Johannes Paulus Lotsy (11 April 1867 – 17 November 1931) was a Dutch botanist, specializing in evolution and heredity. Lotsy was born in Dordrecht and died in Voorburg.
Career[]
After getting his PhD from Göttingen University he had a teaching positions at Johns Hopkins University (1891-1895) where he was director of the herbarium. From 1896 to 1900 he worked in Java. Then he taught at Leiden University (1904-1909), as a lecturer in Systematic Botany. He became director of the State Herbarium (Rijksherbarium) 1906–1909, then Secretary of the Hollandsche Maatschappij van Wetenschappen.
He founded the Association internationale des Botanistes and was editor of the Botanisches Centralblatt. He proposed a system of plant classification, based on phylogenetics. Lotsy argued for a major role of hybridization in evolution.[1][2]
Expeditions[]
India (1895-1900), the United States (1922), Australia and New Zealand (1925), South Africa (1926-27), and Egypt (1930). He also studied the flora of Italy and Switzerland.

System[]
Lotsy argued that the monocotyledons were diphyletic, with the Spadiciflorae being derived from the dicotyledons (specifically Piperales) and the remainder from a hypothetical ancestor, the Proranales. Hutchinson, who argued for a monophyletic origin, considered this improbable.[3]
