The rich golden-brown tint of the under-leaf indumentum 
is a conspicuous distinctive character of Rh. phaeochrysum 
amongst like forms, of which the likest are Rh. Beesianum, Diels 
and Rh. fulvum, Balf. f. et W. W. Sm. These three species 
cannot be mistaken one for the other. Rh. lacteuwm, Franch., 
which is also an ally, has the rosette-haired indumentum of Rh. 
Beesianum not the matted-haired type of Rh. phaeochrysum, 
and then it has broad obovate leaves, yellow and creamy-yellow 
flowers. The only other species which I mention here as an 
ally is Rh. Traillianum, Forrest et W. W. Sm., and it has the 
powder-like indumentum of Rh. Beesianum not the felted 
indumentum of Rh. phaeochrysum; also the indumentum cf 
Rh. Traillianum is at first grey-green and turns to red-brown in 
the older leaves.
