This dataset represents over three thousand seed plants fluid collection at the Natural History Museum that have been recently recurated with 70% IMS (Industrial methylated spirit). The collections are arranged as per jar size rather than taxonomically in order to maximise space. The collection ranges from early 19th century to the current era and it continues to grow with material incorporated with recent acquisitions. Over 150 families are represented with some important type specimens such as the world's largest flower-Rafflesia arnoldii R.Br collected by Raffles and Arnold. Other notable collections include several types of orchids collected by C.E. Carr from New Guinea during the second world war and John Gossweiler from Angola. The largest collection is from Nancy Garwood (over 700 bottles) which consists of some carpological material collected from Panama as well as seedlings. Several collections have corresponding herbarium sheets in the General Herbarium. By curating these collections, we have now made these collections accessible. We hope that more people interested in these collections will be able to make use of these collections for their research and help us to update the collections by way of adding determinations. The data will be eventually ingested in KE-Emu, the Museum's database in due course.
