Another member of the nas Which centres in Rh. taliense, 
Franch. It has many characters by which it can be recognised. 
Of these an easily observed one is the indumentum on the under 
surface of the typically elliptic to oblong leaves with cordulate 
ase. It is bistrate and the hairs of the upper stratum are 
always agglutinated forming a white shining smooth surface- 
canopy over the underlying hair-layer. As the leaf oldens the 
indumentum cracks and dries but does not fall or peel off. At 
the same time the indumentum becomes brown always at first 
on each side of the prominent pink midrib. Subsequently it 
may become brown all over. This feature recalls the condition 
of the indumentum as it has been described in Rh. favorufum, 
Balf. f. et Forrest, where the splitting is much more marked. 
Rh. flavorufum is without question an ally of Rh. schizopeplum 
but is easily, distinguished by its young yellow under-leaf indu- 
mentum which becomes dark red on older leaves and not only 
splits but scales off in patches.
