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.
The confusion surrounding the correct parentage of Phragmipedium ×grande/Grande
continues as a new article is published (11-Dec-2018) by Franco Pupulin and Melissa Díaz-Morales
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."
The article can be found on the website of Phytotaxa (www.mapress.com/j/pt)
and I also found the article on the page of Franco Pupulin on the ResearchGate website
(www.researchgate.net/profile/Franco_Pupulin).
Species' influence charts.
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.
