspection of the dried contents of the spore package showed very few free spores, and lots still in the sporangia. That suggests the sporangia have been scraped from the frond surface, rather than allowing the spores to release naturally. Time will tell Sent from my iPhone using Tapatalk

    This time there will be few more plants that are appearing here for the first time. Heliamphora nutans (Kukenan Tepui) Very flat growing form of this species - growth habit which isn't amongst my favourites :) Heliamphora x [exappendiculata x ionasi] - M. Stelmach clone 3 Very nice hybrid and my first clone to reach maturity. I'm curious how big it will get. Heliamphora exappendiculata (Amuri Tepui) Typical form of exappendiculata from Amuri with atypical coloration :) You're getting some shade soon Exie, no worries! :) Heliamphora "Clash of the Titans" The hybrid which is supposed to be quite famous but I find it pretty unpopular. The parents are H. ionasi "Killer Giant 1" and H. tatei. It's not very big plant at the moment but I'm expecting a monster. Heliamphora elongata "Bubble Lid" (Karaurin Tepui) Today's highlight I believe and surely one of my favourite helis already. While I like them slender and compact, this species matches these preferences, but only in certain conditions - when it's freezing cold and windy on Tepui. Otherwise leaves are growing more freely and have slightly different shape. That means H. elongata is heterophyllous - the only Heliamphora species that does such thing :)

    Hi everyone. As others have said, the HCP open day was fantastic - many great plants on display, and Matt was very welcoming to all the visitors. All my photos from the day are in a gallery on my website, in case anyone's interested: https://www.carnivorousplants.co.uk/blog/gallery-hampshire-carnivorous-plants-open-weekend/ Tom

    This is what three months of growth looks like. First picture taken on day of planting: Darlingtonia in a white pot with peat/perlite, and some Sphagnum heads on top of it, pressed into the peat. The pot has no drainage holes, hoping to keep it wet easily. The Sphagnum loves it, and I hope the Cobra loves it too. May 13th 2017 August 4th, 2017 I try to keep the cobra above the moss, if needed I'll pull out some of the moss but for now I just push it back from time to time.

    Carl, I think on a specialist site like this we do need to ensure that we use correct terminology otherwise people may finish up using silly kindergarten terms like "leaf-pullings" etc. Stephen is currently in abstentia so someone has to say it

    I'm pleased you both managed to get hybrid seed, what species was crossed with the Cephalotus ?

    Popped to the greenhouse today and noticed the lids on my Hummers Giant are bent right back, almost vertical to the pitcher. The photo's don't show it as clearly as I'd hoped but that's iPhone's for ya !. I've not seen them do this before so thought I'd post a couple of pics.

    Hi Mike, I noticed something similar to you--I sowed some of Stephen's Cephalotus seeds in September 2011. Half of them I put outside in a growhouse and the other half I put in my [warm] terrarium. In December, the ones in the terrarium had started to germinate. I then brought in the ones from outside as it was getting quite cold (as in below freezing) and they also started to germinate. While I note this is a small sample size, I won't bother stratifying any Cephalotus seeds in the future.

    A lot of people don't stratify their seeds and still get good germination...

    Dear Members of the CPUK Forum, Since my last post a few weeks ago, I have been travelling across the great island of Sumatra, photographing Nepenthes and other plants. One of the species at the top of my list to photo in the wild was N. aristolochioides – one of the most unusual and interesting species of the genus. With two friends, I was fortunate in travelling to the type locality – the widely known, original population of this species. The total number of individuals of N. aristolochioides was always known to be low – I believe approximately 100 or so individuals constituted the entire original population at the type locality – the original site where the plants was known to occur. Collecting by foreigner tourists and locals over the short history of this species has really taken its toll. I was told at the location that last year, the mountain was climbed and stripped of plants. According to local guides just one single specimen remains at the original population which is a terrible blow to the wild population of what is surely among the most interesting of all the pitcher plants. This story highlights how vulnerable so many CP species are to poaching and how, as CPers we must all refrain from collecting any plants from the wild. The Sumatran Nepenthes are particularly vulnerable since so many species occur across such geographically restricted areas, often on just one or two mountains. The case of N. aristolochiodes does has some hope. Fortunately two smaller populations have since been discovered away from the original site. Both are completely extremely difficult to reach and are located within Sumatran Tiger habitat (which relatively few tourists trek through). The populations at the larger of the two groups amounts to, at most, just a couple of dozen individual plants, and fortunately appears to be extremely seldom visited. It seems safe, at least the medium term. Even though the population of N. aristolochioides at the type locality has already practically been wiped out, the species will hopefully endure through the two smaller populations which appear to be much more secure. It is however, a worrying reminder how vulnerable CPs in the wild can be, and how we all should only support responsible retailers and not those that take plants from the wild! Anyway I hope you enjoy the following pics of this remarkable species; Best regards to you all Stew
