82 THE AZALEAS OF THE OLD WORLD 



ovate-lanceolate, with an acute mucronate apex and cuneate base, but occasion- 

 ally they are broad-ovate or elliptic. The petioles are from 0.4 to 1.2 cm. in length, 

 glabrescent, purplish, and often slightly glaucescent on the under-side. The flowers 

 are usually in pairs at the end of the naked branchlets, but are sometimes soli- 

 tary, and occasionally are in 4- or 5-flowered clusters; the corolla is from 4 to 

 5 cm. across, spotted with red-purple on the posterior lobes; it has a short, narrow, 

 funnel-shape tube and deeply cleft, spreading lobes. The pedicels are villose; the 

 minute, 5-lobed calyx and the ovary are clothed with gray or yellow-brown, 

 straight appressed hairs. The 10 stamens are of nearly equal length and as long 

 as the corolla, the filaments are glabrous, curved and the anthers purple. The 

 style is longer than the stamens and is curved upward and has a capitate, slightly 

 lobed stigma. The fruit is cylindric, from 1 to 1.5 cm. long, slightly furrowed, 

 and clothed with gray or yellow-brown, villose pubescence, and is borne on a 

 straight pedicel. 



From those species with which R. Mariesii has been confused it is readily dis- 

 tinguished by its leaves. The flowers are of a different color from those of the 

 Japanese species, the corolla is differently shaped and there are other distinctions 

 of importance. In Tokyo I saw the types of Hayata's two species cited and could 

 find nothing by which to distinguish them from R. Mariesii. 



This Chinese plant was discovered by Fortune, probably in Chekiang province, 

 and afterward by Charles Maries on the Lushan mountains behind Kiukiang in 

 the spring of 1878. It was introduced into Kew gardens through seeds sent from 

 the neighborhood of Ichang in 1886 by Augustine Henry; in 1900 I sent seeds 

 to Messers Veitch from south of Ichang. This Azalea flowered for the first time in 

 the Temperate House at Kew in April, 1907. Bean does not consider it to be 

 hardy. I have not heard of its being cultivated in America.
