Fortunately this description was accompanied hy a fairly good drawing (Tab. 
IY, reproduced in Plate 188), which, however, represents the plant in flower and 
not in fruit. I have not been able to see the type specimen; I do not even know 
whether it was preserved. 
Then we have the brief description of the Prodromns , in which De Candolle, 
who quotes and compares Sieber’s specimens wherever he can, surmises that it may 
be Sieber’s No. 452. 
Bentham (B.F1. ii, 366) says that the surmise is correct; in other words, that 
the A. amoena of Sieber (not of Wendland) is A. rubida A. Cunn. The Prodromus 
description follows. 
A. amoena. (Wendl., Diss. n. 8. t.4) phyllodiis oblongis basi valde attenuatis uninerviis margine 
antico glandulis 1-3, capitulis racemosis, floribus 5-fidis. Hab. Nova Hollandia. Ad sequentem valde 
accedit sed racemi phyllodiis dimidio breviores. Petala 5 distincta et ovarium tomentosum.-Planta Sieb. 
pi. exs. nov.-holl. n. 452 (A. rubida, A. Cunn. J.H.M.) a Wendlandiana differe videtur phyllodiis vix 
marginatis antice 1-glandulosis. An eadem 1 (v.s.) (DC. Prod. 2 (1825), p. 452.)
