96 BALFOUR—NEW SPECIES OF RHODODENDRON. 
long, thin glabrous outside obscurely puberulous at base inside 
on the posterior surface, expanding into a 5-lobed open limb ; 
lobes rounded emarginate about 1.2 cm. long 1.2 cm. broad. 
Stamens 10 unequal shorter than corolla and gynaeceum, longest 
about 2.4 cm. long with anther 2.5 mm. long, shortest about 
1.7 cm. long with anther 2 mm. long; filaments widened and 
flattened downwards, from the base puberulous upwards in the 
shortest stamens through half the length, in the longer over less 
distance. Disk puberulous. Gynaeceum about 2.8 cm. long, 
shorter than corolla longer than stamens ; ovary about 3.5 mm. 
long dome-shaped truncate slightly grooved glabrous but with 
hair-crest of simple hairs at the summit around the style; 
style glabrous stout somewhat clavate at top below the discoid 
lobulate stigma. 
W.N.-W.-Yunnan. Mountains north of Atuntzu. Lat. 
28° 35’ N. Alt. 13,000 ft. In open pine forest. Shrub of 
6-8 ft. Flowers white flushed rose with few markings. G. 
Forrest. No. 13,971. June Ig17. 
A species characterised by its sticky leaves. In the older 
leaves the indumentum disappears from the upper surface, but 
the glands leave a varnished surface. The under-leaf indu- 
mentum is distinguished by the great development of glands, 
which often blacken with age and give the whole surface a 
punctulate look. The glands are immersed in what appear to be 
rosette hairs with many stout thin-walled branches, and these 
lying over one another become agglutinated and make a continu- 
ous smooth surface. But the indumentum is not crustaceous. 
No foliage-buds nor young leaves are on the specimens and I 
cannot therefore determine with certainty the form of the hairs 
of the under-leaf indumentum. Other diagnostic marks are :— 
the slightly floccose pedicels, glabrous calyx and corolla, glabrous 
ovary save for a crest of many white simple hairs at its top. 
The position of the species appears to be amongst the many 
species which Forrest has been gathering that show an in- 
dumentum not so simple as that of the Lacteum series and not 
so complex as that of the Roxieanum series.
