BALFOUR—NEW SPECIES OF RHODODENDRON. 181 
ovate. Upper surface has scales “‘ flavidis lucidis ’’—the surface 
is opaque in Kh. vicarium. Scales on under surface not con- 
tiguous and dark-coloured ones are scattered evidently punctulate 
in kh. verruculosum, in Rh. vicarium equally distributed. Flowers 
solitary, but 2 in Rh. vicarium. Calyx-lobes ovate or rounded 
1-2 mm. long densely villous-ciliate, in Rh, vicavium obsolete 
scale-fringed. Corolla funnel-shaped with tube 4 mm. long but 
in Rh. vicarium tube campanulate 2.5 mm. long—in both corolla 
is lepidote. Stamens 7-8 not 10. Ovary conic not cylindric. 
Style much longer than stamens, not shorter as in Rh. vicarium. 
Stigma capitate not discoid. Quite distinct from Rh. vicarium. 
Rh. Websterianum is one of the silvery underleafed forms with 
large flowers and long exserted style. It is not like Rh. vicarium. 
Rh. violaceum.—Has the same habit. Leaves are sometimes 
acute never in RA. vicarium. Flowers 1-3, in Rh. vicarium 
usually 2. Petiole 2-3 mm., the maximum is 2 mm. in RA. 
vicarium. Calyx-lobes 0.5-2 mm., ovate or rounded on a cupular 
base, ciliate at apex but as in RA. vicarium the margin is lepidote 
and often scarious, in Rh. vicarium I have not seen a scarious 
margin nor cilia and the lobes are nearly obsolete the whole 
calyx barely 0.5 mm. long. Corolla funnel-shaped glabrous 
outside, tube 4-5 mm. long, in Rh. vicarium tube campanulate 2.5 
mm. long and corolla lepidote. Ovary conic not cylindric. 
Style exceeding stamens not shorter. Stigma capitate not 
discoid. Capsule ovoid not oblong 5 mm. long not 
Rh. vicarium is nearest to this species but is distinct. From the 
specimen and description I take the main differences to be :— 
Leaves larger and more glossy in Rh. vicariu 
Calyx-lobes much smaller 0.5 mm. long pany more lepidote and 
fleshy eciliate. 
Corolla-tube shorter 2.5 mm, campanulate. Corolla lepidote not 
ett outside puberulous not villous inside. 
Ovary much smaller pect sig 
Style an than stam 
Capsule narrowly oblong 
The type of Rh. violacewm I have seen is Wilson No. 3460, and 
there are two distinct plants under the number—one with discon- 
tiguous underleaf indumentum is certainly not the Rh. violaceum. 
Rhododendron Vilmorinianum, Balf.f.* (Triflorum.) 
An erect bush in cultivation with rigid straight stiff thin 
branches. Branchlets of the year barely 1 mm. in diameter
