Silveira et al. (Phytotaxa 352 (1): 1–91; Phytotaxa 605 (1): 1–83 and Phytotaxa 640 (2): 125–160). Most of the specimens were collected by P. Silveira and collaborators, but some collections were offered. For example, these include specimens collected and cultivated by Olofron Plume, on the scope of her PhD at Cornell University, and by HAL (Martin-Luther-Universität Halle-Wittenberg herbarium).

It is will made available on GBIF (https://www.gbif.org/) so that it can be consulted by any interested researcher, and includes eight (8) type specimens. The collection whose data is published in this dataset was partly funded by the Portuguese Foundation for Science and Technology and UNESCO Fund for financing the work of A.Gonçalves with the scholarship SFRH/BD/51464/2011 and by the University of Aveiro and CESAM (UID/AMB/50017 - POCI-01-0145-FEDER-007638), to FCT/MCTES through national funds (PIDDAC), and the co-funding by the FEDER, within the PT2020 Partnership Agreement and Compete 2020, also (UIDP/50017/2020+UIDB/50017/2020) through national funds.

+351234370781 psilveira@ua.pt https://www.cesam-la.pt/psilveira 0000-0002-9253-5381 The collection was databased in BRAHMS 7.6 (Oxford University, UK), either directly from the field books (team's collections) or from original specimens' labels/documentation (other collector's specimens offered to AVE). Taxonomy fields, including authorship names, were checked against IPNI (https://www.ipni.org/) and POWO (https://powo.science.kew.org/). Standardization and checking of consistency was done with the tools available in BRAHMS 7.6. A selection of specimens, at least one for each taxon, several for more common and morphological diverse taxa, were imaged using a digital camera Canon 100D, installed inside a Godox DF-01 Light cube 80x80x80cm and connected to a PC running digiCamControl 2.1.6.0 (2018 Duka István). Contrast and light were adjusted using Paint.NET 5.1.12 (dotPDN LLC), and stored in JPG format at https://archive.org/. This data covers only a small part of the AVE collection, dedicated to the genus Calendula L. Geographically, it encompasses specimens from Spain (185), Portugal (84), Morocco (77) Italy (23, all from Sicily), Lebanon (17), Algeria (14), Tunisia (6), Israel/Palestine (2), and Greece (1). The temporal boundaries goes from 1966-1981's collections from German botanists, offered by HAL to AVE, to 2022's collections made on the scope of the expeditions to the Canary Islands made by P. Silveira's team (I. Simão and J.A. Reyes-Betancort. Sampling of the specimens was done following the usual methods described for their collection, preparation and mounting (Pinho et al. 2016) Consistency and standardization of the geography, people's names, taxonomy, dates, etc., was reviewed using BRAHMS 7.6 (Oxford University, UK). Coordinate uncertainty of the specimens that did not include precise coordinates of the collection site was estimated using Geopick (https://geopick.gbif.org). Paulo C. da Silveira 0000-0002-9253-5381 principalInvestigator The aims of this project were to: - mount the specimens of Calendula collected under the scope of the recently published taxonomical revisions of Calendula, including 8 type specimens; - make their data, and a selection of images, including the type specimens, available online on GBIF, therefore promoting universal access to this information; - train young alumni in the study of flora and herbarium management. IAPT 2025 “Small Collections Grant” Mostly Iberian Peninsula, Macaronesia and the understudied North of Africa (Morocco, Algeria and Tunisia) Two students were hired to process the Calendula backlog, i.e.: mounting in cardboard, including labels and using appropriate gummed archival linen tape. Type specimens were wrapped in their appropriate red banded sheets, while all the other specimens were enclosed in vegetal paper, and genus folders. This renders these collections ready to be consulted by any researcher upon request. Furthermore, their data, which has already been databased, will be made available on GBIF (https://www.gbif.org/) along with, at least, a selection of images, which will include eight (8) type specimens. 2026-03-26T00:51:14.027+00:00 dataset C. da Silveira P (2026).
