Nat. Okd. XV. MALVACEAE. 
Australia is remarkable for the few genera and species of Maloace* which it possesses; that Natural 
Order seeming to be replaced by Mttneriacea t to a very striking degree. About eighty species are how- 
ever known, chiefly of the tropical and subtropical genera HibUeut, Sida, and AJbuHlon, though several 
species, especially of the two latter genera, extend to South-eastern Australia. The Order is eminently 
a tropical one.
