30 BALFOUR—NEW SPECIES OF RHODODENDRON. 
pubescent with floccose hairs fewer on upper surface mixed 
with red glands, more on lower, the hairs long with pluricellular 
stipe much branched interwoven particularly on lower surface. 
Leaves petiolate as much as Io cm. long; lamina of parchment- 
consistence oblong-oval as much as 9 cm. long, 3 cm. broad, obtuse 
with a prominent apiculus ending in a red hydathodal tubercle, 
margin cartilaginous slightly recurved, base trunculate or cor- 
dulate occasionally rounded only; upper surface olive-green 
mat shagreened (when dry) glabrous but for traces of juvenile 
hairs and of withered ones in the groove of the midrib, primary 
veins about 12 on each side hardly visible ; under surface paler 
with prominent pink-tinted midrib and slightly raised reddish 
primary veins, the midrib bearing a few short red glands, rest 
of the surface coated with a thin rufescent detersile indumentum, 
the long-branched juvenile hairs now infiltrated with red secre- 
tion and agglutinated in small rufous tufts, the intervals between 
occupied by shorter floccose hairs and many short red ovoid 
glands ; petiole about 1 cm. long stout wrinkled glabrescent with 
traces of floccose hairs and red glands. Flowers about 8 in a 
short racemose umbel, rhachis floccose about 5 mm. long; 
bracts and bracteoles unknown ; pedicels about 1.3 cm. long 
expanding into an oblique anthopode, elongating in fruit, strict 
pale green glandular with long-stalked red ovoid glands mixed 
sometimes with floccose red greasy hairs especially at top and 
bottom. Calyx small cupular 5-lobed fleshy about 1 mm. long 
glandular with red shortly-stalked glands; lobes rounded red- 
gland-fringed. Corolla campanulate rose without blotch or 
spots about 3.5 cm. long puberulous inside, glabrous outside 
5-lobed ; lobes rounded about 1.8 cm. broad and long emargi- 
nate. Stamens 10 unequal shorter than corolla, longer about 
2.5 cm. long with anther 2 mm. long, shorter 1.2 cm. long 
with anther 1.5 mm. long; filaments slightly widened down- 
wards, from the base upwards puberulous, in shorter stamens to 
about middle. Disk glabrous. Gynaeceum longer than stamens 
about same length as corolla; ovary conoid truncate about 
7 mm. long grooved clad with rufous long setulose ascending 
hairs mixed with short-stalked stout orange-coloured or red 
glands ; style stout glabrous expanded at top into a disk forming 
a lip to the lobulate discoid stigma. Capsule oblique to pedicel 
slightly curved about 2 cm. long 5 mm. in diameter black or 
dark brown somewhat scabrid, splitting by 5 valves from apex 
leaving a narrow stylopod, style persistent in fruit, calyx a 
fleshy basal ring; seeds pale chestnut-brown scimitar-shaped 
about 2.25 mm. long .75 mm. across, testa striate not winged, 
chalazal end apiculate funicular with a fringed aril
