Sébastien Houyelle and Christophe Quénel, well-known explorers of the
Madagascan flora, telling readers about the rediscovery of Euphorbia boinensis,
a species that has been thought of as extinct, since it has never been
found for almost 100 years. They show us pictures of the plant in
habitat that most likely nobody has seen before.
> Rikus
van Veldhuisen and Pjotr Lawant introduce readers to Euphorbia subgenus
Euphorbia section Rubellae - a small group of geophytic euphorbias from
Tropical East Africa, including such beauties as Euphorbia brunellii, E. rubella, E. cryptocaulis and E. charleswilsoniana.

Schnabel starts his series on hardy euphorbias for northern gardens with portraits of E. characias, its subspecies and varieties. An Euphorbia
that flowers like an orchid? Yes, there is one, and Rikus van
Veldhuisen introduces it in beautiful pictures. Pjotr Lawant tells
about two newly described Euphorbia species: E. gokakensis (from India, closely related to E. caducifolia) and E. seshachalamensis (from India as well, but a tuberous species allied to E. meenae and E. fusiformis). He also summarizes a paper on the dispersal of dendroid Euphorbia species on the Canary Islands. Massimo Afferni also looks at a very special Euphorbia species from the Mediterranean: Euphorbia spinosa - that isn't spiny at all! Don't

Issue 12(1): preview
Issue 1 of Euphorbia World Vol. 12 is in print now
with some exciting new contributions:
For more than a century secretive Euphorbia
caput-aureum has been the "holy grale" for botanists
exploring the Euphorbia
flora of Madagascar. Nothing else was known of this mysterious species
than a description and a locality that could not be traced anymore.
That is, until Christophe Quénel set out to search for it - and found a
most beautiful species with cyathia arranged to form a "golden head".
In Euphorbia World he reports on his quest and shows us the first
photographs of this species that had been lost for so long.
During the Euphorbia World Convention in 2015,
I.E.S. President Susan Carter has given an inspiring lecture on Euphorbia
from Somalia illustrating her wealth of experience with East African
Euphorbia species. For all of you who could not attend the Convention
Susan has written a comprehensive text illustrated with beautiful
pictues showing our favourite subject: succulent Euphorbia.
Not
so long ago Rikus van Veldhuisen has been on botanical excursion in
Aethiopia with some fellow plant ethusiasts. In this issue he
summarizes his numerous encounteres with plants that might be
Euphorbia borenensis (or something new). Very worth
studying!
In Detlef Schnabel's series of papers on
Euphorbia polygona and its varieties, one of the main
difficulties was that there was no population of Euphorbia
polygona var. horrida
(once Euphorbia horrida) known to science anymore - despite that fact
that many collections hold plants labelled that way (whatever they
really are). Now var. horrida has been found again in habitat - and
Detlef shows us the TRUE Euphorbia polygona var. horrida!
In
issue 11(3) of Euphorbia World we started a series on Brazilian
Euphobias. Now Otávio Marques, Inês Cordeiro & Ricarda Riina
report
on Euphorbia section Crossadenia
- a group that includes Euphorbia appariciana, E. crossadenia, E.
flaviana, E. goyazensis., E. gymnoclada, E. lycioides, E. sarcodes, E.
sessilifolia, E. teres and the recently described E. riinae.
Don't miss out this new issue of Euphorbia World -
and besides: It is the first one with increased number of pages!

Issue 3: preview
Issue 3 of Euphorbia World Vol. 11 is in print now
with some exciting new contributions:
Ricarda Riina, Otávio Marques & Fernanda
Hurbath start a series on Euphorbia from Brazil.
In part 1 these autors give an overview on the section Brasilienses,
best known for its succulent species Euphorbia phosphorea,
E. attastoma, E. holochlorina and E. sipolisii
- including a table of morphological features helping to correctly
identify these species.
Euphorbia
World editor Volker Buddensiek and Alfred Razafindratsira, well-known
explorer of the Madagascan flora, describe a new succulent species from
the red tsingys of Madagascar: Euphorbia ramena.
I my opinion one of the most beautiful euphorbias ever discovered on
this treasure island.
Speaking of Madagascar: Bob Potter will contribute
beautiful pictures of Madagascan Euphorbia taken in habitat.
Gerhard Marx once again shares his passion for
medusa's head Euphorbia, sorting out the many errors around Euphorbia
crassipes including confusions occuring around E.
fusca and E. decepta. Very worth
reading carefully to increase your knowledge of these species.
Finally
Massimo Afferni once again invites readers to follow his excursions to
the Canary Islands in search of rare shrubby Euphorbias.

Euphorbia World Vol. 11(2)
has been published
Issue
2 of 2015 is out and on its way to members. Apart of some impressions
of the Euphorbia Convention in Meise (see below) it has two major
publications: Gerhard Marx and Rikus van Veldhuisen have finally solved
the question of what is the medusoid Euphorbia brevirama,
coming up with some surprising insights and adding two new varieties to
this mysterious species. The other large paper is part two of Wolfgang
Ewest's review of geophytic Euphorbia from Chile,
including Euphorbia thinophila and Euphorbia
copiapina. Again he adds a new species to this group of
interesting plants: Euphorbia cyanofolia Ewest.
Last but not least our Chairman shares some of his
pictures of his latest travel to Ethiopia. Very much worth seeing!
Back
issues of volumes 10 and 11 of the Euphorbia World are only available
by subscription. So if you do not want to miss these papers you may

Impressions from the
Euphorbia Convention in Meise
The
Euphorbia Convention at the Botanic Garden in Meise (Belgium, May 16
& 17) was definitely was a highlight for those attending the
Convention. Not only because of a number of most interesting lectures
given by the most renowend Euphorbia specialists but also because of a
unique chance to exchange knowledge, purchase new plants and to visit
the superb Euphorbia collection of the Botanic Garden in Meise. You can
read a short summary and see some pictures of the event here.
For further pictures please have a look at our facebook
pages.

Official programme of the
Euphorbia Convention online
The
official programme of the Euphorbia Convention taking place at the
Botanic Garden in Meise (Belgium) from May 16th to 17th has been
finalized and is ready for download!
The number of participants is limited - but there
are still a few tickets left. Book fast
- the Euphorbia Convention celebrating the 10th anniversary of the
International Euphorbia Society is very much worth visiting: from a
once-in-a-lifetime line-up of lecturers such as Susan Carter or Norbert
Rebman to the opportunity to visit the phantastic Euphorbia collection
of the Botanic Garden Meise that usually is not open to the public.
See you in Meise!

experiences with "difficult species" and intensive care!
Al
Laius has travelled Zimbabwe and takes us on his trip with some
pictures in our "In habitat" section. Finally Wolfgang Ewest gives an
overview on geophytic Euphorbia from Chile
including the description of two new species: Euphorbia
melicae Ewest and Euphorbia crypta
Ewest. In part one of his two-part-paper he also portrays the
little-known Euphorbia porphyrantha.

September 2014
Looking back at the AGM meeting 2014 at
Blankenberge:
On
Saturday, the 13th
of September, the Annual General Meeting (AGM) of the I.E.S. was held
at the International Plant Fair (ELK) at Blankenberge. The meeting was
opened by our Chairman Rikus van Veldhuisen. All Committee members
needed to introduce themselves because of the great number of members
that was present that day. This was the best meeting yet, there were a
lot of familiar faces, but as important, a lot of new faces as well.
The interest in our Society by the members is growing every year.
After
the minutes of last year were approved, the brief reports of the
Committee Officers could start. Membership Secretary Pjort Lawant got
some good news that our membership account was developing well. We even
have a National Representative in Madagascar now. After this news it
was no surprise that Bob Potter, our Treasurer , could state that the
I.E.S. is doing well financially. If membership fees are paid in time
there will be no problems in near future.
Volker
Buddensiek, editor of the I.E.S., reported that we have a limited
amount of articles for future issues of ‘Euphorbia World’. Most
articles keep coming from members who made trips to Africa, Oman,
Madagascar, etc. Since last year’s meeting we have known that members
ask for more practical articles on growing and keeping euphorbias. We
started to respond to it by a series of articles by our Chairman Rikus
van Veldhuisen. Further papers from members are welcome! Volker also
manages the website for the I.E.S. and after many years he would like
to pass on the maintenance of the website to someone else. He will keep
everything in good order until a suited replacement is found. It is
needless to say that managing the EW issues and the website is a lot of
work and Volker has always done a more than good job.
The
Curator of our Reference Collection, Jaap Keijzer, has been busy like
every year with propagating euphorbias so they become accessible to our
members.
One of
the
biggest projects not just for this year is organizing the International
Euphoria Convention at the Botanic Garden Meise in Belgium. Our
Publicity Officer Thomas Cammaerts, together with Rikus van Veldhuisen
and Jaap Keijzer, had a meeting with the Director of the BG Meise and
arrangements were made to organize a 2-day event with international
Guest Speakers, guided tours, a plant sale, a plant show and a view in
the Euphorbia Reference Collection of the BG Meise. We now have come up
with a rather impressive list of guest speakers, namely: Susan Carter,
Norbert Rebmann, Ricarda Riina, Petr Pavelka, Bob Potter and Rikus van
Veldhuisen. This Convention will be THE event for every Euphorbia
enthusiast. During this AGM Meeting the last problems concerning the
Convention were discussed and now everything can be posted online and
on the website. You can now find the registration form and all other
information on our website.
Another
channel to make good publicity is our Facebook page. We had a very
positive amount of new visitors to the page. The most popular
interaction is of visitors asking to identify their plants. New
pictures are posted regularly and the quality of the pictures is very
much appreciated by our I.E.S. members.
After
the brief reports it was time for members’ questions. After reading out
loud an e-mail of one of our members who had come up with a lot of good
suggestions, we needed to discuss these. One of his points was
reserving some space in the EW for members to interact with each other
and respond to the articles in EW. To us it was a good suggestion, but
we only publish 3 issues a year so the interaction in that column would
not be very user friendly and should better take place at our Facebook
page. Another point was not to make the articles too scientifical. The
most important suggestion was to put our EW issues online to decrease
the costs of printing and to allow us to lower the membership fee. We
will discuss this matter in future intern meetings.
Increasing
the number of subscribers is also a regular point of discussion. The
suggestion to put EW online and to charge lower membership rates will
be something to study in future. Some members join through Facebook and
other mostly through word-of-mouth recommendation.
Other
activities are somewhat on hold because of the organization of the
Convention. If this Convention becomes a success, we might be able to
pick up our plans to publish a book on Jatrophas, a last work of Albert
Pritchard.
With
this our
Chairman offered to talk about any other subjects. Former Chairman Alan
Butler wanted to compliment Rikus for a job well done and added that
our Committee is doing a great job. Thanks for those kind words Alan.
Our
Chairman then closed the meeting. We all hope to meet a lot of
Euphorbia enthusiasts at the Convention next year!
