An evergreen small shrub, usually verticellato-ramose ; branches sub-

 Leaves small, crowded at the top of branchlets, but alternate in shoot, 

 erect-patent, linear-oblanceolate to oblanceolate, mucronatn-acute, gradually 

 attenuated below to a petiole, entire, adpressed-pilose and adpressed-ciliated 

 with pale-rufous hairs, which are white on the upper surface and denser 

 towards the petiole, subcoriaceous, often minutely punctate under lens beneath, 

 5-29 mm. long including the petiole, 1 J-71 mm. wide; veins loose and 

 unequally 2-4 on each side but usually inconspicuous. Flowers 1-6 to a 

 terminal bud, shortly pedicellate, about 3 cm. across, purpureo-lilac ; pedicel 

 longer than sepals, 4-6 mm. long, adpressed-pilose ; bud-scales ovato-oval, 

 often mucronate or with an elongated point, concave, chartaceo-membrana- 

 ceous, pilose in centre dorsally, ciliated above, not viscid, 3-6 mm. long, 

 deciduous. Sepals small, oval-elliptical or ovato-elliptical, obtuse or rounded 

 at apex, pilose externally, ciliated with erect pilose hairs, nearly nerveless, 

 11 mm. long, persistent, Corolla slightly oblique and campanulato-in- 

 fnndibnliform, 5-fid, spotted on the posterior side internally glabrous ; lobes 

 orbicular or elliptico-orbicular, rounded at apex ; tube about as long as lobes. 

 Stamens often 6 and sometimes 5 or 7 intermixed, unequal, the longer ones 

 as long as the corolla ; filament filiform, paleaceo-pubescent below ; anther 

 obovoid-oblong, but obovoid in those of shorter filaments. Ovary ovoid, 

 pilose with erect hairs, about 2 mm. long ; style filiform, glabrous, slightly 

 longer than the longer stamens and corolla ; stigma thick, truncate and 

 5-lobed on face. Capsule ovoid, shortly attenuated above, about 9 mm.
