Rediscovery of two species of Croton (Euphorbiaceae) from littoral habitats of eastern Madagascar / Kent Kainulainen in Candollea, vol. 72, fasc. 1 (Année 2017)
[article]
Titre : Rediscovery of two species of Croton (Euphorbiaceae) from littoral habitats of eastern Madagascar Type de document : Livre Auteurs : Kent Kainulainen, Auteur ; Paul E. Berry, Auteur ; Benjamin Van Ee, Auteur Année de publication : 2017 Article en page(s) : pp. 35-44 Langues : Anglais Mots-clés : Euphorbiaceae Croton forêt littorale Résumé : "Two species of Croton L. (Euphorbiaceae) previously reported only from their type specimens, Croton chapelieri Baill. and Croton vatomandrensis Leandri, are reevaluated here and found to be geographically widespread along the eastern coastline of Madagascar. We provide updated descriptions, lists of selected additional specimens, distribution maps, and photographs of both species. We also designate an epitype for Croton chapelieri and a lectotype for Croton vatomandrensis. Croton chapelieri was the source of considerable taxonomic confusion, and we treat as synonyms here for the first time Croton aymoninorum Leandri, Croton louvelii Leandri, Croton daphniphylloides Radcl.-Sm., Croton daphniphyllum Radcl.-Sm., Croton daphniphyllum var. hirsutus Radcl.-Sm., and Croton rhododendroides Radcl-Sm. Croton chapelieri var. longepetiolata Radcl-Sm. is considered to be a synonym of Croton submetallicus Baill. With our improved understanding of the geographical ranges of Croton chapelieri and Croton vatomandrensis, we provide IUCN Red List conservation assessments for both species."

Titre : A revision of the Adenophorus Group and other glandular-leaved species of Croton (Euphorbiaceae) from northern Madagascar and Mayotte, including three new species Type de document : Livre Auteurs : Kent Kainulainen, Auteur ; Benjamin Van Ee, Auteur ; hanta Razafindraibe, Auteur ; Paul E. Berry, Auteur Année de publication : 2017 Article en page(s) : pp. 371-402 Langues : Anglais Mots-clés : Euphorbiaceae Croton Mayotte Résumé : "This paper provides a revision of the species of Croton L. (Euphorbiaceae)from northern Madagascar (mainly Antsiranana and northern Mahajanga Provinces) and Mayotte in the Comoros Archipelago that bear glands on the undersides of the leaves. This includes members of the Adenophorus Group as well as two species that do not belong to that group, namely Croton nudatus Baill. and Croton stanneus Baill. Croton nudatus has been a problematic name since its publication due to the leafless state of its type. We were able to match the type with material recently collected near the type locality, and we provide an amended description for this species. Croton stanneus is another previously poorly understood species, which is actually one of the most widespread species of Croton in Madagascar. We also re-evaluate species delimitations in members of the Adenophorus Group from northern Madagascar and Mayotte, and we describe three new species, Croton mayottae P.E. Berry & Kainul., Croton orangeae Kainul. & P.E. Berry, and Croton sahafariensis Kainul. & P.E. Berry. Croton loucoubensis Baill. is resurrected from synonymy, and nine other species names and eight varieties are reduced to synonymy under Croton adenophorus Baill., Croton loucoubensis, Croton nudatus, Croton scoriarum Leandri, Croton stanneus, or Croton tsiampiensis Leandri. Full descriptions are provided for these species as well as for Croton bathianus Leandri, another misunderstood species in the group. A key to the seven species of the Adenophorus Group and the two look-alikes from northern Madagascar and Mayotte is provided. An epitype is designated for Croton nudatus, and lectotypes are designated for Croton adenophorus, Croton bathianus, Croton loucoubensis, Croton scoriarum, Croton stanneus, and Croton tsiampiensis."
