There is currently a problem with the PSI email servers and all communications to and from addresses [at] passiflorasociety.org are down. We are working to solve the problem, but don’t know how long it will take. Meanwhile, if you wish to contact PSI, please either use an officer’s personal email address, or submit a contact form. Many thanks for bearing with us.
This also means that those trying to register as basic members will not receive a verification email, and so will be prevented from registering. Please return later, or if you need to register urgently please submit a contact form, or email the registrar who is at passifloracultivars dot org.
Renewals and upgrades should not be affected, but if in doubt please also submit a contact form or email the registrar as above.

We are pleased at last to be able to announce provisional details of the twice postponed PSI Conference. It is to be held from 16th-18th September 2022 in the historic bastide city of Montauban in south-west France. Apart from the change of location from St Jory, the format is substantially the same as originally planned. Details will be found here.
Through all the ups and downs of Covid 19, Christian Houel has been battling on to ensure that PSI members will eventually be able to meet again in the usual way, and we are enormously grateful to him. Even now we cannot be certain that it will be possible, but we hope to take a final decision in April, at which time a new registration form will be posted so that members can register their interest.

We are pleased to announce that we have now started populating our reference library. We aim eventually to include as many authoritative articles on Passifloraceae as we can, prioritising those which are hard to find.
It is organised by authors, so that in some cases a file will focus primarily on one species, in others on many.
Please let us know of any particular authors or articles which are missing which you would like to see added. If you have copies of such articles yourselves which you can send us to upload, please do let us know.
You will also find copies of many articles under the various journals
In accessing any articles from the reference libary and elsewhere on this site, you undertake to use them for your own private study and research, and in most cases you will need to login as a premium member first.

Whoops ! Stefania Mattiuzzo’s beautiful new cultivar (Register #246) was misspelt in the register just published; this was almost entirely my fault as Registrar, for failing to ensure the proof was double-checked: I present to her my humble apologies. Its correct spelling is Passiflora ‘Gocce di Cielo’. The digital version of the register, which can be found here, has now been corrected, as well as the print version available for purchase on MagCloud here. To help any member who wishes to purchase the corrected version, the price will be held at cost price until the end of July.

In view of the continuing risks, restrictions and uncertainities relating to travel and meetings due to Covid-19, it has been thought wisest to further postpone the conference that would have been held this October at Saint-Jory in south west France to 16-18 September 2022. As before the conference will be hosted by Christian Houël, but will now be held at Montauban, a few miles further north, with the kind assistance of Les Fleurs du Sud. The structure will be similar, with Saturday 17th as the main day, with visits to the collection, meetings and dinner. A range of optional activities will be offered on the Friday and Sunday.
This is disappointing to all of us, not least to Christian who has put in so much work organising it, but we hope you will understand.
Further details will be announced in the autumn, when registration will reopen. Those who have already registered for the St Jory conference will be invited to update or cancel their registration as they wish.

Special thanks to Matt Candeias for his guest article on Adenia and to Markus Varga for his practical guide to this fascinating genus in the passionflower family; the sharp-eyed will discern a member species in his photo on the front cover, behind the foreground subject Passiflora edmundoi, which inaugurates our new series of Plant Profiles.
The first item in the issue is an update from your President and Vice-President, in which we ask you all (basic as well as premium members) to complete a PSI and Me questionnaire, to tell us what you would like PSI to be, and how you can help us get there! Please do take a few moments for this – unless you tell us, we may never know !

On 12th October, 2019 the momentous decision was taken during the Madeira conference to form a Voluntary Association under the name Passiflora Society International (“New PSI”), to dissolve the Florida corporation formally (and formerly) entitled The Passiflora Society International, Inc (Old PSI) and hand over its assets and activities to New PSI. Well, maybe not so momentous: very little has changed for you, the member, but it will make the society soooo much easier for its officers to run.

PSI was originally founded by Ron Boender in the United States of America and registered in the state of Florida, where its bank and other accounts were held
This worked fine while its management and members were predominantly US-based, but this is no longer the case, which has resulted in practical problems.
PSI is therefore being restructured as as an unincorporated association under English law, and two meetings have been called on 12th October 2019 to complete the process.
It is important that as many premium members as possible participate in these meetings whether in person, or by voting online.
Once the meetings have taken place, and the motions carried, premium members who participate, wherever they are based, should see no significant change in their membership terms and benefits; the same applies to premium members who do not participate and to basic members, except that they may need to confirm their registration the next time they login.
