This is a most distinct species, and if the flower tint is only 
right the plant should be an acceptable one in gardens. It is 
most floriferous, and in the dried specimens the flowers retain 
more colour than is the case in kindred species. In habit it 
recalls the Rh. yanthinum of our gardens, but the thickly-set 
scales of the under-leaf indumentum in that plant and its allies 
readily distinguish it and them. The scattered scale-indu- 
mentum on the under-leaf surface resembles that of Rh. rigidum, 
Franch., but Rh. sycnanthum may be recognised by absence of 
the wax bloom on the leaves, the total absence of hairs from 
young twigs, petiole, and groove of midrib on upper leaf-surface. 
This surface from the first is glabrous, not a hair appearing on 
it even in the groove of the midrib or in the groove of the petiole, 
nor is there a peltate scale. The few cilia which fringe the leaf- 
margin in bud fall off with expansion from the bud. Two other 
characters separate Rh. sycnanthum from Rh. vigidum—the 
flower-pedicels and calyx are lepidote and the flowers them- 
selves larger.
