of the branches, the last-formed leaf or two leaves markedly 
smaller than the others, falling off with the flush of the following 
year. Young twigs about 2 mm. in diameter densely setose, 
the long setae covering the lepidote surface beneath, which has 
peltate scales with wide umbo and equal fringe, setae and scales 
disappearing more or less in second year; older branches at 
first dark grey then decorticating and exposing a red-purple 
smooth surface. Foliage-leaf bud nestling in centre of leaf- 
rosette, the last leaf of rosette smaller than others with its 
broader petiole adpressed to the bud; outer scales-leaves 
oblong broadly triangular and rounded, lepidote outside and 
puberulous, setulosely ciliate, mucronulate and slightly keeled, 
persisting on the branches for one or two years, inner spathulate, 
obtuse, membranous, as much as 2 cm. long, 8 mm. broad, lepidote 
and puberulous outside, ciliate, carried up on the elongating 
shoot ; young expanding leaves conduplicate convolute, densely 
lepidote on both surfaces, setulose on upper surface and on 
margin. Leaves petiolate, as much as 4.5 cm. long; lamina 
thickly coriaceous, elliptic or oblong-elliptic, as much as 4 cm. 
long, 2 cm. broad, rounded at the shortly mucronulate tuber- 
culate apex, margin setulose-ciliate, base obtuse or rounded ; 
upper surface mat pale green; midrib grooved, primary veins 
about 8 on each side, hardly visible, whole surface including 
midrib more or less setulose and punctulate with withered 
peltate scales or marked with traces of the juvenile setae and 
scales; under surface somewhat tawny brown with prominent 
midrib and hardly visible primary veins, densely lepidote with 
partly contiguous partly discontiguous peltate scales never more 
distant than the diameter of the scales, the midrib lepidote 
without bristles or with a few at the base, scales somewhat 
unequal in size a few scattered ones much larger than others, 
each with a very broad umbo and very narrow entire fringe 
all infiltrated with orange or reddish secretion, intervals between 
scales green grey beset with rod-like epidermal papillae; petiole 
rosulatim confertis ; alabastrorum perulae persistentes, vernatione conduplicato- 
convoluta. Folia coriacea, elliptica vel oblongo-elliptica, ad 4.5 cm. longa, 2 cm.
