Ii BALFOUR—NEW SPECIES OF RHODODENDRON. 
shoots are always fulvous tomentose not glabrous. Its under- 
leaf indumentum does not appear to be deciduous, and the 
_ structure of the indumental hairs is very different. Here they 
are relatively large dense flocks, each with a somewhat long 
stipe of many cells branching off at the top into many long 
twisted threads which do not in dried specimens seem to inter- 
lace to form a surface wool-like layer but stand out like strands 
of a mop, giving a sort of powdery aspect to the whole surface 
of theindumentum. The hair-branches are of medium diameter, 
neither filiform nor broadly vesicular. In Rh. Beestanum 
the indumentum-hairs are true flocks also, but of rosette-type. 
The basal stipe is very short and only some 5 or 6 short broad 
vesicular hair-branches radiate from it, spreading out more or 
less flatly, their walls often beautifully striate. These branches 
are so interlaced as to give rise to a smooth suéde general sur- 
face, which is most characteristic. Then the flocks are de- 
ciduous. Other distinctive characters from Rh. Beestanum 
are :—the leaves are not rugulose on the upper surface, the 
petioles not glabrous but coated with indumentum, the inflor- 
escence umbellate not racemosely umbellate, the shorter more 
delicate pedicels, the smaller flowers, the narrower glabrous 
ovary and the less expanded stigma.
