Découverte de Cypripedium calceolus (Orchidaceae) au Djurdjura (Algérie), nouvelle pour l’Afrique du Nord

Abstract

online. 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.

Combining current knowledge of Cypripedium calceolus with a new analysis of genetic variation in Italian populations to provide guidelines for conservation actions

“…These populations have recently been among the targets of the Floranet Life Project, which has implemented several conservation actions (Di Martino, Conti, Bartolucci, Ciaschetti, & Di Cecco, 2016;Box 2). As the Apennine populations of C. calceolus are the southernmost in Europe (but note that a disjunct population was recently discovered in Algeria; Nemer, Rebbas, & Krouchi, 2019), they may be considered vulnerable "edge populations" (but see García et al, 2010). This hypothesis is supported by the recent findings of elevation range shift towards higher elevations for C. calceolus in the Alpine range (Geppert et al, 2020;Perazza & Chini, 2020).…”

Phylogenomic Analysis of Target Enrichment and Transcriptome Data Uncovers Rapid Radiation and Extensive Hybridization in Slipper Orchid GenusCypripediumL

“…The taxon distributions were based on Eccarius (2009), Frosch and Cribb (2012), SC Chen et al . (2013), and Walid et al . (2019).…”

“…S1). The Mediterranean and Scandinavian regions were grouped with Western and Central Europe (area F) because only C. calceolus occurs in all three areas (Eccarius, 2009; Frosch and Cribb, 2012; SC Chen et al ., 2013; Walid et al ., 2019). We split area F from Eastern Europe and Russia (area G) at the boundaries of the Sarmatic and Pontic-South Siberian floristic provinces according to Schroeder (1998), as they have a more continental climate and match the limit of C. guttatum’s distribution in the European continent (Pfadenhauer and Klötzli, 2020; Supplementary Data Fig.…”

Découverte d’Epipactis microphylla (Orchidaceae) au Djebel Babor (nord-est de l’Algérie), orchidée nouvelle pour l’Afrique du Nord

“…2020). Grâce à cela, des découvertes ou des redécouvertes remarquables sont encore possibles, comme celles de Ophrys pallida (Hadji & Rebbas 2013), Neottia nidus-avis (Madoui 2019) et Cypripedium calceolus (Nemer & al. 2019).…”
