BALFOUR—NEW SPECIES OF RHODODENDRON, 157 
ash-grey the colour due to an agglutinate pellicle of hair-indu- 
mentum many cells of which become rufous red (the material 
is not sufficient for accurate further description), vestiges of this 
pellicle are seen on older parts of branches. Foliage-buds un- 
known. Leaves petiolate as much as 25 cm. or more long ; 
lamina thickly leathery broadly oblanceolate as much as 20 
cm. long 12 cm. broad, apex rounded with a short tuberculate 
mucro, margin thickly cartilaginous slightly tinted red (recurved 
in dried specimens), tapering to the somewhat wedge-shaped 
base where it is prolonged more or less evidently along the petiole; 
upper surface mat dark olive-green not shagreened and only 
slightly wrinkled glabrous but for the midrib in the narrow 
groove of which are white vestiges of hairs like those on the 
young stems, midrib darker coloured the rest of surface losing 
its groove and becoming convex as it passes into petiole, primary 
veins about 15 on each side very shallowly grooved ; under 
surface grey with a prominent thick red-tinted midrib and pro- 
minent like-tinted primary veins, the grey surface composed of 
a bistrate indumentum, the under stratum a grey pellicle of 
agglutinate rosette-hairs exposed in older leaves as a smooth 
scintillating surface where the upper stratum has fallen off, 
upper detersile stratum forming complete surface in younger 
leaves in patches only on older consisting of funnel-shaped cup- 
hairs broad and open the mouth easily seen usually but where 
crowded together becoming more narrow funnels, each with a 
short stalk and a delicate thin wall of small cells elongated in 
the direction of the axis of the cup, the margin of the cup pro- 
longed into a fringe of short hair-branches which interlace with 
those of adjacent cups; when uncompressed and complete the 
surface appears foveolate; petiole stout flat or convex not 
grooved above about 2.5 cm. long showing traces of the same 
glabra (costa media pilorum juvenilium vestigiis induta excepta), costa media 
percursa menti stratum superum detersile e pilis cupulari-infundibuli-
