Dwarf shrub about 1 m. high with many straight branches 
at first about 3 mm. in diameter and tomentose with branched 
interlocking closely adpressed hairs, annual growths short, each 
growth about 2.5 cm. long producing some 3-4 leaves rosette- 
fashion at the top which persist for 2-3 years and when they fall 
leave a nodular swelling on the stem marking top of the annual 
growth, bare below but girt at the base with the persistent 
outermost scale-leaves of the foliage-bud which remain for several 
years. Outermost persistent scale-leaves of the foliage-bud few 
(5-6), crustaceous oval or elliptic or oblong apiculate or tailed 
tomentose along the midrib outside, the apiculus densely clad with 
rufous hairs, margin floccose-ciliate ; inner scale-leaves ligulate 
mucronulate membranous longest about 2 cm. long 4 mm. broad 
yellowish with long marginal cilia, rufously hairy at the mucro ; 
young foliage-leaves revolute floccose on upper surface the 
hairs falling as the leaf opens. Leaves petiolate as much as 6cm. 
long; lamina thickly leathery obovate or oblong-obovate as 
much as 5.5 cm. long 2.5 cm. broad obtuse with a rounded 
hydathodal red mucro, margin cartilaginous plane, base pro- 
longed as a narrow wing upon the petiole; upper surface 
olive-green mat, glabrescent but with traces of the juvenile
