# Melchior system

The Melchior system, "a reference in all taxonomic courses", is a classification system detailing the taxonomic system of the Angiospermae according to A. Engler's Syllabus der Pflanzenfamilien (1964), also known as "modified or updated" Engler system.
The collaborators in orders (and some families) were the following:
* Hans Melchior in Casuarinales, Juglandales, Balanopales, Leitneriales, Salicales, Fagales, Urticales, Didiereaceae, Piperales, Aristolochiales, Guttiferales, Sarraceniales, Papaverales, Hydrostachyales, Podostemonales, Julianiales, Violales, Cucurbitales, Myrtiflorae, Umbelliflorae, Primulales, Tubiflorae, Plantaginales, Liliiflorae p. p., Spathiflorae and Microspermae.
* G. Buchheim in Proteales, Cactales, Magnoliales and Ranunculales.
* W. Schultze-Motel in Santalales, Balanophorales, Medusandrales, Rhamnales, Malvales, Diapensiales, Ericales and Cyperales.
* Th. Eckardt in Polygonales, Centrospermae, Batales, Plumbaginales, Helobiae, Triuridales and Pandanales.
* G. K. Schultze-Menz in Rosales.
* H. Scholz in Geraniales, Rutales, Sapindales and Celastrales.
* G. Wagenitz in Thymelaeales, Ebenales, Oleales, Gentianales, Dipsacales and Campanulales.
* U. Hamann in Cyanastraceae, Pontederiaceae, Philydraceae, Juncales, Bromeliales and Commelinales.
