Orchid Digest Volume 84(4): (2020)
Special Year-end Issue - The Phragmipedium Issue
Frank Cervera :
“This special edition of the Orchid Digest contains the most accurate and concise treatise on the genus Phragmipedium available today. Unlike other books on the
genus, the checklist of species is based on population dynamics and the realities of the natural world, and is supported by twenty-five (25) years of hands on field research. This spectacular edition contains many in situ
photographs supporting the taxonomic treatment and teaches Phragmipedium culture from the viewpoint of natural populations, and correctly asks, and answers, what Mother Nature can teach
us about this beautiful and poorly understood genus. This special edition also includes a treatise on the species concept within the genus that explains why the genus is plagued by an excessive number of synonyms.”
The articles in this issue of Orchid Digest are :
- An Introduction to the Phragmipedium Checklist by Harold Koopowitz.
- A Checklist of Phragmipedium Species by Frank Cervera.
- Phragmipediums: What Can Mother Nature Teach Us about Growing our Phragmipediums? by Frank Cervera.
- Phragmipedium Taxonomy and The Species Concept: Who Is Correct, Mother Nature or Us? by Frank Cervera.
- Book Review: Vanishing Beauty Native Costa Rican Orchids, Vol. 2: Lacaena – Pteroglossa by Phillip Cribb.
- Breeding for White Phragmipedium Hybrids by William Goldner.

Paphiopedilum Südostasiatische Frauenschuhe by Olaf Gruß
On his Facebook page Olaf Gruß announced 28-Sep-2020 the upcoming publication of the first volume of a three part series in German on the genus
Paphiopedilum.
This first volume (Band 1) is dealing with Brachypetalum, Parvisepalum, Emersonianum, all multifloral and sequential flowering species, and includes lists of
hybrids. The book is in DIN A4 hardcover format and has over 530 pages and well over 2000 colour illustrations and photos.
It is published in November 2020. The price of the book is €120 (€100 if you are a subscriber to the OrchideenZauber magazine) and can be ordered directly from the author (a-o.gruss@t-online.de)
or from the publisher Orchideenzauber-Verlag (Dr. J. Schmidt / djs@orchideenzauber.eu).
The second volume (Band 2) will contain the remaining species. And the third volume (Band 3) will be about the hybrids, including all natural hybrids, many primary hybrids and an overview of
further breeding.
October 2019 a new book by Olaf Gruß was published as OrchideenZauber special edition (Sonderausgabe 10). This 135 page book in German contains over 300 photos
and shows Olaf's latest views on the genera Phragmipedium, Mexipedium and
Selenipedium.
The price for this book is €29 and is available directly from the author (a-o.gruss@t-online.de) or can be ordered from the publisher Orchideenzauber-Verlag
(Dr. J. Schmidt / djs@orchideenzauber.eu).
On 06-May-2020 in the journal Richardiana an
article
was published in which Aurélien Sambin and Guy Chiron announce the discovery of several new populations of
Selenipedium. These turned out to be different to al known species at the time. This new taxon is described as
Selenipedium aucourdianum.
In the same article the taxonomic place of Selenipedium/Apedium chironianum is discussed.
Abstract of the article:
“Several Selenipedium populations have been found in the Sinnamary, Kourou and Regina regions, east and southeast of the French Guiana. A thorough study showed
that these plants are very different from all other known species, especially by the remarkable size of its flowers. They are described as a new species, illustrated
and compared with S. isabelianum, S. palmifolium and S. steyermarkii. A map of geographical distribution as wel as a key to all the species of the
genus are proposed. Taxonomic notes on Selenipedium palmifolium and Apedium chironianum are added.”
In an article
that was published 11-Nov-2019 in the journal Phytotaxa, a new species of Phragmipedium from Peru is described
by Alexander Damián Parizava, Melissa Díaz-Morales and Franco Pupulin.
Abstract of the article:
“A new species of Phragmipedium section Lorifolia, P. cabrejosii, is described and illustrated from Peru, and its affinities are discussed. It is mainly
compared with P. caricinum, from which it is distinguished by the simple inflorescence, the elliptic dorsal sepal, that is apically white, the shorter, apically twisted
pale yellow petals tinged with rose, and the ovate-subrhombic staminodial shield (vs. reniform).”
28-Oct-2019 an article
was published in the annual journal Flora Mediterranea by the Foundation pro Herbario Mediterraneo on behalf of OPTIMA. In this Italian peer-reviewed
journal the announcement was made that the orchid species Cypripedium calceolus Linnaeus was discovered in the DjurDjura National Parc in Algeria,
North Africa.
Abstract of the article:
“Discovery of Cypripedium calceolus (Orchidaceae) in Djurdjura (Algeria), news for North Africa. — Cypripedium calceolus L. (Orchidaceae) native to
Eurasia is considered one of the flagship plant species of nature conservation. Because of its wide range, this species could be considered a taxon of minor concern, near
threatened, vulnerable, endangered or critically endangered.
This orchid was discovered in the Djurdjura, in north-central Algeria. Ecological notes are also provided. This is the first report of this species in North Africa. This discovery
will enrich the Algerian orchid in general and that of Kabylia in particular.”
After re-evaluation of the morphological characteristics, geographical distribution and study of molecular data, Yung-I Lee,
Pei-Chun Laio and Tsan-Piao Lin conclude that the most reasonable taxonomic treatment is to separate Taiwan's
population of Cypripedium macranthos as an independent entity. 05-Aug-2019 they describe this population as
Cypripedium taiwanalpinum in an
article
in Taiwania.
Abstract of the article:
“This report presents one new hybrid orchid of Taiwan, i.e., Gastrochilus × hsuehshanensis which resulted from hybridization between G. formosanus and
G. rantabunensis. Also, the existence of both Cyrtosia javanica and Cypripedium macranthos in Taiwan is questionable, and these were excluded from the
Taiwanese orchid flora.”
The confusion surrounding the correct parentage of Phragmipedium ×grande/Grande
continues as a new article
by Franco Pupulin and Melissa Díaz-Morales is published on 11-Dec-2018 in the scientific journal
Phytotaxa.
Abstract of the article:
“The taxonomic history of Phragmipedium × grande is traced to show that its current treatment as the cross between P. longifolium
and P. humboldtii is untenable. According to our interpretation of the holotype and other materials prepared from specimens of the original
cross, the name Phragmipedium × grande, as well as its counterpart, the orchid grex Phragmipedium Grande, have to be treated
as the cross between P. longifolium and a species of sect. Phragmipedium from South America. The similarity of the flowers obtained
crossing P. longifolium with P. caudatum and with P. warszewiczianum prevents, at this stage, a definitive statement about the
original parentage of P. × grande, so it is advisable to treat it as the hybridizer originally stated, a cross of P. longifolium
with the pollen of P. caudatum. This nothospecies cannot be formed under natural conditions, as the geographic ranges of the parental
species do not overlap. The natural hybrid between Phragmipedium longifolium and P. humboldtii, previously reported from Panama and
recorded here for the first time from Costa Rica, is described as P. × talamancanum. Full illustrations of the new nothospecies are
provided.”
