Interesting articles.

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."
