Curating an online checklist for Erica L. (Ericaceae): contributing to and supporting global conservation through the World Flora Online.

To support the work of the Global Conservation Consortium for Erica and update the Erica checklist in the World Flora Online (WFO), we have curated the taxonomic backbone in the WFO by expanding it to include updated nomenclatural information from the International Plant Name Index, missing names present in the World Checklist of Vascular Plants (WCVP), the Botanical Database of Southern Africa (BODATSA), and from the "International register of heather names" database, a data source not readily available online. The result is the most robust database of Erica names to date, including 851 species, 111 subspecies, 244 varieties, and 2787 synonyms, which is a reliable reference for initiatives such as the Erica identification aid, conservation prioritisation, and gap analyses. We disambiguate common orthographic variants within the database and present an overview of these. We also comment on the correct orthography of E.heleophila Guthrie & Bolus and E.michellensis Dulfer and the validity of E.tegetiformis E.G.H.Oliv. are discussed, and the use of E.adunca Benth. for a South African species rather than E.triceps Link, which is here regarded as insufficiently known and of uncertain application, is clarified.

Erica L. (Ericaceae): homonyms amongst published names for African species and proposed replacement names.

In support of ongoing taxonomic work on the large and complex flowering plant genus Erica (Ericaceae), we document nineteen pairs of homonyms representing currently used illegitimate names. We provide replacements for thirteen names and new typifications for five. We relegate five names to synonymy: Ericaaemula Guthrie & Bolus under Ericadistorta Bartl.; Ericaarmata Klotzsch ex Benth. under Ericaumbrosa H. A. Baker; Ericacapensis T.M. Salter under Ericaturbiniflora Salisb.; Ericalanata Andrews under Ericaflaccida Link; and Ericatomentosa Salisb. under Ericavelutina Bartl. Finally, we suggest conservation of Ericaaristata Andrews. The new names are: Ericaadelopetala E.C. Nelson & E.G.H. Oliv. replacing Ericainsignis E.G.H. Oliv.; Ericabombycina E.C. Nelson & Pirie replacing Ericaniveniana E.G.H. Oliv.; Ericaconcordia E.C. Nelson & E.G.H. Oliv. replacing Ericaconstantia Nois. ex Benth.; Ericadidymocarpa E.C. Nelson & E.G.H. Oliv. replacing Ericarugata E.G.H. Oliv.; Ericagalantha E.C. Nelson & E.G.H. Oliv. replacing Ericaperlata Benth.; Ericamallotocalyx E.C. Nelson & E.G.H. Oliv. replacing Ericaflocciflora Benth.; Ericanotoporina E.C. Nelson & E.G.H. Oliv. replacing E.autumnalis L.Bolus; Ericaoliveranthus E.C. Nelson & Pirie replacing Ericatenuis Salisb.; Ericaoraria E.C. Nelson & E.G.H. Oliv. replacing Ericaspectabilis Klotzsch ex Benth.; Ericaoresbia E.C. Nelson & E.G.H. Oliv. replacing Ericademissa Klotzsch ex Benth.; Ericapoculiflora E.C. Nelson & E.G.H. Oliv. replacing Ericastenantha Klotzsch ex Benth.; Ericarhodella E.C. Nelson & E.G.H. Oliv. replacing Ericarhodantha Guthrie & Bolus; Ericasupranubia E.C. Nelson & Pirie replacing Ericapraecox Klotzsch.

Archibald Menzies on Albemarle Island, Galápagos archipelago, 7 February 1795.

Menzies made the earliest extant botanical collections in the Galápagos; five sheets, representing three endemic species, are known. Menzies's own account of the visit is also extant and is transcribed here from his manuscript journal.

Daniel Chambers Macreight FRCP, FLS (1799-1856), a little-known, innovative Irish botanist.

Biographical information is provided for Daniel Chambers Macreight. He worked in Augustin-Pyramus de Candolle's herbarium at Geneva during the early 1830s, and later in the decade was prominent in medico-botanical circles in London. Macreight retired in 1840, due to ill-health, and moved to Jersey in the Channel Islands where he died. In 1837, he published an innovative "Manual of the British flora" which covered both native and cultivated plants. This flora contained two novel features: dichotomous keys were provided to assist students to identify plants, and the category subspecies was employed for taxa within the genera "Rosa," "Rubus" and "Salix."
