The description of a new variety of Paphiopedilum villosum from Vietnam is published.
A new species of Paphiopedilum from Laos is described by André Schuitema, Sulivong Luang Aphay and Shunsuke Iio. It is called Paph. papilio-laoticus and belongs to the subgenus Paphiopedilum section Paphiopedilum.
A greenish white colour form of Paph. agusii Cavestro & Bougourd is described by Olaf Gruß, William Cavestro and Gus Benk as Paph. agusii f. alboviride.

The confusion surrounding the correct parentage of Phragmipedium ×grande/Grande continues as a new article is published by Franco Pupulin and Melissa Díaz-Morales in the scientific journal Phytotaxa.
"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).
Further more new names have been added, including the latest published hybrids (excluding the genus Paphiopedilum). The vast list of Paphiopedilum hybrids is still a work in progress.
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.
