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.
