The Australian plant collections of diels and pritzel 1900–1902

Ludwig Diels and Ernst Pritzel undertook a two year collecting trip between 1900–1902 that included Western Australia, the eastern seaboard and New Zealand. Material collected on this expedition resulted in publication of over 300 new taxa. The loss of many of Diels’ types during a bombing raid on Berlin in 1943 has resulted in a need to designate neotypes for many of these names. The history and possible nomenclatural significance of the joint collections they donated to the Western Australian Museum in 1901 is examined to assist identification of candidate material.
