  1. Darwin's carnivore experiment's-experiments/
  2. Petiolaris Germination Question

    Not so much bound by time of year. You will see your plants go into dormancy. In general I keep light and temperature the same but reduce the amount of water so they stand dry for a couple of days and then give a little...seems to work ok.
  3. Petiolaris Germination Question

    heat and humidty won't do any harm as long as you have enough light
  4. Petiolaris Germination Question

    I usually wait with picking out seedlings until they are at least 1 cm tall, better if there is space 2 cm. I accept that I will loose late germinating seeds at some point, though generally I carefully pick out the big ones, rest I let grow on which give some seeds a change to germinate. The holes in the soil generally don't pose a problem. Slime is probably algae and it can kill your plants, so I would deal with it.

    Rules of the Herbarium Visits to the Herbarium The Herbarium is open to researchers by appointment only. If you would like to arrange a visit to the Herbarium, please ensure you apply by email at least two weeks in advance* of your expected arrival and your email must contain the following information: Email subject: Please start with the word VISIT and the date of arrival and departure (e.g. VISIT 20 – 23 July 2016). Please note we are closed at the weekend and public holidays. Taxonomic groups: Please indicate all the plant families or genera you wish to look at. Region of interest: Please indicate the continent and/or countries you are interested in. Exact dates of stay: Please repeat this information, ensuring that there are at least two clear weeks from the email date to the date when you wish to visit Kew. Plant material: Please indicate if you intend to bring live or preserved specimens to Kew and what it is you are bringing in case permits are required, e.g. CITES. Please give yourself adequate time to inform Kew as permits may take time to issue. Your details: Please ensure you include your full name and full address of your institution or your personal address if you are a private researcher. Confirmation: If you are a student, please ask your supervisor to request the visit on your behalf to confirm that the research is required for your studies. * For overseas visitors requiring a letter of support for a visa application, please ensure you apply for your visa at least three months in advance of your visit. Visitors with potential commercial interests (e.g. a representative of a commercial horticulture company) should be asked to sign the non-commercialisation undertaking. Discuss with your line manager if you are unsure about how to proceed. Non-commercialisation undertaking (Word doc) If you read the document it says amongst other things: In particular, I agree that: § I will only use the information and/or images for scholarly, education or research purposes; § I will not sell, distribute or use, nor transfer the information and/or images to anyone else for profit or for any other commercial application; § I understand that copyright in information and images associated with the herbarium specimens is owned by Kew or by Kew’s licensors; § I will acknowledge the source of the information and/or images with the words “With the permission of the Board of Trustees of the Royal Botanic Gardens, Kew”; Seems clear to me...
  6. ICPS conference 2018

    Hi, For those of you who are not directly connected to the Californians and missed a shared post on the ICPS facebook page: A) There is conference information on this page: B) The registration seems to be working already though some info like the cost of the hotel is missing I have not received any information about this, so I know as much as you do.

    Relax, they are building the info pages, not much there yet. As soon as there is anything substantial I'll give everybody a heads up.
  8. Hello from Sunny South Africa

    Hi Riaan, Good to see you here
  9. Small addition on that. Of course it has strong promotional value but Bill is actually a good friend of Rob and that plus the combination of a thanks for his conservation work (in Bill's case Indonsesian rainforest and specifically Urang utan projects) os the main reason he was selected and not....say Bruce Dickingson. He actually came to see us at work at the IUCN-Carnivorous Plant Specialist Group redlist workshop and attended the presentation of a botanical painting to Sir David Attenborough at the ICPS conference. Same with Dame Helen Mirren.
  10. New Carnivorous Plant Book

    Publishers website has more information: check the table of contents and the contributerslist. Lots of big guns, but expect a technical/scientific book, like a selection of specialised papers on selected topics make a complete story. Not a picture book or light reading material. Looks like at least one of my Christmas gifts will have a slow reindeer...
  11. Nepenthes clipeata Cultivation Survey

    The ICPS project is more or less silent as there are not many registrations done. However we are still working. Last year a match was made and seeds produced. The seeds got distrubuted. Ark of Life got some which went to the Hortus in Leiden for the Nepenthes Ark we have there. As a matter of fact..if any one has a male that is going to flower about mid november - mid december please contact me. I know a lonely female in Japan that will be flowering at that time. The beautiful lady in question is living for many years now in a botanical garden and was originally wild collected by that botanical garden.
  12. Rare Nepenthes project

    Hi Mathias, As Stewart has so little time we are re-setting things as a foundation in The Netherlands with an actual international board running things (as opposed to a not for profit organization with only Stewart on the books). Basically we are already a foundation (notary work is done). Right now the bank is checking the identification papers of the first 3 board members (Tim Bailey, John v.d. Werf and myself, others have agreed to join the board and will be added when things are running) so an actual bank account will be available and not just a paypal account linked to Stewart. With that Chambe of commerce can be completed. After that...we need to reactivate the dead website. It was frozen after many hacks, so we need to rebuilt that more strong. When that works I can meet the requirements for Charity status and we are off again. For the moment the plants in Leiden are doing well and we had some additions since this last post. Check out our Facebook page for that
