Data for: Have humans living within the Greater Cape Floristic Region been using the same plant species through time?

archaeological_data: A summary of all the botanical remains found within archaeological sites primarily within the Greater Cape Floristic Region (GCFR). Three sites, situated close to the GCFR were also included. The data information include: old botanical name, updated name of the plant species if it has changed (this was done in 2017), type of material that was found (e.g. charcoal sample), the age of the archaeological layer in which it was found (e.g. 15,000 BC) and what the authors thought it was used for. The range of material dates from 0 to 80 000 BC. It also includes the name of the archaeological site, what part of the GCFR it falls in, and the name of the study in which it was published. contemporary_data: A summary of all written accounts of plant species that are mentioned to have a specific use for humans. It covers the last 400 years to date. The information includes the old botanical name, the current botanical name (2017), the use category (e.g. medicinal or edible), the part of the plant that is used (e.g. leaves or roots), what it is used for (e.g. headaches or for making beer), how it is prepared (e.g. cooked in coals). It includes the reference source in which it was published and in what part of the GCFR it occurs.考古植物遗存数据集：该数据集汇总了主要采集自大开普植物区（Greater Cape Floristic Region, GCFR）内考古遗址的全部植物遗存，同时纳入3处毗邻该植物区的遗址。数据涵盖以下内容：植物物种的曾用学名、2017年更新后的现行学名、出土遗存的材质类型（如炭质样品）、其所在考古地层的年代（如公元前15000年），以及研究者推断的遗存用途。遗存的年代跨度为公元前0年至公元前80000年，此外还包含考古遗址名称、该遗址在大开普植物区内的所属分区，以及相关研究的发表信息。 当代植物利用数据集：该数据集汇总了近400年至今记载的所有被记录为对人类具有特定用途的植物物种相关文字资料。数据涵盖以下内容：植物物种的曾用学名、2017年更新后的现行学名、用途类别（如药用或食用）、所利用的植物部位（如叶片或根系）、具体用途（如缓解头痛或用于酿制啤酒）、制备方式（如炭火烹煮），以及资料的文献来源和该物种在大开普植物区内的分布区域。
