106 BALFOUR—NEW SPECIES OF RHODODENDRON. 
several outer perulae half foliar with a broad red vaginal portion 
and upper green lamina gradually becoming more scale-like and 
acuminate ; intermediate broadly rounded firm red mucronulate 
quite glabrous ; innermost thinner and glutinous with colleters 
on back cemented to form the chamber for the foliage-leaves, 
on expansion submembranous carried up on the elongating 
shoot red foliaceous about 2.5 cm. long 6 mm. broad with an 
ovoid limb tapering upwards into a long acuminate point ending 
in a red hydathode and downwards into a broad petiole a 
little shorter than the limb; young leaves dark purple with 
red venation revolute glabrous. Leaves shortly petiolate, at 
maturity as much as 16.5 cm. long but often less sometimes only 
about one-third that length ; lamina thickly leathery obovate 
typically with the outline of a jargonelle pear, the shorter leaves 
sometimes only oblong as much as 14.5 cm. long 6 cm. broad, 
apex rounded often truncate and retuse in the middle with a 
stout tuberculate red mucro, margin broadly cartilaginous entire, 
often purple-red, base cordulate; upper surface coated with a 
grey thin pellicle of wax (soluble in benzole) covering a bright 
green or purple reddish foveolate surface, midrib and primary 
veins (about 15 on each side very regular and ascending) slightly 
grooved under the wax-pellicle; under surface in the leaves 
with green upper surface tawny green, in leaves with red upper 
surface tawny, elevated midrib and primary veins (not raised) 
red tinted the whole surface most glabrous and smooth but in 
dry state ultimate venation sometimes appearing as a slightly 
raised reticulum ; petiole broad red and glaucous as much as 
2 cm. long usually less, grooved without hairs or glands. Flowers 
in a terminal many-flowered shortly racemose umbel, as many as 
12 flowers in the umbel, rhachis dark purple glabrous as much as 
1.5 cm. long; bracts and bracteoles unknown ; pedicels stout 
about 2 cm. long dark red-purple glaucous glabrous expanding 
into the cup of the calyx. Calyx cupular-campanulate about 
1 cm. long 5-lobed; cup somewhat fleshy glabrous 2-3 mm. 
long ; lobes subcrustaceous ovate or oblong-oval with rounded 
tip striate and glabrous persistent and enlarging around fruit. 
Corolla tubular-campanulate faintly spotted posteriorly and with 
a median basal blotch about 4.5 cm. long somewhat fleshy ; tube 
in narrow lower part one half length of corolla retuse and 
5-pouched at base with darker blotch in each pouch, glabrous 
outside and inside, expanding into a broad spreading 5-lobed 
limb ; lobes broad rounded emarginate about 1 cm. long 2 cm. 
broad. Stamens shorter than corolla and gynaeceum ; filaments 
glabrous. Disk glabrous. Gynaeceum about as long as corolla ; 
ovary stout ovoid grooved truncate densely glandular with 
ovoid red-stalked glands with wax bloom between the glands ;
