Melchior Treub (26 December 1851 – 3 October 1910) was a Dutch botanist. He worked at the Bogor Botanical Gardens in Buitenzorg on the island of Java, south of Batavia, Dutch East Indies, gaining renown for his work on tropical flora. He also founded the Bogor Agricultural Institute. He traveled and collected across many areas of Southeast Asia.
He was born in Voorschoten, and in 1873 he graduated in biology from the University of Leiden. Subsequently, he remained in Leiden as a botanical assistant. From 1880 to 1909 he was a botanist based in the Dutch East Indies.
In 1879 he was appointed a member of the Royal Dutch Academy of Sciences (KNAW) and was appointed as director of 's Lands Plantentuin in Buitenzorg (Bogor) in the year 1880. Treub worked on tropical flora on Java and organized the Botanical Garden as a world-renowned scientific institution of botany. Under his leadership many crucial researches were successfully completed on plant diseases of economic crops.
In 1903 he established the Buitenzorg Landbouw Hogeschool, a school that later evolved into the Bogor Agricultural Institute. In 1905 he became director of the newly established Department of Agriculture in the Dutch East Indies. In 1907 Treub was the recipient of the Linnean Medal for his outstanding achievements in sciences. The Dutch "Society for the Promotion of the Physical Exploration of the Dutch Colonies" is sometimes referred to as the Treub Maatschappij.
As a botanical collector, he traveled throughout the Indies, and to the Philippines, Sri Lanka, Singapore and Penang. He was interested in plant morphology and physiology, and published treatises on the morphology of Balanophoraceae, Loranthaceae and Lycopodiaceae. He is credited for coining the term "protocorm" to describe the early stages in the germination of lycopods.
He worked for nearly 30 years at the gardens before returning to the Netherlands in 1909 due to his worsening health. Dr. Treub then settled on the village of Saint-Raphael on French Riviera, where he died in 1910.
