        Council of Heads of Australasian Herbaria |  | 
Visited the Swan River colony, Western Australia, from December 1838 to January 
    1842, making a collection of about 3000-4000 specimens from an area extending 
    from about 100 km north of Perth south to Albany and east to the vicinity 
    of Cape Riche. 
These collections (with a few by other collectors) form the 
    basis for one of the landmark works on Western Australian botany, Plantae 
    Preissianae... (Lehmann, 1844-1848). 
Preiss' collections were made 
    up into various sets and subsequently dispersed, now being found in at least 
    25 different herbaria. The standard reference set for Plantae Preissianae 
    is now at LD, with other substantial numbers of specimens at C, DBN, G, HBG, 
    LE, MEL, MO, P, S and W. For minor holdings in other herbaria. The MEL collections 
    were purchased as part of the Steetz and Sonder 
    herbaria.
