BALFOUR—NEW SPECIES OF RHODODENDRON. 179 
discoid stigma. Its capsule ovoid not narrow oblong. Ra. 
vicaritum cannot be identified with Rh. Edgarianum. 
Rh. fastigiatum.—I have not seen the plant from near 
Tatsienlu which Rehder and Wilson identify as Rh. fastigiatum, 
Franch., and am disposed to doubt the identification on the 
ground that Franchet’s species in all the specimens of it which 
I have seen is a Yunnan plant only. One may have a clue to 
Wilson’s plant in Rehder and Wilson’s identification of Franchet’s 
kh. capitatum with it. That isa point I have not yet investigated. 
There is more than one species in the Paris Herbarium under 
the name Rh. capitatum. Even if Rh. fastigiatum be a Tatsienlu 
plant it is not Rh. vicarium. At a glance it can be separated 
by the discontiguous scales of its uniform underleaf indumentum 
so different from the bi-coloured state of Rh. vicarium, and then 
it has 3-5 flowered trusses not 1-2 anda large membranous calyx 
not a nearly obsolete one; 10 long stamens longer than not 
shorter than corolla ; a long exserted style exceeding the stamens 
not included and shorter than the stamens ; an ovoid not narrow 
oblong capsule. Rh. vicartum is very different. 
Rh. flavidum as a yellow-flowered species is readily separated 
from Rh. vicarium. ~ 
Rh. intricatum differs from Rh. vicarium in the same characters 
as does Rh. blepharocalyx, only it has Io stamens. 
Rh. nitidulum.—Is a much broader-leaved species than Rh. 
vicarium and the prominent scintillating scales of the upper- 
leaf indumentum are characteristic and give the leaf a different 
look from the opaque surface with its drying-up scales in Rh. 
vicarium. Its hardly contiguous uniform underleaf scales are 
a contrast to the bi-coloured scales in RA. vicarium. It has a 
membranous calyx with unequal lobes 2 mm. long sparingly 
ciliate at apex whereas the calyx of Rh. vicarium is nearly obso- 
lete and has no cilia but is scale-fringed. Its .funnel-shaped 
corolla elepidote outside with tube about 5 mm. long and oval 
obovate lobes 1 cm. long is a different construction from the 
campanulate corolla lepidote outside with tube about 2.5 mm. 
long and oblong or oblong-oval lobes 8 mm. long in Rh. vicarium. 
Its conic ovary with style longer than stamens contrasts with 
the cylindric ovary and style shorter than stamens in RA. 
vicarium, as does its capitate stigma with the discoid stigma of 
Rh. vicarium. Soulié’s No. 2772 is certainly not Rh. nitidulum. 
Rh. nitidulum var. nubigenum differs chiefly from the type 
in having smaller leaves and larger calyx and by so much is 
more different from Rh. vicarium. 
Rh. polifolium.—As 1 am for the moment in difficulties over 
this species I cannot write from observation. A Paris specimen 
in Edinburgh Herbarium under the name is not the plant and
