Sieber met Cunningham, who showed him 150 specimens of Acacias. He 
collected about 1,500 species in 120,000 specimens, and spent a considerable time in 
collecting, also, zoological and ethnological specimens. 
Sieber’s Phanerogam® were worked up by Reiclienbacli and himself, his 
Pilices by Kaulfuss, the Musci by Schwagrichen, the Algae hy Mertens. 
The novelties which Sieher brought from Australia are described and figured 
O O 
in Reichenbach’s “ Hortus Botanicus, liortorum vivorum siecorumque novitates 
illustrans. Cent. I.” (Leipzig, bei Knoblauch, 1824-25. The Australian plants 
begin with Decade viii.) 
Sieber’s grasses were published separately as “Agrostotheca,” and seem to have 
been determined chiefly hy Nces von Esenbeck. An enumeration of the species is 
to he found in the latter’s “ Flora” from 1825. 
On pages 296 and 297 of Dietrich’s paper is a list of the 645 Phanerogams 
Sieber collected from “Port Jackson to the Blue Mountains,” which contains an 
enumeration of the fifty-seven new sjtccies described by him. Most, if not all, will 
be found enumerated in the Flora Australiensis, but this list is certainly valuable 
to workers. 
A list of Sieber’s works is given in Pritzel.
