The genus Berthelotia DC. (presently a synonym of the accepted name Pluchea Cass.), Asteraceae, Inuleae has been regarded as comprising two species, B. lanceolata DC. and B. sericea (Nutt.) Rydb. It honors the French naturalist Sabin Berthelot (1794–1880) for his contribution to the studies of the flora and fauna of the Canary Islands. Under the le...

At the Montgomery Botanical Center (MBC), Miami, Florida, USA, a graduate course on Plant Taxonomy and Nomenclature, administered by the Florida International University (FIU)-Biology Department, was held April 25–29, 2022.

The name Webbia has been used to describe three different genera: Webbia Spach (Clusiaceae), Webbia DC., nom. illeg. (Asteraceae: Vernonieae), and Webbia Sch.Bip., nom. illeg. (Asteraceae: Astereae). The title of the botanical journal Webbia does not pertain to any of these generic names but is a mere Latinization of the surname Webb, and was creat...

An update of the nomenclature of 49 Caribbean Island‐occurring taxa of Plumeria (Apocynaceae: Plumerieae) is presented. We designate lectotypes for the following 29 names: Plumeria alba var. jacquiniana, P. apiculata, P. barahonensis, P. beatensis, P. berteroi, P. biglandulosa, P. confusa, P. cuneifolia, P. dictyophylla, P. discolor, P. domingensis...

Third and final volume of An Annotated Checklist of Indian Pteridophytes published by Mssrs. Bishen Singh Mahendra Pal Singh, Printers and Publishers, Dehradun, on 30.12.2020. It was a decade-long project on revision and cataloguing of Indian Pteridophytes (ferns and allies). The last such project attempted was Beddome's Handbook of ferns of 1883-1...

The new combination Psorothamnus arborescens (Torr. ex A. Gray) Barneby var. californicus (S. Watson) Sutherl., Gandhi, & Vincent is made here to accommodate Dalea californica S. Watson and Parosela californica (S. Watson) Vail var. simplicifolia Parish at varietal rank in Psorothamnus arborescens, necessitated by the priority of the varietal auton...

The new combination Dypsis lucubensis (Becc.) Kailash & Gandhi is made here to accommodate Chrysalidocarpus lucubensis Becc. and C. madagascariensis Becc. at species rank in Dypsis, necessitated by the later homonymy of D. madagascariensis (Becc.) Beentje & J. Dransf. (non; Woodrow).

A new subspecies and two new combinations are proposed in Onagraceae. Ludwigia glandulosa Walter subsp. brachycarpa C.-I Peng, subsp. nov . is morphologically distinct from the typical subspecies, with smaller capsules and leaves, different seed coat, and a restricted distribution. Epilobium sect. Pachydium (Fischer & C. A. Meyer) Hoch & K. Gandhi,...

Johann Reinhold Forster and his teenaged son John Georg Adam Forster (then 17) joined James Cook’s second voyage (1772-1775), as botanist and artist, respectively. Upon their return they described six species that are pertinent to the study of the Macaronesian flora. Previous typifications are revisited and we designate lectotypes for Aytonia rupes...

The Special Committee on Publications Using a Largely Mechanical Method of Selection of Types (Art. 10.5(b)) (especially under the American Code) was established at the XVIII International Botanical Congress (IBC) in Melbourne in 2011, with the mandate to develop a list of works that are deemed to have followed the American Code and any similar cas...

The typification and nomenclature pertaining to Funastrum heterophyllum (Engelm. ex Torr.) Standl. are reviewed. The legitimacy of several synonyms pertaining to this species is discussed. A revised and complete synonymy is provided.

This work is the first fully documented summary of Indian Ferns and Fern-Allies produced since the 19th Century Handbook of Ferns of British India etc. by Beddome in 1883. It is based on very detailed and exhaustive study of Indian collections in all relevant herbaria worldwide and on extensive fieldwork and collection in India and adjecent countri...

Recent systematic treatments for Jamaica have shown that the island is home to seven endemic genera of seed-plants [viz., Dendrocousinsia (Euphorbiaceae), Jacmaia (Asteraceae), Odontocline (Asteraceae), Portlandia (Rubiaceae), Salpixantha (Acanthaceae), Tetrasiphon (Celastraceae), and Zemisia (Asteraceae)]. These taxa account for over 23 species, w...

The Melbourne Congress of 2011 authorized a Special Committeeon Registration of Algal and Plant Names (including fossils), whichwas established the following year (Wilson in Taxon 61: 878–879.2012). Its explicit mandate was “to consider what would be involved inregistering algal and plant names (including fossils), using a procedureanalogous to tha...

The Special Committee on By-laws for the Nomenclature Section was established at the XVIII International Botanical Congress (IBC) in Melbourne in 2011, with the mandate to formalize the procedures by which changes to the Code are considered and voted upon by the Nomenclature Section, and to report to the XIX IBC in Shenzhen in 2017. With the wider...

The Special Committee on Registration of Algal and Plant Names (including fossils) was established at the XVIII International Botanical Congress (IBC) in Melbourne in 2011, its mandate being to consider what would be involved in registering algal and plant names (including fossils), using a procedure analogous to that for fungal names agreed upon i...

Pediomelum palmeri Grimes is validated, and P. ockendonii is rejected as a superfluous and illegitimate name.

Dates of publication are given for each novelty proposed in the New England Botanical Club’s journal Rhodora from volume 1, part 1, to volume 116, part 968. All of these issues are available online via the Biodiversity Heritage Library. Full bibliography data are provided for the 5775 validly published names of extant vascular plants proposed in th...

The Linnaean name Laurus borbonia was lectotypified in 1966 on a 1731 Mark Catesby etching. However, as the taxonomic identity of the lectotype is ambiguous, and might relate to either Persea borbonia or P. palustris (and may even have been drawn from two different genera of Lauraceae), an epitype is designated here to maintain application of the n...

Piptochaetium fuscum (Nees ex Steud.) Barkworth, Ciald., & Gandhi, a new combination replacing Piptochaetium setosum (Trin.) Arechav. Abstract A new name, Piptochaetium fuscum, is provided for a taxon hitherto known as Piptochaetium setosum (Trin.) Arechav. Morphological, anatomical, and molecular studies that argue against including Piptochae-tium...

Pycreus decumbens, described from Brazil, is noted as a synonym of the Old World species, Cyperus mundtii; a new name is provided for the eastern Brazilian Cyperus palustris; C. affinis is determined to be the correct name for Cyperus comosus (a relative of C. giganteus) and C. spicigerus is noted as an older name for C. schoenomorphus.

Generic delimitations and understanding of relationships among the herbaceous Afro-Asian genera Ammannia L., Hionanthera A. Fern. & Diniz, and Nesaea Comm. ex Kunth were long elusive due to the extensive similarity in their habit and floral morphology. Recently, studies based on morphological and molecularbased evidence found the three genera formi...

"Wolffia borealis" hitherto considered to have been validly published, was found to be not validly published and is validated here.

Rubus fockei was proposed in 1976 as a replacement name for R. fulvus, an illegitimate name published in 1910. Unfortunately, Rubus fockei had already been published in 1881, although not indexed until 1991, rendering R. fockei Gandhi illegitimate. Rubus kasthuriae is here proposed to replace R. fulvus.

We make generic transfers and rank changes of taxa distributed primarily in the southeastern United States. These include transfers from Prenanthes to Nabalus (Asteraceae or Compositae), from Senecio to Packera (Asteraceae or Compositae), from Onosmodlum to Lithospermum (Boraginaceae), from Trichomanes to Crepidomanes (Hymenophyllaceae), from Osman...

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...

080) Add the following sentence after the second sen-tence of Art. 9.10: "However, if it is established in the typifying publication (or in a prior publication), that all the cited specimens are in conflict with the description, and there is other original material that is not in conflict, then preference in choice of lectotype must be given to thi...

Rhododendron minus var. chapmanii (Alph. Wood) Gandhi & Zarucchi is validated here as a new combination.

Duthie, in his 1888 work, inadvertently published “Iseilema laxum Hack.” as a superfluous, illegitimate name for the 1856 name I. prostratum (L.)Anderss. The subsequent 1889 publication of I. laxum by Hackel, which excluded the type of I. prostratum, is, therefore, heterotypic, a later homonym, and illegitimate. A new name is here proposed for “Ise...

We review the nomenclatural and taxonomic history of eastern North American species traditionally treated in the genus Waldsteima Willd. (Rosaceae), and conclude that it is desirable to recognize three taxa (as has been done with rare exceptions) and to place these in the genus Geum L Given the equivocal morphological data and absence of molecular...

The validity of Cypripedium franchetti, as described by E. H. Wilson in 1912, and subsequent typification by P. Cribb in 1997 are discussed. We conclude that Wilson's description is valid, but that the material cited by Cribb was not part of the original material and, therefore, that his usage of the term holotype cannot be construed as an error fo...

Within the treatment of Solidago, Torrey and Gray (1842), there are no textual indicators of the ranks intended for subdivision of the genus, and all of the Torrey and Gray names for subdivisions of Solidago are rankless. The new combination Solidago sect. Ptarmicoidei is made.

Rupert Barneby (1964) expressed "doubts of the legality" in adopting "Astragalus tenellus Pursh" (1813) over A. multiflorus (Pursh) A. Gray (1864). His concern was justified since Pursh invalidated his own name when he simultaneously published Ervum multtflorum (the basionym of A. multiflorus) on a different page in the same work and cited "A. tene...

We support Kerguélen's (1977, 1987) assertion that both Lamarck (1798) and Willdenow (1809) independently published the identical name Panicum geniculatum and that P. Beauvois (1812) based his Setaria geniculata on Willdenow's name. The type collections of Lamarck's and Willdenow's names are different, but were from the same locality and belong to...

A reassessment of the taxonomy of Liatris borealis Nutt. ex J. McNab suggests that it is not conspecific with L. novae-angliae, but is a synonym of L. scariosa L. var. scariosa. Three varieties are recognized within the L. scariosa complex; the varietal name L. borealis var. novae-angliae, not hitherto validly published, is validly published here.
