mixed with short ones; bracteoles longer than pedicels and 
calyx about 8 mm. long filiform below and glabrous at base 
pilose upwards and expanded at end into an oval limb woolly 
and lepidote ; pedicels short 6 mm. long sometimes longer to 
about 8 mm. red lepidote and puberulous. Calyx minute not

Rh. hemitrichotum is a plant of the facies of Rh. mollicomum, 
Balf. f. et W. W. Sm. and is a more northerly development of 
the same phylum in the Scabrifolium series. It may be at once 
recognised by the white under side of the foliage-leaves—the 
coloration is due to wax-coloured elongated rod-like papillae— 
and the absence of hairs on this surface except for a few on the 
midrib. In Rh. mollicomum the surface is green and downy. 
The features exhibited by the peltate scales deserve notice. 
These scales on the leaf under side have stout stalks and the disk 
is ovoid transversely to the stalk, sometimes almost globular. 
There is no fringe. The scales are sunk in deep pits so that only 
about half of the disk is above the surface.
