### Author
Sonder, Otto Wilhelm (1812-1881), German (Holstein) botanist and pharmacist; pharmaceutical state examination Berlin 1835; owner of a pharmacy in Hamburg 1841-1878; Dr. phil. h.c. Königsberg 1846; compiled a large herbarium especially rich in African and Australian collections.
**Abbreviated name**: *Sond.* \[standard form in IPNI: *Sond.*\]
#### Herbarium and types
The Sonder herbarium was sold in parts after his death. The most important parts are at [[Collection MEL|MEL]] and [[Collection S|S]]. – The set at [[Collection S|S]] contains the major part of the South African herbarium, acquired in 1875, including many types of the *Flora capensis*. B. Nordenstamm (in lit. and 1980) informed us that this set contains at least 60.000 specimens; many sheets have detailed annotations in Sonder's handwriting. A list of the holdings of [[Collection MEL|MEL]] (main part of algal herb.) is given by Court (1972). Gandoger also acquired part of the African herbarium but it is not clear whether this set is now at [[Collection LY|LY]]; it contained mainly the classical series of exsiccatae of Drège (8575), Ecklon (4500) and Zeyher (Gandoger 1901). – Other Sonder material is at [[Collection BM|BM]] (some algae), [[Collection C|C]], [[Collection CGE|CGE]], [[Collection DBN|DBN]], [[Collection E|E]], [[Collection E|E]]-GL, [[Collection GRA|GRA]], [[Collection K|K]], [[Collection KIEL|KIEL]] (algae), [[Collection L|L]] (also in herb. Kützing; algae), [[Collection LE|LE]], [[Collection MANCH|MANCH]], [[Collection PH|PH]], [[Collection TCD|TCD]] (algae), [[Collection W|W]] (algae), [[Collection WAG|WAG]]. – *Letters* to D.F.L. von Schlechtendal at [[Collection HAL|HAL]], to F.A.W. Miquel at [[Collection U|U]], other letters at [[Collection G|G]].
