An evergreen sniall .slirnb, usually verticellato-ramose ; branches sub- 

 purpureo-rnfous ; branclilets terete, gracile, rufous, adpressed-setoso-strigose. 

 Leaves small, crowded at the top of branclilets, Ijut alternate in shoot, 

 erect-patent, linear-oblanceolate to oblanceolate, mucronato-acute,. gradually 

 attenuated below to a ])etiole, entire, adpressed-pilose and adpressed-ciliated 

 with pale-rufous hairs, whicli are white on the U|)per surface and denser 

 towards the petiole, suV)Coriaceous, often minutely punctate under lens beneath, 

 .5-29 mm. long including the petiole, li-7^mm. wide; veins loose and 

 unequally 2-4 on each side but usually inconspicuous. Flow(*rs 1-C to a 

 terminal bud, shortly pedicellate, about 3 cm. across, ])urpureo-lilac ; pedicel 

 longer than sepals, 4-G 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-G mm. long, 

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

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

 IJ mm. long, persistent. Corolla slightly oblique and cam[)anulato-in- 

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

 orbicular or elliptico-orbicular, rounded at apex ; tube al)Out 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, 

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

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

 5-lol3ed on face. Capsule ovoid, shortly attenuated above, about 9 nmi. 

 long, adpressed-strigoso-pilose, 5-carpellary ; seeds minute, elliptical and 

 subangulate, ferruginose. 



Hah. Prov. Tosa : Takaoka-gori {T. Makino ! 1885), Sodayama-mura 

 {T. 3laldno\ April 5, 1887), Kamibun-mura {T. 3fnhno\ Dec. 1888, 

 January 9, 1892). 



This comes near Rhododendron serpyllifolhcm Miq., but flowers larger 

 and 1-G-fasciculate ; leaves narrower, more tapering, and more hairy ; or 

 a variety of Hh. indicum Sweet? It is rather common on hill sides in 

 the middle parts of the province of Tosa in Shikoku.
