Next orchid drive "Strasbourg Expo"
We are planning to go to the exhibition of Strasbourg in March.
We could possibly bring one or two orders of our members back to Paris...
The nurseries of this show are very interesting.
You can send your orders directly to them.
From March the 16th to 19th 2012.
The press documents: Press documents
To visit the exhibition: AROS (SFO)
Our participation to the exhibition "La Capelle"
Each year, the local Rotary Club made this beautiful exhibition.
We do our best. This year they are doing bigger, with
a chocolate show (with tasting) on the first floor.
A botanical judgment will be made by Mr. Rik Neyrinck and his judges students of Pachacamac.
Their website: Orchid show of La Capelle
Next meeting with the UIA
We are happy to see again on the 14/03/2012 at 3pm Mr. Paul Broc and his team at the Botanical Garden of Maisons Alfort,
in class A. of the Letard building. Our meeting will be dedicated to the culture and repotting
of the three following orchids: Phalaenopsis, Cymbidium and Miltoniopsis.
Getting there: Plan access
Donation to the site of Jay Phal

Website orchidspecies
Jay Phal is a true orchid lover: he spends a lot of time
updating his website. He has no state aid and no subsidies;
he do so as a personal passion and love for these plants.
Following the reclassification of botanical orchids, and given
the participatory nature of its site, it became very rich and
full, his work has increased dramatically. He has lots of
acquisitions costs of reference materials, as well as informatics.
We decided to contribute to his efforts because we know what it means to work hard and
we also know what it is to work without subsidies (we have never made the request).

Our article Oncidium Swartz 1800 by Mrs. MJ Freuler.
A full article with the new classification of Oncidium, accompanied by
beautiful pictures!
The type described by the botanist Olaf Swartz in 1800, referring to species that
Linnaeus had classified in Epidendrum. This genus is one of the largest in the
orchid family with many other allied genera.
Over the years, many species have been transferred to the genus Oncidium,
or otherwise have been discarded. All Oncidium alliance has undergone several
changes that have sometimes been accepted by the majority. Recently,
in agreement with studies on DNA and adopting the perspective of the grouping
of taxa, called "lumping" or the opposite of "splitting" (separation),
the scientific body has conducted a series of transfers in taxonomic of this genus.

According to Mark W. Chase, Norris H. Williams, Kurt M. Neubig and W. Mark Whitten
2008 (Taxonomic Transfers in Oncidiinae to Agreement with Orchidacearum Genera,
Vol. 5. Lindleyana 21 (3): 20-31), the genus that concerns us is composed of following synonyms:
- Odontoglossum Kunth
- Sigmatostalix Rchb. f.
- Cochlioda Lindl.
- Petalocentrum Schltr.
- Roezliella Schltr.
- Symphyglossum Schltr.
- Mexicoa Garay
- Miltonioides Brieger & Lückel
- Solenidiopsis Senghas
- Chamaeleorchis Senghas & Lückel
- Collare-stuartense Senghas & Bockemühl
- Heteroncidium Szlach., Mytnik & Romowicz

Given the so many kinds of this genus and transferred to the complexity of the enumeration of general
characteristics that results, we will detailed in the following lines, the aspects of those kind of Oncidium called
"classic" and one should refer to specific conditions when
the basionym we will deal with species of the genera recently included in the genus Oncidium.

Taxonomic notes:
Subspecies and form chilapensis of Laelia anceps - by Viateur Boutot
On December 2011 in the Pachacamac's Gazette (No. 18), a picture illustrating our
article "Endangered Species and habitats / In Mexico, included (in page 7)
the following legend:
"Laelia anceps subsp. anceps, sometimes referred as Cattleya chilapense and
Laelia anceps f. chilapensis" [see photo right]
The contributor who provided this photo, Steven Beckendorf, has notice us his
disagreement with the diagnosis of the recognized authority on nomenclature,
the World Checklist of Selected Plant Families (WCSPF) which has determinated that
the accepted name for Laelia ancepsf. chilapensis Soto Arenas1 was
Laelia anceps subsp. anceps.

On one hand, S. Beckendorf, Professor at the Department of Molecular Biology at the
University of California, recalls that WCSPF recognizes the existence of
two subspecies of Laelia anceps:
1) Laelia anceps subsp. anceps;
2) Laelia anceps subsp. dawsonii.
On the other hand, the scientist, based on a more recent publication than that
which refers the WCSPF says:
1) that the shape chilapensis is a variation of subspecies dawsonii;
2) that the petals of the form chilapensis include macules fuchsia.2
In short, S. Beckendorf said that the legend of the photo that he send us should
have been, in accordance with the choices and determinations
of the authors Halbinger, Soto et al. as indicated
1) Laelia anceps subsp. dawsonii
or
2) Laelia anceps subsp. dawsonii f. chilapensis in reference to flower color.
In conclusion, the shape chilapensis - whose name comes from Chilapa de
Álvarez in the Mexican state of Guerrero - cannot be a variant of Laelia anceps
subsp. anceps as suggested by the WCSPF.
The two subspecies of Laelia anceps are found in distinct geographical areas.
The distribution zone of the subspecies anceps is located in the Sierra Madre Oriental
and at the central highlands of Chiapas, in the basin of the Gulf of Mexico,
while the subspecies dawsonii was collected on the Pacific slope of the Sierra
Madre del Sur in the states of Oaxaca, Guerrero and Jalisco. ________

Sievekingia peruviana and its culture sheet.
Sievekingia peruviana Rolfe ex C. Schweinfurth 1943.
Reichenbach described the genus in 1871 in Beiträge zur systematischen Pflanzenkunde. The genus name
was given in honor of Dr. Sieveking, mayor of Hamburg, a friend of Reichenbach.
This pretty species is native to Peru. It is found especially in the state of Junin near the Rio Tulumayo,
in the Ayacucho region, and also in the state of Madre de Dios, at the east from Cusco going to Puerto Maldonado. It grows
in tropical rainforest around 1200 to 1500 meters.
A complete document in order to succeed your orchid culture on this fascinating orchid. We thank our anonymous
cultivator for divulging his secrets...
We also thank Mr. Günter Gerlach for his beautiful photos and his invaluable assistance.
