150 BALFOUR—NEW SPECIES OF RHODODENDRON. 
mat olive-green glabrous slightly rugulose not shagreened midrib 
grooved often purpled, primary veins some Io-II on each side 
slightly grooved; under surface everywhere clad with a pale 
buff-coloured bistrate indumentum the raised midrib and primary 
veins also forming a non-scintillating somewhat woolly layer, 
upper stratum more or less detersile composed of long stalked 
narrow funnel-shaped cups, the stalk many-celled giving off a 
few branches, the cup also giving off branches from the sides 
outside hardly forming a rim and deliquescing into many twisted 
branches, the branching so free as sometimes to obscure the 
cup form, under stratum of rosette-hairs with short stalk and 
spreading thin-walled vesicular agglutinate branches forming a 
white persistent crust under the upper stratum and exposed 
when the latter falls ; petiole stout about 2 cm. long 4 mm. in 
diameter purple and clad with remains of an indumentum like 
that of underleaf surface. Flowers in a terminal racemose 
umbel about 20-flowered, rhachis more or less tomentose about 
3.5 cm. long ; pedicels not exceeding 2 cm. in length 1.5 mm. in 
diameter densely tomentose slightly brown-tinted, at top set 
on very obliquely to flower. Calyx saucer-shaped small about 
1.5 mm. long densely tomentose like the pedicel with short 
marginal teeth acute or obtuse. Corolla obliquely campanulate 
fleshy barely 3.5 cm. long on convex side, creamy white with a 
deep basal crimson blotch darkest on 3 or 4 posterior petals, 
slightly pouched and retuse at base glabrous outside and inside 
8-lobed ; lobes rounded or somewhat truncate and retuse about 
I cm. long 1.4 cm. broad. Stamens 16 unequal much shorter 
than corolla and gynaeceum ; filaments slightly expanded down- 
wards puberulous ; anthers pale about 3 mm. long. Disk small 
glabrous. Gynaeceum about 3 cm. long a little shorter than 
corolla; ovary conoid truncate grooved densely tomentose 
with fasciate erect closely packed hairs slightly brown-tinted ; 
style short glabrous expanded at top into a broad discoid 
lobulate recurving stigma. 
Upper Burma. N’Maikha-Salween divide. Lat. 
26° 20" N. Alt. 11,000 ft. In bamboo and mixed scrub. 
Shrub of 6-9 ft. Flowers almost gone, yellowish-white or 
pale yellow with a crimson blotch at base. G. Forrest. 
No. 18,034. May rgr19. 
A species of the Falconeri series finding its nearest ally in 
Rh. galactinum, Balf. {.,* collected by Wilson in Szechwan (RA. 
lacteum, Rehd. et Wils., in Pl. Wilsonianae, i (1913), 545 in part). 
* This plant is Wilson’s No. 4254, and is in cultivation but has not yet flowered. 
Until we have flowers an adequate description is not possible, and the name has 
been attached to the plant in gardens for convenience of reference and distinction 
from Rh. lacteum, Franch., and Rh. fictolacteum, Balf. f. (See Trans. Bot. Soc. 
Edin., xxvii (1916), 104.)
