Species phenology - the timing of key life events - is being altered by ongoing climate changes with yet underappreciated consequences for ecosystem stability. While flowering is generally occurring earlier, we know much less about other key processes such as the time of fruit ripening, largely due to the lack of comprehensive long-term datasets. Here we provide information on the exact date and site where seeds of 4,462 taxa were collected for the Index Seminum (seed exchange catalogue) of the Botanic Garden of the University of Coimbra, between 1926 and 2013. Seeds were collected from spontaneous and cultivated individuals across Portugal, including both native and introduced taxa. The database consists of 127,747 curated records with information on the species, or infraspecific taxa (including authority), and the day and site where seeds were collected. All records are georeferenced and provided with a confidence interval for the collection site. Taxonomy was first curated manually by in-house botanists and then harmonized according to the GBIF backbone taxonomy.
物种物候学——关键生命事件的时间安排——正在被持续的气候变化所改变，而这对生态系统稳定性的影响还未被充分认识。虽然开花通常会更早发生，但我们对其他关键过程（如果实成熟的时间）知之甚少，这主要是由于缺乏全面的长期数据集。在这里，我们提供了 1926 年至 2013 年间，在科英布拉大学植物园的 Index Seminum（种子交换目录）中收集的 4462 个分类群种子的确切日期和地点的信息。种子是从葡萄牙的自然和栽培个体中收集的，包括本地和引入的分类群。该数据库包含 127747 条经过整理的记录，其中包含有关物种或种下分类群（包括权威）以及种子采集日期和地点的信息。所有记录都经过地理参考，并为采集地点提供了置信区间。分类学最初由内部植物学家进行手工整理，然后根据 GBIF 骨干分类法进行协调。
