120 J. H. MAIDEN. 
Sieber, Franz Wilhelm (-———— ). Native of Prague, 
Bohemia. He collected in New South Wales for seven 
months during the year 1823, and took considerable and 
excellent collections to Kurope, which he sold in numbered 
sets bearing the labels ‘“‘ Flor. Nov. Holl.” and “‘ Pls. Exot.”’ 
Descriptions of many plants bearing his name as author 
are published in De Candolle’s Prodromus and other works, 
but whether the descriptions were actually the work of 
Sieber, does not transpire. Before he came to Australia 
he published a work “Avis de plantes. . .”’ (Ankiindigung 
von Herbarien). (Prague, 1821) 8vo. which I have not been 
able to consult. He is commemorated in the following
