Kainulainen, K., B. Van Ee, H. Razafindraibe & P.E. Berry (2017). A revision of the Adenophorus Group and other glandular-leaved species of Croton (Euphorbiaceae) from northern Madagascar and Mayotte, including three new species. Candollea 72: 371–402. In English, English abstract. DOI: http://dx.doi.org/10.15553/c2017v722a15 This paper provides a...

All published names of Croton from Madagascar, the Comoros, and the Mascarenes are treated here. We indicate which names are currently accepted (123 native species and 1 introduced), which ones we consider to be heterotypic synonyms (188), which ones are doubtful (25), and which ones should be excluded (5). We newly designate lectotypes for 108 nam...

Kainulainen, K., P.E. Berry & B. Van Ee (2017). Rediscovery of two species of Croton (Euphorbiaceae) from littoral habitats of eastern Madagascar. Candollea 72: 35–44. In English, English and French abstracts. Two species of Croton L. (Euphorbiaceae) previously reported only from their type specimens, Croton chapelieri Baill. and Croton vatomandren...

Background and aims: Wood is a major innovation of land plants, and is usually a central component of the body plan for two major plant habits: shrubs and trees. Wood anatomical syndromes vary between shrubs and trees, but no prior work has explicitly evaluated the contingent evolution of wood anatomical diversity in the context of these plant hab...

Berry, P.E., B. Van Ee, K. Kainulainen & H. Razafindraibe (2016). Croton aleuritoides P.E. Berry (Euphorbiaceae), a distinctive new tree species from Montagne des Français in northern Madagascar. Candollea 71: 181–188. In English, English and French abstracts. Croton aleuritoides P.E. Berry (Euphorbiaceae) is described from deciduous forests on tsi...

Six species of Croton from the Moramanga District of the Alaotra-Mangoro Region of eastern Madagascar (Toamasina Prov.) are newly described here, five of which occur in the Ambatovy mining concession. A seventh new species is described from the Ankerana Forest in the Atsinanana Region, some 80 km to the northeast of the town of Moramanga, which is...

Croton cupreolepis (Euphorbiaceae) is newly described from montane, evergreen forests of eastern Madagascar. It is distinguished by its coppery-lepidote trichomes that form a dense covering on the floral buds and inflorescences, as well as on the dorsal side of the petals of both pistillate and staminate flowers, and also by its distinctive recurve...

A molecular phylogeny, morphological descriptions, species lists and a key to the sections of Croton L. (Euphorbiaceae) recognised for Australia are presented. The molecular phylogenetic results supported the recognition of six sections, to account for the 29 native Australian species. The monophyly of each of these sections was highly supported in...

Euphorbia is among the largest genera of angiosperms, with about 2000 species that are renowned for their remarkably diverse growth forms. To clarify phylogenetic relationships in the genus, we used maximum likelihood, bayesian, and parsimony analyses of DNA sequence data from 10 markers representing all three plant genomes, averaging more than 16k...

The application of the names Croton glabellus, C. lucidus, and Phyllanthus glabellus has been confusing since the earliest publications that used them. After a thorough review of these publications and corresponding herbarium specimens, we clarify the nomenclatural confusion surrounding these names and their taxonomy. We identify a new name, Phylla...

Phylogenetic relationships of Croton section Cleodora (Klotzsch) Baill. were evaluated using the nuclear ribosomal ITS and the chloroplast trnL-F and trnH-psbA regions. Our results show a strongly supported clade containing most previously recognized section Cleodora species, plus some other species morphologically similar to them. Two morphologica...

The contribution of J. F. Klotzsch to Croton taxonomy is summarised through a review of the original literature, an examination of specimens and taxonomic decisions. The currently accepted names are given for Klotzsch's taxa associated with Croton. The new combinations Astraea comosa and A. jatropha are made. Lectotypes are designated for C. comosu...

Croton (Euphorbiaceae) is a large and diverse group of plants that is most species-rich in the tropics. We update the infrageneric classification of the New World species of Croton with new evidence from phylogenetic analyses of DNA sequence data from all three genomes. The relationships of species that were previously placed in conflicting positio...

PREMISE: Bromeliaceae form a large, ecologically diverse family of angiosperms native to the New World. We use a bromeliad phylogeny based on eight plastid regions to analyze relationships within the family, test a new, eight-subfamily classification, infer the chronology of bromeliad evolution and invasion of different regions, and provide the bas...

section is described, with a disjunct distribution in Mexico and South America. It is recovered sister to section in Bayesian, Maximum Likelihood, and Maximum Parsimony analyses of nuclear ITS and chloroplast DNA sequence data. Two new subsections, subsection and subsection , are recognized within section . These well-supported sister clades includ...

Croton ha sido lectotipificado por varios autores con dos diferentes especies, C. aromaticus y C. tiglium. Discutimos porqué C. tiglium tiene prioridad. Sección Cascarilla ha sido aceptado por mucho tiempo como el nombre de la sección más grande de Croton, pero reconociendo que su especie tipo, C. cascarilla, es un sinónimo de C. eluteria, la espec...

Most of the arborescent Croton species in the New World were treated by Webster as belonging either to C. sect. Cyclostigma Griseb. or C. sect. Luntia (Neck. ex Raf.) G.L. Webster. The circumscription of C. sect. Cyclostigma has been treated recently. In this paper we focus on C. sect. Luntia, which was subdivided by Webster into two subsections, C...
