BALFOUR—NEW SPECIES OF RHODODENDRON. ae 
«°” Rhododendron Albertsenianum,* G. Forrest. 
Eglandular shrub about 2 m. high with stiff straight 
branches. Branches a year old about 2.5 mm. in diameter 
coated with a grey-white thin tomentum of floccose interwoven 
hairs becoming glabrescent, decorticating in the second year. 
Foliage-buds narrow oblong; outermost scale-leaves more or 
less rotundate below shortly keeled and tailed, the tail half as 
long as the base, outside thinly tomentose with buff-coloured 
interwoven hairs below, the hairs white in upper part, ciliate ; 
intermediate scale-leaves oblong dull crimson-coloured slightly 
keeled mucronate clad outside like the outermost scale-leaves, 
ciliate ; innermost scale-leaves ligulate-spathulate acuminate 
netennck in upper half, membranous ciliate as much as 4 cm. long 
6mm. broad ; young leaves revolute in bud densely tomentose on 
both surfaces, hairs of the upper surface floccose branched from 
the base and upwards forming long unicellular pointed thick- 
walled curved and undulate branches which interlock, falling off 
shortly after expansion, hairs of the under surface persistent, 
of two kinds, rosette-hairs covered by hairs resembling those 
of upper surface. Leaves petiolate as much as 10.5 cm. long ; 
lamina leathery narrowly oblong or sublanceolate as much 
as 9.5 cm. long 2.5 cm. broad, obtuse with a conspicuous red- 
tipped mucro, margin cartilaginous nearly plane, base oblique 
obtuse ; upper surface olive-green somewhat shagreened (when 
dry) glabrescent but with vestiges of juvenile hairs particularly 
in groove of midrib, primary veins some 12-15 on each side 
slightly grooved ; under surface buff-coloured with a prominent 
midrib, whole surface tomentose with a bistrate indumentum, 
the upper stratum of hairs with a long axis and many narrow 
unicellular pointed curved and undulate interwoven branches 
forming a woolly surface at first and later more or less detersile,
