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.

 


 

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."

 


 

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."

Species' influence charts.

Species' influence chart example.
With the revision of this website that was uploaded on 08-Feb-2018 came a new feature. On the Ancestry tab of the data page of every hybrid, a pie chart has been added that shows the percentage of influence of the species involved in the creation of the hybrid.
