BALFOUR—NEW SPECIES OF RHODODENDRON. 127 
grooved, primary veins about 12 on each side also shallowly 
grooved, the whole surface glabrous even in the midrib groove, 
only a trace of the juvenile glands here and there visible ; under 
surface glaucous with a wax bloom often purpling covered with 
close-set low dome-shaped wax-secreting epidermal papillae and 
sprinkled with short cauliflower hairs and red glands, the midrib 
red and raised and faintly warted with remains of glands, the 
primary veins red and also slightly raised; petiole as much as 
1.5 cm. long reddening grooved on upper side glabrescent but 
showing traces of the juvenile sessile glands on under side and 
stalked ones upper side. Inflorescence a terminal 5—6-flowered 
very shortly racemose umbel, rhachis about 7 mm. long sparingly 
glandular and floccose ; flowers in bud orange-red ; bracts falling 
as inflorescence expands, inner ones oblong spathulate rounded at 
top with a short mucro silky outside and inside ; bracteoles linear 
widening upwards and then tapered to the point about 7 mm. long 
-35 mm. broad shorter than pedicels sparingly hairy from base and 
towards top glandular, apex ending in a bristle ; pedicels strict 
somewhat unequal as much as 1.5 cm. long glandular with stalked 
red glands expanding under the calyx. Calyx foliaceous 
yellowish about 7 mm. long ; cup about I mm. long flat sparingly 
glandular outside, lobes elliptic or oblong unequal posterior pair 
largest as much as 6 mm. long 3 mm. broad almost eglandular 
on back regularly gland-ciliate at margin. Corolla yellow 
without blotch or spots barely 3 cm. long campanulate from base 
fleshy glabrous outside and inside, gibbous and retuse at base 
especially on posterior side; lobes short and broad about 
1.3 cm. long 2 cm. broad undulate and slightly emarginate. 
Stamens 10 unequal much shorter than corolla, longest about 
1.9 cm. long with anther 3 mm. long, shortest about I cm. 
long with anther 1.5 mm. long; filaments stout white not ex- 
panded downwards glabrous; anthers bright brown. Disk 
dark green puberulous below ovary. Gynaeceum about 2 cm. 
long shorter than corolla about equalling longest stamens ; ovary 
about 4 mm. long thick conoid truncate grooved glandular with 
red ovoid glands on long stout ascending stalks ; style glandular 
throughout the glands shortly stalked, expanding into a clavate 
tip forming a prominent lip below the broad lobulate discoid 
stigma.

A plant of the Souliei series and of the alliance of Rh. Wardii, 
W. W. Sm. and RA. croceum, Balf. f. et W. W. Sm., distinguished 
from both of them by the white-grey of the purpling under- 
surface of the leaves. It has not the glands on the outside of the
