This species is distributed from Fokien and Chekiang provinces of eastern 

 China westward to southeastern Szech'uan. On the Lushan mountains round 

 Kuling it is common and north and south of Ichang it is very plentiful on cliffs 

 and in thickets between altitudes of 300 and 1300 m. Its pleasing pink to rose- 

 colored flowers open before the leaves unfold and in late April and May it is a 

 conspicuous wayside shrub. Curiously this and R. molle G. Don are the only 

 deciduous leafed species in the whole of China except R. Farrerae Tate from 

 Hongkong and the adjacent territory. Maries' Azalea is an upright branching 

 shrub from 1 to 3 m. tall, rather narrow, with verticillate, twiggy, ascending 

 branches which are shining, yellow or chestnut-brown during the first year and 

 afterward pale gray. When young the shoots and leaves are covered with yellow- 

 ish, appressed silky hairs which usually fall away early or may in part persist on 

 the shoot through the entire season. The buds are conic, gray-purple, with ciliate 

 bud-scales glabrescent without and villose on the inner surface. The leaves at 

 maturity are chartaceous, dark green above, pallid below, prominently reticulate, 

 with the principal veins slightly impressed on the upper side and raised on the 

 lower side; they vary from 3.5 cm. to 7.5 cm. in length and from 2 to 4 cm. in 

 width, and are always the broadest below the middle. The prevailing shape is
