Nomenclatural notes on Brazilian Celtis (Cannabaceae)

Abstract

In preparation for a new Neotropical taxonomic review and a global phylogeny focusing on the Neotropical lineages of Celtis, some nomenclatural changes are needed. Lectotypes are designated for Celtis alnifolia, C. asperula, C. brasiliensis, C. clausseniana, C. diffusa, C. morifolia, C. fluminensis, C. glycycarpa, C. hilariana, C. membranacea, C. orthacanthos, C. selloviana and Momisia integrifolia, and an epitype is designated for Celtis asperula. Celtis flavovenarum was proposed as a new name to replace the homonym C. morifolia. For C. spinosa we provide the locality of its type.

Phylogenomic analysis of the hemp family (Cannabaceae) reveals deep cyto‐nuclear discordance and provides new insights into generic relationships

“…Celtis gomphophylla , in particular, is usually a dioecious deciduous tree with unarmed branch and nearly entire leaf margin, persistent sepals, two styles (with unlobed stigma) on the mature fruit (as shown by the following specimen: https://science.mnhn.fr; herbarium collection number: P00562034) and brown endocarps, with distribution in tropical and southern Africa, Comoros, and Madagascar (Rendle, 1916; Leroy, 1952; Polhill, 1966; Sattarian, 2006; https://powo.science.kew.org/taxon/urn:lsid:ipni.org:names:851066-1). Celtis schippii occurs in the Neotropics (specifically, central and western South America) but differs from other Celtis species in the region in having unarmed branches, persistent sepals on the mature fruit, and membranaceous and black endocarps (Berg & Dahlberg, 2001; Zamengo, 2019; Zamengo et al, 2020). In 1978, Argentinian scientists documented the remarkable morphological differences between the embryos of C. schippii and those of other extant species and genera of Cannabaceae and Ulmaceae, prompting them to name a new genus, Sparrea Hunziker & Dottori, for this unique species (Hunziker & Dottori, 1978).…”

A revision of the Celtis iguanaea complex (Cannabaceae) and the reinstatement of an additional species from southern South America

“…) has undertaken a new revision of the nomenclature and taxonomy of the Neotropical species of Celtis to update the circumscription of the genus. At present, some results have been published (Chamorro et al 2021, Chamorro 2022, Zamengo et al 2023a, but further research is still needed. This includes the current contribution with a revision of the C. iguanaea complex.…”
