Are you looking for the old PhragWeb website? Use the link in the top right corner of
the screen to go there. This Slipperiana website is still very much a work in progress.
Welcome (back).
Again new names have been added. The latest hybrid registrations are added to the website. The vast list of Paphiopedilum
hybrids is still a work in progress. Also the programming behind the website has been further extended. For example the scripts and webpages are now ready for
Cultivar Groups to be included in the lists. So from now on those entities will be added to the website as well.
More recently for every hybrid there is now an ancestry tree displayed on the data page.
Interesting articles.
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."
