Rh. sphaeranthum, Balf. f. et W. W. Sm. is a small virgate 
bush with leaves and flower trusses recalling Ledum. Rh. 
ledoides, Balf. f. et W. W. Sm. and Rh. radinum, Balf. f. et W. W. 
Sm. are its nearest allies in the Cephalanthum series, to which it 
belongs. Like them both in its leaves, it differs from Rh. radinum 
the scale-leaves of the foliage buds deciduous, a 
character in which it resembles Rh. ledoides. Differentiating 
characters are the lepidote not puberulous rhachis of the 
inflorescence, its long prophylls much longer than the calyx, 
and its lepidote corolla. 
The species is in cultivation and has flowered in Britain.
