For centuries, a quiet corner of the Natural History Museum has concealed a secret: a previously undocumented historical seed collection. Hidden in locked cabinets, hundreds of small paper packets hold botanical specimens—and unanswered questions. This article offers a glimpse into this overlooked collection, the detective work behind its investigation, and the exciting possibilities that still lie ahead. The mystery remains unsolved—for now.
A Vast Botanical Treasure
The Natural History Museum’s botany collection contains more than five million specimens gathered worldwide over 300 years. These range from herbarium sheets and carpological (fruit) collections to microscopic slides, wet specimens, and seeds (Fig. 1). Ideally, each specimen carries detailed scientific and historical information, allowing researchers to reconstruct past ecosystems, track species distributions, and study evolutionary and climate-related change over time.
Equally important is the historical context: who collected the specimen, under what circumstances, and how it entered the Museum. Such information brings collections to life, revealing the people, motivations, and networks behind scientific discovery. Yet many specimens lack this documentation. Among them are seed packets stored quietly in locked cabinets of the herbarium.
