ciliate, upper surface dark green, scabrid, lower pale to gray green, 

 clothed with soft appressed hairs, costa and secondary veins impressed 

 on upper, raised and hispid on lower surface, secondary veins spreading 

 at right angles, branching; petioles 0.8-2 cm. long, bearded with stiff 

 gland-tipped hairs. Flowers 4 to several in clustered lateral fascicles; 

 pedicels stout, 1.5-2 cm. long, densely clothed with rufous brown pilose 

 hairs many of them gland-tipped; calyx membranous, pilose, saucer- 

 shaped, deeply 5-toothed, teeth unequal, triangular or lance-shaped, 

 0.2-0.8 cm. long, acute, ciliate; corolla pink, funnelform-campanulate, 

 5-8 cm. long and wide, deeply 5-lobed, tube narrow, 1.5-2.5 cm. long; 

 lobes spathulate, usually rounded; stamens 10, shorter than corolla, 

 filaments slender, papillose in lower half; pistil overtopping stamens, 

 nearly as long as corolla, ovary ovoid, rather less than 0.5 cm. long, 

 densely clothed with appressed rufous-brown pilose often gland-tipped 

 hairs, style glabrous, stigma capitate. Fruit rostrate, cylindric, 4.5-7 

 cm. long, about 0.5 cm. wide, furrowed, with remains of style forming 



prominent beak, scabrid, with few scattered stipitate glands, pedicel 

 curving. 



Habitat: eastern China, southeastern Chekiang, Fokien and Hongkong. 



This is a very distinct Rhododendron with thin oblong-lanceolate 

 strongly veined leaves with soft pubescence and often gray on the lower 

 surface, ciliate margins, bearded petioles, shoots and pedicels and long 

 cylindric scabrid fruit. It was this first Rhododendron species discovered 

 wild in China being found at Fort Victoria, Hongkong in 1849 by Captain 

 J. G. Champion who sent seeds to Kew and after whose wife it is named. 

 For many years it was considered endemic in Hongkong but in 1905 it 

 was found in Fokien province by S. T. Dunn and quite recently in the 

 southeast corner of Chekiang province. However, it appears to be a 

 rare plant. It is tender and has never become common in gardens.
